The Atomic Property Fields (APF) superposition/alignment method was first reported by Maxim Totrov PhD (Principal Scientist - MolSoft) at the 2007 233rd American Chemical Society National Meeting, Chicago, IL USA and then published here.
APF is a 3D pharmacophoric potential implemented on a grid. 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).Here we describe template APF superposition whereby the APF is generated from a single or multiple template and is then globally optimized with the internal force-field energy of the ligand.
