Hansch analysis
WebThe first 3-D QSAR was named Comparative Molecular Field Analysis (CoMFA) by Cramer et al. It examined the steric fields (shape of the molecule) and the electrostatic fields [20] which were correlated by means of partial least squares regression (PLS). WebThe Hansch Analysis, also known by QSAR-2D, is an extremely effective tool in the identification and/or improvement of the pharmacological or toxicological profile of …

WebQSAR involves mainly physical chemistry and molecular docking tools (CoMFA and CoMSIA), that leads to tabulated data and first and second order equations. There are many theories, the most relevant being Hansch's analysis that involves Hammett electronic parameters, steric parameters and logP(lipophilicity) parameters.
Webelements (Free Wilson analysis), physicochemical properties (Hansch analysis), or fields (3D QSAR). Classical QSAR analyses (Hansch- and Free Wilson analyses) consider only 2D structures. Their main field of application is in substituent variation of a common scaffold. 3D-QSAR analysis (CoMFA) has a much broader scope. albuterol common doseWebThe Hansch analysis involves the development of a mathematical model which correlates the physicochemical parameters of molecules (lipophilic, electronic, steric and toplogical properties etc.) with their biological activity.
