Recent Advances in the Assessment of Druglikeness Using 2D-Structural Descriptors

Hariharan Rajesh, Lakshminarasimhan Rajagopalan and Vellarkad N. Viswanadhan

Abstract

A review of methods employed for the assessment of druglikeness using 2D structural and atom type descriptors is presented. These methods are classified as Druglike Filters (DLFs) and Druglike Indices (DLIs), depending on the characterization of druglikeness, using known drug and non-drug databases. The DLF methods specify a set of rules based on calculated property distributions, whereas the DLI methods aim to assess druglikeness through a single number derived from multiple descriptors. A review of ranges calculated from property profiles of known drugs is given, along with a careful re-assessment for twenty five descriptors based on an analysis of a recent drug database. A discussion of future direction for the development and utility of these approaches is presented.
