Synthesis and QSAR studies of 4-substituted phenyl-2,6-dimethyl-3, 5-bis-N-(substituted phenyl)carbamoyl-1,4-dihydropyridines as potential antitubercular agents.

Synthesis and QSAR studies of the title compounds have resulted in the identification of structural and physicochemical parameters (MR, sigma(o), sigma(m), sigma(p)) contributing to antitubercular activity. Among these, carbamoyl phenyl ring substituted at 3 and 4 position with NO(2) group or 2 position with Cl or OCH(3) group shows >90% inhibition against H(37)Rnu comparable to other substituted phenyls.
