A Quantitative Structure - Activity Relationship Analysis Of Some Substituted Oxazolopyridines And Benzimidazoles With Antiinflammatory Activity

Author(s): S. K Chakravarti, S. C Chaturvedi

The lowest energy conformations of some antiinflammatory 2-(substituted phenyl) oxazolopyridines, 2-(substituted pyridinyl) benzimidazoles and 1H-benzimidazoles were calculated and quantitative structure-activity relationship analysis was then performed on each category of compounds using thermodynamic, electronic and spatial descriptors. The resulting QSAR equations were validated by leave-one-out cross validation method. Electronic parameter (dipole moment) and spatial parameters (molecular volume and principal moment of inertia) were found to have significant correlationship with antiinflammatory activity.
