QSAR studies on antimalarial substituted phenyl analogues and their Nω-oxides

A quantitative structure-activity relationship (QSAR) study on a series of substituted phenyl analogues 5-[(7-chloro-4-quinolinyl)amino]-3-[(alkylamino)methyl](1,1'-biphenyl)-2-ols and their N-omega-oxides was made using various combinations of electronic and topological parameters. Several statistically significant regression expressions were obtained using multiple regression analyses. These regressions may be considered as mathematical models for investigating antimalarial activities of the compounds under present study. The antimalarial activity mechanism was investigated using combinations Of E-L and E-H, independently with other molecular descriptors. (C) 2002 Elsevier Science Ltd. All rights reserved.
