April 26th 2023 - New Publication on Molsoft's GINGER method for lightning-fast high quality conformer library generation on GPUs.

A paper by MolSoft's scientists and developers Eugene Raush (Princpal Developer), Ruben Abagyan (MolSoft Founder) and Maxim Totrov (CTO) has today been published in the ACS Journal of Chemical Theory and Computation. The paper unveils a novel cutting-edge algorithm called GINGER, which efficiently generates high quality chemical conformers at lightning-fast speeds. This innovative approach leverages neural networks to rapidly predict low-energy conformers from 2D chemical structures. GINGER's efficiency is further enhanced by GPU optimization, enabling rapid processing of large compound libraries. GINGER can convert 150-200 mol/sec on a single Nvidia RTX 4090 GPU making it suitable for the efficient conversion of ultra-large libraries (>1B molecules) when run on a multi-GPU server. The ultra-large libraries can be screened using MolSoft's rapid field-based 3D similarity search engine RIDE or via fast structure-based docking use RIDGE and GigaScreen. GINGER is a separate add-on module to MolSoft's desktop modeling software ICM-Pro and ICM-Chemist-Pro or can be run by MolSoft as a service. Please contact MolSoft with any questions and to obtain an evaluation license or to purchase GINGER.

April 19th 2023 - MolSoft ICM Drives GPU-Enhanced Structure- and Ligand-Based Screening of LCC's Novel Ultra-Large, Stereo-defined, and Diverse Library

MolSoft and Liverpool Chiro Chem (LCC) have partnered to make the LCC's 1.4 Billion ultra-large chemical library available for virtual screening. The database can be screened rapidly via structure or ligand based approaches using MolSoft's unique RIDGE and RIDE flexible docking algorithms ported to modern GPU processors.

LCC's ultra-large library has been converted to 3D conformers using Molsoft's new highly accurate neural network GINGER conformer generator. The database is based on LCC's proprietary collection of chirally pure, sp3-rich scaffolds with a diverse set of ring sizes, ring topologies, and exit vectors. The reaction-based enumeration facilitates transformation of your chiral virtual hits to high-quality physical samples.

MolSoft offers a cost-effective service for rapidly screening the database, with results analyzed by our team of computational chemistry experts. Virtual hits then can be converted to physical compounds using LCC's efficient parallel synthesis laboratories. The library can be screened by MolSoft either through a structure- or ligand-based approach as a service.

Structure-Based Lead Discovery If atomic resolution structures or AlphaFold models of your target protein or nucleic acid are available, screening the LCC database against the structure can be undertaken using MolSoft's high-performance GPU-based RIDGE-docking or deep learning GigaScreen methods. The top scoring compounds will undergo inspection, and a ranked hitlist will be provided along with 3D poses of the top hits in complex with the receptor along with other essential properties.

Ligand-Based Isostere Scaffold Hopping Discovery If one or more lead chemicals are available, the library can undergo screening using MolSoft's Rapid Isostere Discovery Engine (RIDE) approach. This will enable new chemistry with similar 3D pharmacophore properties and shape to be identified from the LCC database. Atom weighting can be employed to highlight the significance of specific moieties, while excluded volumes penalties can be applied to regions surrounding the query molecule, prioritizing hits without bulky extensions in constrained areas.

MolSoft's screening methods are finely tuned for high-performance GPUs, allowing us to swiftly deliver screening results to your company within 1-2 weeks in most cases.

Please contact MolSoft if you have any questions or wish to schedule a call to discuss your project and MoSoft's virtual screening approach of the LCC database. Please contact LCC if you have any questions regarding the ultra-large chemical library.

March 28th 2022 - Efficiently Screen Billions of Chemicals in MolSoft's ICM Software - A new collaboration between MolSoft, Enamine and the NIH

At MolSoft we have been privileged to collaborate with many exceptionally talented Ukrainian scientists and we aim to preserve those ties during this tragic time in Ukraine. Ukrainian companies such as Enamine and ChemSpace are currently relocating to other countries so as to keep serving their customers. We believe that one way the MolSoft ICM community can support them during this time is by maintaining the use of their products and services as normal, and providing them with our services.

You can now use MolSoft's Rapid Isostere Discovery Engine ( RIDE) method to efficiently screen over 48 billion chemical conformers from the Enamine REAL database. This will allow you to find new leads and scaffold hop to new interesting chemistry to aid your drug discovery program and quickly find new drugs for many kinds of diseases. MolSoft has collaborated with the NIH and Enamine to prepare Enamine's REAL database for virtual screening . The REAL database is a reaction enumerated library containing approximately 2 billion chemicals (read more here).

Ruben Abagyan Ph.D. (MolSoft Founder) said "We are excited to collaborate with Enamine and the NIH on another Giga sized screening project. RIDE is already being used routinely by our customers to screen the Giga-sized NIH SAVI library and we have worked with Enamine in the past to develop an efficient search method for REAL. We are happy that our customers will have another option for their drug discovery needs."
Nadya Tarasova Ph.D. (NIH/NCI) said "It was a big scientific and computation challenge to prepare the REAL library conformer database and it took more than 7 million CPU hours to complete but now the library is ready we are excited to see how it will be used by the scientific community to deliver new drugs to the market. We have already started screening the REAL database using MolSoft's RIDE method for drug discovery projects here at the NIH."
Vladimir Ivanov Ph.D. (Chief Sales and Marketing Officer at Enamine) said "We are happy that MolSoft's ICM user community will have access to efficiently screen the REAL database using the RIDE method. At Enamine we have enabled a high synthesis success rate for the REAL molecules and can make them available within 3-4 weeks. We look forward to working with MolSoft and the ICM users to help provide chemicals for their drug discovery projects."
MolSoft's RIDE is a fast 3D molecular similarity search method based on Atomic Property Fields (APF) invented by Molsoft Lead Scientist, Max Totrov, and implemented by Molsoft Lead Software Engineer Eugene Raush and his team. RIDE searches databases of compound conformers for molecules that are isosteric to the query, i.e. have similar 3D configurations and distributions of atomic properties. RIDE is a multi-conformational optimal 3D superposition in which both the query molecule and the molecule in the database are represented in multiple low energy conformations to reflect the flexible nature of both molecules. RIDE is available in the ICM-Pro + VLS package.

Applications screening the REAL database with RIDE include:

MolSoft's ICM provides the Engine for 11 Billion Chemical Screen - Identifying new Hits for Kinase and GPCR Drug Targets

MolSoft's ICM accurate flexible docking, cheminformatics and virtual screening technology provided the unique and powerful engine for a successful screen of as many as 11 billion chemical compounds, potential drug candidates. The USC laboratory of Prof. Vsevolod Katritch report in Nature an approach called V-SYNTHES. The tool performs a ICM-docking based hierarchical structure-based screening of a Enamine REAL Space giga library. The screen resulted in the discovery of new lead compounds for the GPCR CB2 and the Kinase ROCK1.

For many years, MolSoft has been developing methods for fast accurate docking and scoring tools, and incorporating those tools to search giga-sized libraries. These tools include, ICM-Pro docking, GIGA search, and a shape property-based pharmacophoric search method called RIDE. GIGA search and RIDE were applied to the NIH SAVI database and Enamine REAL database.

For V-SYNTHES, ICM-Pro was used as the docking engine as well as for the preparation of the reaction libraries and enumeration of the giga-sized virtual databases. Docking and screening simulations were then undertaken using MolSoft's ICM-Pro Virtual Ligand Screening tools. The docking uses MolSoft's Biased Probability Monte Carlo method, optimized force field, docking score to dock and score fragments of a combinatorial library, and then an empirical score is derived and applied to a much larger library. At the end, the top scoring hits from the library are re-docked and scored again. This hierarchical protocol accelerates the docking and scoring run and makes it applicable to very large databases. The flexibility of the binding pocket was represented using MolSoft's 4D docking methodology which uses an ensemble of structures efficiently for fast and accurate flexible-receptor ligand docking.

Prof. Katritch at USC says "We are very excited to use the MolSoft ICM-Pro technology to address the challenges of screening very large chemical databases for the discovery of drug candidates."

You can view and download additional ICM scripts used for this work at the Katritch lab GitHub site which are ready for use with the ICM-Pro + VLS desktop modeling software.

Please contact MolSoft (www.molsoft.com info@molsoft.com) if you have any questions about how to apply this approach to your drug discovery program.

Sept 1st 2020: Arrakis Therapeutics incorporate MolSoft's ICM PocketFinder and Docking Methods into their Small Molecule-RNA Disovery Platform

Arrakis Therapeutics report a new photoaffinity platform for the analysis of chemical interactions with RNA. The paper in ACS Chemical Biology shows how the method they developed called Photoaffinity Evaluation of RNA Ligation-Sequencing (PEARL-seq) can be used for RNA drug discovery by rapidly identifying ligand binding across many types of RNA. MolSoft's ICM PocketFinder method was used to generate an understanding of where small molecules might bind to Aptamer 21 and then ICM docking was used to predict the docked pose of a probe. The docked pose of the ligand was then used to generate hypotheses around which the binding affinity of the ligand could be improved. The SAR data shows that this method has utility for the design and optimization of new RNA-based small molecule therapeutics.

January 1st 2020: Macrocycle Modeling - MolSoft ICM-Dock Again Performs Well in Industry-Wide Grand Challenge Competition.

The results of the "blinded" D3R Grand Challenge 4 ligand docking competition have been published and MolSoft once again has outperformed a range of other methods for ligand binding pose and activity prediction.

The work led by Max Totrov Ph.D. (Principal Scientist, MolSoft) has been preented at the D3R evaluation meeting and published in the Journal of Computer Aided Molecular Design (see publication here ). The results from the D3R GC4 are presented along with an analysis of ICM performance in a large (246 complex) macrocycle docking benchmark. Sampling of flexible rings is directly incorporated into the ICM docking and the paper describes the best practices for macrocycle docking.

ICM accurately predicted the pose of BACE macrocycle inhibitors to within sub-angstrom accuracy using multiple receptor and ligand-biased docking. ICM was ranked top in the cognate receptor part of the competition where the organizers provided the protein structure bound to protein. Notably, unlike other top ranking methods, for our submission in this subcategory we have not used any ligand template information.

MolSoft's 4D multiple receptor conformation docking method for incorporating induced fit in the binding pocket was used to dock the macrocycles. The method was improved from GC2 (Lam et al 2018) and GC3 (Lam et al 2018 ) by introducing scoring/energy offsets that optimize the choice of receptor conformation used. In the cross-docking stage of the challenge and when applicable the docking was guided by 3D pharmacophore using MolSoft's Atomic Property Field (APF) method (Totrov 2008).

MolSoft would like to thank the organizers for coordinating the D3R challenge and providing a valuable way of independently assessing the performance of the ICM-Docking and 3D QSAR tools.

September 11th 2018: MolSoft publishes Protein-RNA docking method

Click here to read paper by Arnautova et al in J Chem Theory Comput. 2018. Paper Abstract: Protein-RNA interactions play an important role in many biological processes. Computational methods such as docking have been developed to complement existing biophysical and structural biology techniques. Computational prediction of protein-RNA complex structures includes two steps: generating candidate structures from the individual protein and RNA parts and scoring the generated poses to pick out the correct one. In this work, we considered three recently developed data sets of protein-RNA complexes to evaluate and improve the performance of the FFT-based rigid-body docking algorithm implemented in the ICM package. An electrostatic term describing interactions between negatively charged phosphate groups and positively charged protein residues was added to the energy function used during the docking step to take into account the greater role that electrostatic interactions play in protein-RNA complexes. Next, the docking results were used to optimize a scoring function including van der Waals, electrostatic, and solvation terms. This optimization yielded a much smaller weight for the solvation term indicating that solvation energy may be less important for the scoring of protein-RNA structures. Rescoring of the generated poses with the new scoring function led to much higher success rates, while pose clustering by contact fingerprints produced further improvements, achieving a success rate of 0.66 for the top 100 structures.


September 7th 2018: MolSoft Outperforms a Range of other Methods for Docking Pose and Affinity Prediction Accuracy in D3R Grand Challenge 3

The results and methodology used by MolSoft in GC3 are published in a recent article by Lam et al entitled "Hybrid receptor structure/ligand-based docking and activity prediction in ICM: development and evaluation in D3R Grand Challenge 3". Also, you can watch a video recording of Max Totrov's presentation on the results at the D3R workshop here.

MolSoft's submissions ranked first place for docking pose and affinity prediction for all targets according to key criteria and builds upon MolSoft's successful performance in Grand Challenge 2 (GC2) - see Lam et al J Comput Aided Mol Des. 2018 32:187 "Ligand-biased ensemble receptor docking (LigBEnD): a hybrid ligand/receptor structure-based approach"). In GC2 Molsoft ranked first place for docking accuracy and binding energy prediction.

Using MolSoft's ICM-Pro software the team participated in pose and ligand affinity prediction challenges for six different targets including Cathepsin S and five different kinases. The predictions were made using a combination of ICM-docking biased by the Atomic Property Fields (APF) of known ligands acting as templates to guide the pose prediction. The image on the right shows the APF fields for ligand bias for Cathepsin S. This approach provides a way of combining a physics-based docking score as well as a phenomenological APF pseudo energy score for pose ranking. For pose prediction ICM returned a median RMSD for the top pose of 1.7Å and a median RMSD of 1.06Å for best pose of five (Figure 1). The disparity between the average RMSD for top pose and the average RMSD for the best pose of 5 is most likely due to crystal contact effects which were not taken into account in the analysis of the results.

Figure 1: MolSoft's performance in the Pose Prediction challenge of GC3 is highlighted by a red arrow.

For the affinity prediction targets it was important to incorporate flexibility of the binding pocket. This was achieved by using pre-aligned PDB structures for each target from the Pocketome database and then selecting up to 10 representative X-ray structures along with compatible ligands used as APF templates.

In the affinity prediction challenge the docked poses of the ligands were scored using a hybrid approach, machine learning (PLS and RFR) on a combination of Receptor/Physics based terms and Ligand/APF-based 3D chemical similarity terms (APF/P 3D QSAR). Evaluated by Kendall tau ranking correlation across all ligands, ICM ranked first place in affinity prediction for all targets (Figure 2).

June 28th 2018: MolSoft's ICM Ranks First in Independent Covalent Docking Tools Comparison

A recent publication by Scarpino et al compared the performance of six covalent docking methods. They selected a large and divergent set of covalent complexes and assessed how well each software could achieve the crystal structure pose of the covalent ligand.

At a two Angstrom RMSD cut off MolSoft's ICM-Pro software was able to achieve the experimental ligand pose in the Top 1 conformations in 62% of the cases and in the Top 10 conformtions in 88% of the cases. MolSoft's ICM-Pro software outperformed the other programs in all tests including reproducing the experimental binding modes and scoring. ICM also performed well with more challenging flexible ligands with 35 heavy atoms or more. In an interesting side test described in the paper, it was found that ICM-Pro's non-covalent conventional docking procedure also gives a remarkable rate of accurate predictions for covalent ligands to modified receptors (CYS/ALA mutations- 86% near native).

The figure below (from Scarpino et al) shows the re-docking success rate at top 1 pose (dark colors) and top 10 poses (lighter colors).

September 7th 2017: FDA approves Vabomere: structure-based design using Molsoft's ICM was key to its discovery.

On August 29th 2017 the U.S. Food and Drug Administration (FDA) granted approval of Vabomere to RemPex Pharmaceuticals (part of the Medicines Company ). Vabomere is a new antibacterial drug for the treatment of complicated urinary tract infections which is a life threatening condition (click here for FDA Press Release).

Vabomere is a combination of meropenem (previously developed carbapenem antibiotic) and vaborbactam (RPX-7009), a novel cyclic boronate beta-lactamase inhibitor. Structure-based design by MolSoft's scientists (lead by Maxim Totrov Ph.D.) using the ICM-Pro desktop modeling software was key to the discovery of RPX-7009. The novel cyclic boronate chemotype was first modeled in-silico at Molsoft and prioritized for synthesis based on modeling and docking into several beta-lactamase target enzymes.

The work leading up to this discovery was published by RemPex and MolSoft in the Journal of Medicinal Chemistry - you can read more here.


MolSoft ICM D3R Docking Challenge Success

MolSoft's ICM software ranked in first place for average RMSD docking accuracy in the 2016-17 Drug Design challenge competition http://drugdesigndata.org/ (D3R).

Along with over 50 other participants, the Molsoft group led by Maxim Totrov Ph.D.(Principal Scientist, MolSoft), submitted blind docking pose predictions for the Farnesoid X receptor (FXR) which is a drug target for dyslipidemia and diabetes. The MolSoft team used the pocketome (www.pocketome.org) entry for FXR and the ICM-VLS, Atomic Property Fields (APF) and machine learning methods in the ICM-Pro software to predict the interaction of 36 FXR ligands and the binding affinity of 102 other ligands.

In January 2017 the organizers (D3R) distributed the evaluation results which showed that MolSoft's submission ranked first in RMSD for the top scoring pose and was the only one with average RMSD below 2.0A (Figure 1 below). In the Binding Energy Prediction competition ICM APF dock and icm-MMGBSA method ranked in first place and produced the lowest RMSE for Stage 2 Set 1 set of Kd values for 15 ligands (Lam et al 2018).

Mar 13th 2016: Ruben Abagyan (MolSoft Founder) will present at the ACS Meeting in San Diego this Weekend.

Prof. Ruben Abagyan (MolSoft Founder and UCSD) will present at talk at the ACS meeting entitled "Toward predictive structural polypharmacology via flexible docking of ligands to the organismal pocketomes".

Abstract :Identification of molecular targets and pathways affected by drugs, environemtal compounds or metabolites is one of great challenges of computational structural biology. A number of methods addressing the problem at the level of chemistry-based machine learning have been developed. We attempted to develop an approach that would be based on a complete collection of crystallographically determined pockets, the Pocketome, complemented with the co-crystallized ligands. The newest release of the Pocketome contains around two thousands ensembles that can be converted to predictive models, and futher characterized by the noise distribution needed to derive the probability values, as well as, in some cases, additional training sets with pKd, IC50 or other activity data. Each new molecule is docked into those pockets or cumulative pharmacophoric fields and scored according to the model. We demonstrate how this system identifies previously unknown targets associated with adverse effects of some drugs and environmental compounds, as well as repurposing drugs to a different indication. A larger evaluation of this platform is underway a group of computational researchers from Novartis.

June 28th 2015: Ligand Guided RNA Modeling

RNA Modeling A new paper in Nature Chemical Biology describes the discovery of a potent small molecule which has the potential to be used to treat Spinal Muscular Atrophy (SMA) a debilitating motor neuron disease. The disease is caused by a deficiency of Survival of Motor Neuron (SMN) gene which is the most common cause of mortality in children. The pyridazine class of compounds described in this paper enhance SMN2 splicing which elevates full-length SMN protein. It is proposed that the small molecule modulators enhance binding of U1 snRNP to the SMN2 exon 7 5'ss.

Using MolSoft's ICM Alibero method , scientists at Novartis Institute of Biomedical Research were able to model the binding mode of the molecule with RNA (See Figure- left). To model the flexibility of RNA a population of 150 RNA models was generated and the Alibero method was able to determine the model that best separated known binders from non-binders. On the basis of this model they were able to hypothesize that the small molecules enhance the stabilization of the RNA duplex in the 1A bulge major groove.


June 11th 2015: MolSoft and Novartis Collaborate to Develop FOCUS - A global communication and modeling platform for medicinal chemists.

Novartis FOCUS MolSoft and Novartis have developed a new desktop modeling and communication environment for drug discovery called FOCUS based on MolSoft's Internal Coordinate Mechanics (ICM) software. The FOCUS platform is described in a publication in the ACS Journal of Chemical Information and Modeling (see Stiefl et al 2015). FOCUS is a platform that helps users communicate chemical and structural data, develop new ideas and support decision making during the drug design cycle. FOCUS can be integrated into an informatics and high performance computing environment giving the user a single interface to many capabilities.
Novartis FOCUS
FOCUS was recently shown being used by Novartis scientists in a PBS documentary called "Cancer: Emperor of all Maladies". The image shows interaction of Novartis' cancer drug LDK378 with ALK.

FOCUS is the result of more than eight years of collaboration between MolSoft and Novartis. Globally at Novartis there are around 1500 registered users and it has become a popular tool for medicinal and computational chemists as well as structural biologists and bioinformaticians. The core functions of FOCUS can be found in MolSoft's ICM-Chemist-Pro desktop modeling and cheminformatics software product (http://www.molsoft.com/icm-chemist-pro.html). FOCUS contains a wide range of applications including a comprehensive set of feature-rich cheminformatics tools and a 3D ligand editing and design hub. Using MolSoft's ICM scripting language Novartis created customized interfaces that enabled them to build fully interactive html pages, menus, dialogs, panels and table actions all linked to internal and external service calls. The FOCUS development team paid particular attention to make it user-friendly for non-computational researchers.

The Novartis FOCUS development team worked closely with MolSoft's software engineers to build a chemically intuitive and user friendly ligand design interface called the ICM Ligand Editor. The Editor is integrated into FOCUS as well as MolSoft's ICM-Pro and ICM-Chemist-Pro desktop modeling and cheminformatics products. Using the editor, a ligand bound to a protein can be modified in 2D or 3D and the effects of the modification on binding can be immediately calculated and observed. Modifications are stored in the memory, which enables full undo and redo capabilities and the medicinal chemist can conveniently store new designs in fully interactive 3D spreadsheets. Rich graphics tools are available for the representation of the binding pocket surface and interactions between the receptor and ligand. The editor is powered by MolSoft's highly acclaimed ICM docking software and contains options for constrained, induced fit, fragment, and covalent docking. The ligand editor can also be used for 3D pharmacophore modeling using MolSoft's Atomic Property Fields.

Novartis FOCUS

December 10th 2014: MolSoft will host the ChEMBL workshop on Jan 28th 2015

MolSoft is excited to announce that we will host the San Diego leg of the ChEMBL USA tour on January 28th 2015. Please RSVP here.

About the Workshop: Every year, research produces a vast amount of data describing the biological effects of chemical substances. This valuable information, while public, is usually in a form not accessible for systematic data extraction (data mining) and lacks consistent standardization.

ChEMBL is an Open Data database that contains this information manually extracted from the primary scientific literature. The database contains binding, functional and ADMET information for a large number of drug-like bioactive compounds. Data is further curated and standardized (assay read outs and chemical structures) to maximize their quality and utility across a wide range of chemical biology and drug-discovery research problems.

We have recently complemented ChEMBL with SureChEMBL, a web-based daily updated database of full patent text and automatically extracted compound structures. This allows advanced chemistry based querying of the patent literature. We will present an overview of both resources, and then show specific use common usage and data analysis scenarios

June 4th 2014: Introducing MERSi: Mutation Effects with Relaxation of Side-chains in Internal Coordinates

MERSi is a new algorithm available in ICM-Pro that allows you to predict the effect of a mutation upon protein stability and protein-protein binding free energy.

Predict Change in Binding Free Energy upon Mutation The binding free energy change ΔΔGbind, is computed as a difference between the binding free energy of mutant and wild type complexes. To account for structure relaxation upon mutation, side chain re-packing in the vicinity of the mutated residue by a Monte Carlo simulations carried out. "Scan Protein Interface" option allows to mutate all residues (one by one) of the Interacting Part in close contact with the second part of the complex. Documentation | Tutorial

Predicting Change in Protein Stability upon Mutation The stability change is calculated as a weighted sum of a complete set of physically meaningful free-energy contributions, including van der Waals attractions, repulsions, electrostatics, hydrogen bonding, and solvation term. Residue-specific constants that account for the free energies of the unfolded and misfolded states were derived empirically using a large set of experimental data. Mutation of a given residue is followed by Monte Carlo simulations with flexible side chains for the mutated residue and its neighboring residues. Backbone flexibility is also considered for special cases such as proline and disulfide-forming/breaking cystein mutations. Documentation

August 29th 2013: MolSoft wins Competitive Bid to Work with AMG and TB Alliance on the Discovery of new TB Drugs.

MolSoft is excited to announce that they have won a competitive bid to work with AMG and TB Alliance on the development of vital new medicines that can be used to treat Tuberculosis (TB).

TB is a common disease which typically affects the lungs and if not treated correctly can be fatal. The current TB treatment is very long and can result in the patient not adhering to the strict regimen. With the recent approval of Bedaquiline as a treatment for multi-drug-resistant TB it gives hope that new and safe TB drugs can be identified.

In this collaboration, MolSoft will develop ligand-based models using published TB drug activity data as well as internal TB Alliance high throughput screening results. All work will be performed using MolSoft.s Internal Coordinate Mechanics (ICM) molecular modeling and cheminformatics software package which is used worldwide by academic and commercial laboratories. MolSoft will develop ICM 2D fingerprint and 3D Atomic Property Field (APF) models for each of the activity series. The 2D approach uses MolSoft.s proprietary method for generating hashed chemical fingerprints used in chemical search and similarity calculations. The 3D APF method, developed by Molsoft.s Principal Scientist Dr. Maxim Totrov, is a 3D pharmacophoric potential implemented on a continuously distributed grid which can be used for ligand docking and scoring.

Dr. Ruben Abagyan (MolSoft.s Founder and Professor at Skaggs School of Pharmacy and Pharmaceutical Sciences UCSD) says "The collaboration between chemists at TB Alliance and the scientific team at MolSoft represents an exciting application of their ICM ligand-based modeling and screening methods. MolSoft.s scaffold hopping technology is being used successfully in the pharmaceutical industry and it is a sign of this achievement that MolSoft was chosen to work on this project. I am confident that this alliance will give the best chance of identifying a new class of TB drugs."

Once the models have been prepared ICM-VLS will screen >12 million drug-like compounds to each model. High quality novel hits will then be chosen which are suitable according to the project.s pharmacokinetic and cytotoxicity criteria for hit to lead progression.

March 7th 2012: ICM Version 3.7-2c Released

MolSoft is excited to announce the release of ICM version 3.7-2c. The new version can be downloaded from our support site here. The key new features are described below but for a detailed list please see the release notes.

Atomic Property Fields APF is a 3D pharmacophoric potential implemented on a grid (Totrov 2008 and 2011 ). APF can be generated from one or multiple ligands and seven properties are assigned from empiric physico-chemical components (hydrogen bond donors, acceptors, Sp2 hybridization, lipophilicity, size, electropositive/negative and charge). An independent study found that APF is most accurate method for chemical superposition and ligand-based 3D virtual screening compared to several other commercial and academic softwares. (Giganti et al 2010).

3D ligand Editor The ligand editor is a powerful tool for the interactive design of new lead compounds in 3D. It allows you to make modifications to the ligand and see the affect of the modification on the ligand binding energy and interaction with the receptor.

Protein Modeling Inside ICM there are many features for homology modeling and loop modeling. This new option can be used if you have a gap in your protein and you want to find loops in the PDB which fit the gap.

Chemisty A couple of new options in the Chemistry menu.

"Pipe-able" Scripting in ICM New options to pipe icm commands and scripts.

September 6th 2011: MolSoft's ICM Modeling Software Correctly Predicts Agonist GPCR Structure

A couple of years ago scientists using MolSoft's ICM software predicted and published the agonist bound structures of beta-adrenergic and adenosine A(2A) GPCR receptors. The accuracy of these models were confirmed by recently published x-ray crystal structures of these GPCRs. This work is summarized in a recent paper in Trends in Pharmacological Sciences. This work highlights the power of MolSoft's ICM modeling softare for the development of new ligands for GPCRs and also the use of these models for other pharmacological and biochemical studies.


September 1st 2011: Explore the Pocketome using ActiveICM

Prof. Abagyan's lab at UCSD have developed a website called the Pocketome which is an encyclopedia of conformational ensembles of all druggable binding sites that can be identified experimentally from co-crystal structures in the Protein Data Bank. The pocketome ensembles are generated from UniProt and PDB and clusters and validates the binding pockets based on the consistency of the composition between multiple structures. The pockets can then be viewed using ActiveICM or downloaded and viewed using ICM-Browser.


August 10th 2011: GPCR Dock 2010 evaluation undertaken using MolSoft's ICM and ActiveICM tools.

SummaryThe community-wide GPCR Dock assessment is conducted to evaluate the status of molecular modeling and ligand docking for human G protein-coupled receptors. The present round of the assessment was based on the recent structures of dopamine D3 and CXCR4 chemokine receptors bound to small molecule antagonists and CXCR4 with a synthetic cyclopeptide. Thirty-five groups submitted their receptor-ligand complex structure predictions prior to the release of the crystallographic coordinates. With closely related homology modeling templates, as for dopamine D3 receptor, and with incorporation of biochemical and QSAR data, modern computational techniques predicted complex details with accuracy approaching experimental. In contrast, CXCR4 complexes that had less-characterized interactions and only distant homology to the known GPCR structures still remained very challenging. The assessment results provide guidance for modeling and crystallographic communities in method development and target selection for further expansion of the structural coverage of the GPCR universe.


July 7th 2011: New Method to Visualize Protein Mutations Using ActiveICM

This month the Journal of Inherited Metablic Disease published a fully interactive 3D research paper using MolSoft's ActiveICM.

July 26th 2010: ICM-Pro Peptide Design Success Story: Design of a V3 HIV-1 gp120 mimotope.

In the current issue of Nature Structural and Molecular Biology scientists at New York University and MolSoft have reported the identification of conserved structural elements in the V3 crown of HIV-1 gp120 which could serve as epitopes to be targeted by a vaccine against HIV-1. A cyclic V3 mimotope peptide was designed using MolSoft's ICM-Pro by inserting a disulfide bond and four residue linkers between the preserved N and C terminals of V3. The peptide was designed by searching the Protein Databank for polypeptide segments that would match the ends of the V3 strands and the stability and positioning of the disulfide bridge were selected by energy minimization. The resulting mimotope was shown to interact with mAbs 1006, 2219 and 2557. The predicted structure and interactions of the mimotope were confirmed by X-Ray crystallography. This mimotope can potentially be used to design immunogens that could induce antibodies to V3 and other variable regions of gp120.

Holiday Reading! Some Selected 2009 ICM Success Stories


10.20.2009: MolSoft's New Technology Brings Online Publications to Life in Fully Interactive 3D.

Scientific publishing is now going 3D. For the first time in online publishing history, the PLoS ONE journal is publishing original research papers containing fully annotated and interactive 3D objects. This 3D environment provides a "movie-like" experience but with a significant difference - the reader is in control of the scenes and each view is linked directly to the text. This is possible because of a new technology called ActiveICM developed by MolSoft LLC. ActiveICM is now being used for scientific publishing due to a collaboration with scientists at the SGC. Initially the technology is being applied to the life sciences for the 3D display of the atomic structures of molecules implicated in disease. ActiveICM can also be used for any online publication where a 3D view would enhance the subject matter. Click here to see the PLoS ONE collection of papers. Click here to read the press release.

The Molcart Compound Screening Database has been updated. The database is a collection of compounds from 33 chemical vendors who let us know whenever a new set of compounds is added or removed from their database.The database currently contains 8,275,223 compounds and the total number of redundant compounds is 4,474,597. The latest changes to the database are documented here. One of the advantages of the MolCart Compound Screening Database is that we take great care to ensure the compounds that are listed are actually available for purchase. Other compound database collections list compounds that are virtual and in theory can be synthesized but they are expensive and are rarely available for quick purchase. If you are a MolCart customer please update your database collection by clicking here and download individual vendor databases or our non-redundant compilation. If you are interested in purchasing MolCart you can get a 2 week trial license by contacting us at info@molsoft.com.


6.25.2009 Press Release San Diego, CA: Interactive Drug Design with the ICM 3D Ligand Editor

Click to enlarge image.

MolSoft LLC (www.molsoft.com) is a leading developer of breakthrough technologies in computational biology and chemistry. MolSoft has officially released a new ground-breaking tool for the interactive, three-dimensional (3D) design and docking of new drug candidates. The ICM Interactive 3D Ligand Editor is an easy-to-use desktop application that allows a chemist to visualize a receptor-ligand complex and then apply their experience and intuition to explore, design and optimize new drug-like compounds. Recently, this tool was validated in a community-wide evaluation of modeling and docking software where ICM performed very successfully in predicting the pose of a ligand to a G-Protein Coupled Receptor (see Michino et al Nature Reviews Drug Discovery 8: 455-456).

A common scenario in drug design is that a lead compound binds reasonably well to a target protein and the ligand-receptor interactions are known, but the problem of how to improve the binding properties, synthetic feasibility, and metabolic-physicochemical properties of the ligand remains. This is where the power of the ICM 3D Ligand Editor comes in: it allows the chemist to see the ligand-receptor interactions clearly on the computer screen. Chemists can simply explore their new ideas with a click of a mouse in a fully interactive and intuitive 3D environment. The effect of a change to the ligand in terms of its interaction with the receptor is immediately displayed on the screen for the chemist's immediate evaluation.

The pharmaceutical industry is already a major user of MolSoft's ICM 3D Ligand Editor technology and industry feedback has enabled MolSoft's developers to build a tool suited for chemists working in drug discovery research. Dr. Eric Martin, Director of Computational Chemistry at the Novartis Institute for Biomedical Research says "The ICM ligand editor is an extremely effective drug design tool for interactively merging the rigor of complex molecular calculations with the intuition of experienced medicinal chemists. We use it extensively both 1-on-1 at the graphics workstation, and in team meetings using a 3D projection system".

So how do you use the ICM 3D Ligand Editor? The process is simple and designed to make life easier for the chemist. First, the ICM 3D Ligand Editor displays the crystal structure or model of the receptor-ligand complex along with the properties of the pocket, ligand solvent accessible surface, ligand strain or unsatisfied hydrogen bonds. The chemist can then start exploring ideas for improving the ligand by selecting a new chemical group and adding it to the ligand. The binding energy and interaction with the receptor is immediately assessed and displayed on the screen. The chemist has access to a full panel of chemical groups, linkers, bond types, stereo/isomer options and atom selections, which can be used to quickly try many different ideas. Importantly, should something be undesirable, a key feature allows the chemist to quickly undo changes to the ligand with a single mouse click and get back to the original ligand. Once the chemist has designed a ligand they are happy with, it can be saved in a single file to share with colleagues. The editor is a perfect tool for communication among scientists and can aid brain-storming session in an exciting way because hypotheses can be tested instantaneously.

The ligand editor has many advanced functions that make use of MolSoft's much acclaimed ICM technology, which is the backbone of the tool. Inside the editor, features such as ligand minimization, docking, atom tethering and virtual screening are available to use. For example, thousands of chemical groups can be screened on a particular point of the ligand resulting in a ranked list of complexes. The editor can also be used for fragment based drug design and optimization. According to Professor Ruben Abagyan, MolSoft Founder and professor at the Scripps Research Institute, "This new interactive environment for lead discovery combines the best practices in flexible docking and interactive modeling. The user-friendly environment changes the way chemical probes are discovered in industry and academia. Furthermore, the freely available ICM Browser and ActiveICM plugin allow scientists to disseminate data among chemists and biologists in an interactive way."

The ICM 3D Ligand Editor is part of the ICM-Chemist-Pro software product available from MolSoft LLC (www.molsoft.com).


6.4.2009 New Feature: Display Alignment Profile

Click to enlarge image.

A popular request from the biologists who use ICM is to develop a way to visualize sequence conservation in an alignment. Therefore in ICM version 3.6-1e (to be released soon) we have developed a way to display the sequence profile in a multiple sequence alignment. The consensus strength of a residue at a point in the alignment is visually represented by the size of the letter in the profile (see accompanying image).

To display the sequence profile:


5.29.2009 MolSoft's ICM delivers star performance in GPCR modeling and docking competition.

Modeling structures of G Protein Coupled Receptors (GPCRs), the most prevalent drug targets, has always been a great challenge. Predicting how and where the drugs bind to those receptors is an even greater challenge. Until recently only bovine rhodopsin and beta 2 adrenergic receptor structures have been solved. Yet, when the structure of the Adenosin receptor A2a (the receptor for caffeine) was solved in a complex with a drug, the crystallographers annouced a challenge for all modellers and dockers to predict the binding interactions of the drug with the receptor.

60 groups have registered for the competition and 29 dared to submit their models. Up to 10 models were allowed to be submitted. More importantly the models were supposed to be ranked since usually only the top predicted pose is further pursued.

In a recent paper by Michino et al published in Nature Reviews the results are published (click here to read the paper). Two teams from Molsoft, Katrich-Abagyan and Lam-Abagyan built the models that had the largest number of correct ligand-receptor interatomic contacts, 45 and 34 out of 70, respecitvely out of all participants. Moreover, both models were ranked number 1, while the prediction from a competing modeler thathad better drug RMSD (when a flexible drug ring was considered) was only ranked 2. The fourth model from the Baker/Rosetta group had only 18 of correct contacts and this pose was only ranked 4th.

The ICM-based GPCR modeling approach employs the Ligand-guided principle and the ICM global optimization algorithm, and its success in ligand docking shows applicability of the method to a large class of problems in the field of GPCR drug discovery.


5.15.2009 New Feature: Accent Graphics

New ICM Publication : Type-II Kinase Inhibitor Docking, Screening, and Profiling Using Modified Structures of Active Kinase States. Kufareva and Abagyan J. Med Chem

Download the paper here.

Abstract:Type-II kinase inhibitors represent a class of chemicals that trap their target kinases in an inactive, so-called DFG-out state, occupying a hydrophobic pocket adjacent to the ATP binding site. These compounds are often more specific than those that target active DFG-in kinase conformations. Unfortunately, the discovery of novel type-II scaffolds presents a considerable challenge, partially because the lack of compatible kinase structures makes structure-based methods inapplicable. We present a computational protocol for converting multiple available DFG-in structures of various kinases (?70% of mammalian structural kinome) into accurate and specific models of their type-II bound state. The models, described as deletion-of-loop Asp-Phe-Gly-in (DOLPHIN) kinase models, demonstrate exceptional performance in various inhibitor discovery applications, including compound pose prediction, screening, and in silico activity profiling. Given the abundance of the DFG-in structures, the presented approach opens possibilities for kinome-wide discovery of specific molecules targeting inactive kinase states.

Floating Licenses for the Mac

Due to customer demand we now offer floating licenses for the Mac platform. A floating license is placed on a server and any client computer connected to the server can “check out” the license. In the past all ICM licenses for Mac were locked to a particular machine (nodelocked license). The floating license option now gives you more flexibility in your ICM use if you need it. You can receive a floating license for Mac the next time you renew or purchase a new license.

New Features in the Latest ICM Version

The new ICM developments are listed in the Release Notes here. In particular please see:

ICM Power Tip: Chemical searching very large databases.

ICM tables are capable of storing tens of thousands records. However, some problems operate with data sets so large that they do not fit in computer's memory. To work with such large amounts of data ICM uses the concept of Molsoft database (MOLT) files. Unlike many other table file formats, such as SDF, CSV and others, database files are optimized for fast search and other operations, like unique entry addition and diverse subset selection. To learn how to make a MOLT file and search see here.

New Features in the Latest ICM Release 3.6

Fully Interactive 3D Ligand Editor

The ligand editor is a powerful tool for the interactive design of new lead compounds in 3D. It allows you to make modifications to the ligand and see the affect of the modification on the ligand binding energy and interaction with the receptor. You can eidt the ligand by adding new functional groups, sampling a large collection of fragments on the fly, edit atoms or bonds, and and then in seconds see the affect of these changes on ligand binding. Clashes with the receptor are clearly flagged and energy contributions of each atom and total bidning energy and binding score are provided. Please see the graphical user interface manual for more information and instructions http://www.molsoft.com/gui/ligand-editor.html

Docking a Markush Library

Generate a Markush library and dock a focused version of it on the fly. See this example, optimizing the roscovitine ligand bound to CDK5 http://www.molsoft.com/gui/markush-docking.html

04.08.08 New ICM Paper: New method for the assessment of all drug-like pockets across a structural genome.

Nicola G, Smith CA, Abagyan R. New method for the assessment of all drug-like pockets across a structural genome. Comput Biol. 2008 Apr; 15(3):231-40.

Department of Molecular Biology, The Scripps Research Institute, La Jolla, California.

Abstract: With the increasing wealth of structural information available for human pathogens, it is now becoming possible to leverage that information to aid in rational selection of targets for inhibitor discovery. We present a methodology for assessing the drugability of all small-molecule binding pockets in a pathogen. Our approach incorporates accurate pocket identification, sequence conservation with a similar organism, sequence conservation with the host, and structure resolution. This novel method is applied to 21 structures from the malarial parasite Plasmodium falciparum. Based on our survey of the structural genome, we selected enoyl-acyl carrier protein reductase (ENR) as a promising candidate for virtual screening based inhibitor discovery.

03.20.08 New ICM Publication: A new method for ligand docking to flexible receptors

New ICM publication by the Scripps Research Institute and MolSoft scientists. See: Bottegoni G, Kufareva I, Totrov M, Abagyan R. A new method for ligand docking to flexible receptors by dual alanine scanning and refinement (SCARE). J Comput Aided Mol Des. 2008 Feb 14;

Paper link:

Abstract Protein binding sites undergo ligand specific conformational changes upon ligand binding. However, most docking protocols rely on a fixed conformation of the receptor, or on the prior knowledge of multiple conformations representing the variation of the pocket, or on a known bounding box for the ligand. Here we described a general induced fit docking protocol that requires only one initial pocket conformation and identifies most of the correct ligand positions as the lowest score. We expanded a previously used diverse "cross-docking" benchmark to thirty ligand-protein pairs extracted from different crystal structures. The algorithm systematically scans pairs of neighbouring side chains, replaces them by alanines, and docks the ligand to each 'gapped' version of the pocket. All docked positions are scored, refined with original side chains and flexible backbone and re-scored. In the optimal version of the protocol pairs of residues were replaced by alanines and only one best scoring conformation was selected from each 'gapped' pocket for refinement. The optimal SCARE (SCan Alanines and REfine) protocol identifies a near native conformation (under 2 A RMSD) as the lowest rank for 80% of pairs if the docking bounding box is defined by the predicted pocket envelope, and for as many as 90% of the pairs if the bounding box is derived from the known answer with approximately 5 A margin as used in most previous publications. The presented fully automated algorithm takes about 2 h per pose of a single processor time, requires only one pocket structure and no prior knowledge about the binding site location. Furthermore, the results for conformationally conserved pockets do not deteriorate due to substantial increase of the pocket variability.

03.03.08 New Review Article from MolSoft on Flexible Docking

Here is a link to a new publication in Current Opinion Structural Biology on flexible docking by Dr. Totrov (MolSoft) and Prof. Abagyan (Scripps). The paper highlights all the recent development for including multiple receptor conformations in docking to represent ligand induced fit.

Click here for a new tutorial on how to make a mutation in a protein structure and optimize.

02.14.08 MolSoft Scientists Collaborate with Schering Plough to Identify New GPCR Inhibitors using ICM.

Click here to read how MolSoft and Schering Plough scientists identified new inhibtitors for a GPCR using MolSoft's drug discovery products. The structure-based development of MCH-R1 and other GPCR antagonists is hampered by the lack of an available experimentally determined atomic structure. A ligand-steered homology modeling approach has been developed (where information about existing ligands is used explicitly to shape and optimize the binding site) followed by docking-based virtual screening. Top scoring compounds identified virtually were tested experimentally in an MCH-R1 competitive binding assay, and six novel chemotypes as low micromolar affinity antagonist "hits" were identified. This success rate is more than a 10-fold improvement over random high-throughput screening, which supports our ligand-steered method. Clearly, the ligand-steered homology modeling method reduces the uncertainty of structure modeling for difficult targets like GPCRs.

02.04.08 New Tutorial: How to dock to multiple receptor conformations.

There is a new tutorial online here

The tutorial uses Aldose Reductase as an example. Aldose Reductase has a flexible loop in the ligand binding pocket vicinity which enables a variety of inhibitors to bind and therefore in order to identify these ligands via docking it is necessary to sample the conformations of this loop and dock to an ensemble of structures.

June 16, 2003 Molsoft LLC Receives Phase II STTR Grant Award to Continue Developing Thyroid Receptor Antagonists

Molsoft LLC received a Phase II STTR award from the National Institutes of Health, National Institute of Diabetes and Digestive and Kidney Diseases, for continuation of the "Rational Development of Thyroid Receptor Antagonists. project. In Phase I, Molsoft and its collaborators at the NYU School of Medicine and the NYU Department of Chemistry achieved proof of concept. Molsoft.s virtual ligand screening technology was used to discover 14 small molecule thyroid receptor antagonists displaying extreme structural diversity with IC50s ranging from 4 to 30 microM. Additionally, the test-case lead optimization scheme designed in Phase I based on generating focused virtual libraries of molecules easily amenable to organic parallel synthesis resulted in the rapid identification of second generation hits with IC50 in the nanomolar range. In Phase II, Molsoft and its NYU research partners propose to conduct full-scale optimization cycles of selected hits identified in Phase 1 in order to produce low nanomolar hits and to evaluate those hits using computational tools, in vitro characterization, and preliminary animal studies.

26 August 2002. Molsoft Conducts Training Course/ Workshop in La Jolla, CA

Molsoft conducted an intensive 2-day training course/workshop on the ICM suite of products at La Jolla, CA. The lecture and hands-on demonstrations covered topics of interest to computational chemists and biologists in the area of drug discovery. The topics included molecular graphics, animation, bioinformatics, homology, protein modeling, docking and ICM command language for expert users.

The attendance was international with scientists coming from Asia and Europe as well as from various parts of the US. The attendees were interested in having future courses, both at the basic and at the advanced levels.

One of the attendees from Australia who is very well known in the modeling field for his early work in structural bioinformatics, Dr. Jiri Novotny (Consultant for Biocomputing and Bioinformatics), said, "The course was well organized and presented the participants with two full days of new and efficient tools applicable to the most pressing problems of current structural biology and bioinformatics: structural/functional annotation of genomic data, analysis of protein surfaces, ligand binding sites, virtual ligand screening, structure derivation, regularization and model building". He continued on to say, "Perhaps the most impressive aspect of the workshop was the skill, dedication and the highest professional standard of the scientific team established at Molsoft by Prof. Abagyan. In hands-on session at computer screens the participants were encouraged to ask questions and bring out problems that were answered and solved immediately by the whole team including themselves. It was an invaluable practice and a good demonstration of the speed and versatility of the newest ICM version."

The new version, ICM 3.0, was introduced at the course and was well accepted as an extremely user-friendly interface by the attendees. This version, which also has stereo viewing mode that works with VRex glasses on Linux and Windows platforms, was welcomed by all the participants as an efficient and low cost alternative to existing stereo viewing tools.

About the training course, Dr. Maxim Totrov, co-founder and Principal Scientist at Molsoft said, "The course provided us with a vital opportunity to meet members of the growing community of ICM-users and bring them up-to date with the latest developments in ICM. It was exciting to see first-time users perform complex molecular modeling tasks such as protein-ligand docking after only a few hours of training. These workshops are geared towards helping our customers utilize fully the power of ICM molecular modeling suite in their everyday work."
