New method for rapid characterization of molecular shapes: applications in drug design

Abstract

We present a method for the rapid quantitative shape match between two molecules or a molecule and a template, using atom triplets as descriptors. This technique can be used either as a rapid screen preceding the computationally expensive shape-based docking method developed by Kuntz and co-workers or as a stand-alone method to rank compounds in a large database for their fit to a shape template. The merits and limitations of this method are discussed in detail with examples.
