PHASE: A Novel Approach to Pharmacophore Modeling and 3D Database Searching

Abstract

Pharmacophore modeling and 3D database searching are now recognized as integral components of lead discovery and lead optimization, and the continuing need for improved pharmacophore‐based tools has driven the development of PHASE. By employing a novel, tree‐based partitioning algorithm, PHASE exhaustively identifies spatial arrangements of functional groups that are common and essential to the biologic activity of a set of high affinity ligands. These pharmacophore hypotheses are validated in a number of ways, including their ability to: (i) rationalize the binding affinities of a training set of molecules of varying activity, (ii) successfully predict the affinities of a test set of molecules, and (iii) selectively retrieve known actives from a database of drug‐like molecules. In addition, PHASE uniquely offers the ability to distinguish multiple binding modes through a bi‐directional clustering approach applied to bit string representations of the ligand/hypothesis space.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
