Abstract

The analysis of structure-activity relationships started probably more than hundred years ago but the concept of quantitatively correlating physicochemical properties of molecules with their biological activities, termed as quantitative structure-activity relationship (QSAR), was initiated by Corwin Hansch and his groups in early 1960. Many new methods have emerged since then. The concept evolved from 2D QSAR to 3D QSAR and lately another dimension (4D QSAR) has been added. This evolution is briefly reviewed here.

Keywords: quantitative structure-activity relationship (QSAR), Hologram QSAR, Inverse QSAR, Binary QSAR, QSAR METHODS
