In Hansch analysis, a classical QSAR approach, relationships between chemical structure and biological activity are quantified using physicochemical descriptors like lipophilicity (log P, Hansch π), electronic (Hammett σ) and steric (Taft Es) parameters. B.Pharm students learn to construct Hansch equations using multiple regression, interpret coefficients (including parabolic π2 terms), assess model quality with r2, F-test … Read more

Introduction: QSAR (Quantitative Structure–Activity Relationship) uses physicochemical parameters to predict drug behavior. Key descriptors include the partition coefficient (log P) which measures lipophilicity and membrane permeability, Hammett’s constant (σ) that quantifies electronic (inductive and resonance) effects of aromatic substituents, and Taft’s steric parameter (Es) describing aliphatic steric hindrance. Understanding how log P, σ and Es … Read more
