QSAR: Then and Now

Abstract: In this review, the evolution of QSAR is traced from the insightful observations of Crum-Brown and Frazier to Hammett's critical equations and finally Hansch's seminal contributions on hydrophobicity and modelling of biological activity based on extrathermodynamic principles. Today's QSAR models can stand alone, augment other graphical approaches or be examined in tandem with equations of a similar mechanistic genre to truly reveal the power of the paradigm. This review will focus on the three standard classif… Show more

“…The three standard classifications routinely used in QSAR analysis: electronic, hydrophobic and steric including topological indices are invaluable in helping to delineate a large number of receptor-ligand interactions that are critical to biological processes [16]. QSAR models can stand alone, augment other modeling approaches or be examined in tandem with equations of a similar mechanistic genre to establish authenticity and reliability [18].…”

“…Appropriate representation of the structural and physicochemical features of chemical agents is an essential key to the successful application of quantitative structure-activity relationship (QSAR) models [1][2][3][4][5] and to the elucidation of the underlying molecular mechanism of a particular biological activity from the derived statistical models. Therefore, finding different molecular descriptors including two-dimensional (2D) and three-dimensional (3D) parameters with higher correlation toward activity/property is in the frontier of QSAR/QSPR researches.…”
