Exploring Structural and Physicochemical Profiles of Potential GSK-3β Inhibitors using Structure- and Ligand-based Modeling Studies. Comb Chem High Throughput Screen. 2016 Apr 11; Authors: Hossain T, Saha A, Mukherjee A Abstract Glycogen synthase kinase-3β (GSK-3β) is a promising target for therapeutic invasion of Alzheimer's disease (AD). The kinase enzyme plays major role in pathological process for the formation of β-amyloid plaques and neurofibrillary tangles in AD. In the present study, structure-based pharmacophore and ligand-based 3D QSAR, HQSAR and pharmacophore mapping studies have been emphasized to explore the possible structural requirement of this potential kinase inhibitors using a structurally diverse set of compounds. The developed models were validated with the interaction study at the catalytic cleft. The 3D QSAR studies yield robust models of CoMFA R2 = 0.965, se = 0.212, Q2 = 0.525, R2pred = 0.709, r2m = 0.579 and CoMSIA: R2 = 0.935, se = 0.289, Q2 = 0.581, R2pred = 0.723, r2m = 0.935, that explain the importance of steric, electrostatic, hydrogen bond (HB) acceptor of the molecule for inhibition of GSK-3β. The HQSAR study (R2 = 0.871, se = 0.400, Q2 = 0.639, R2pred = 0.721, r2m = 0.664) indicated the fragments of the molecular fingerprints that might be important for inhibition. Both structure- and ligand-based pharmacophore mapping proposed that acceptor and donor features of the molecule are essential for ...
