Studies on synthesis and evaluation of quantitative structure–activity relationship of 5-[(3′-chloro-4′,4′-disubstituted-2-oxoazetidinyl)( N-nitro)amino]-6-hydroxy-3-alkyl/aryl[1,3]azaphospholo[1,5- a]pyridin-1-yl-phosphorus dichlorides

Abstract

A new series of 5-[(3′-chloro-4′,4′-disubstituted-2-oxoazetidinyl)( N-nitro)amino]-6-hydroxy-3-alkyl/aryl[1,3]azaphospholo[1,5- a]pyridin-1-yl-phosphorus dichlorides has been synthesized and subjected to acute antibacterial and antifungal screening studies. All the derivatives belonging to this series delineated remarkable activity as compared to standard drugs (ampicillin and clotrimazole). Compounds are quantitatively analyzed in relation to their different physicochemical parameters. Significant correlations were obtained between biological activity and polarizability parameter (MR).
