Synthesis and antimicrobial activity of some new 2-indolinone derived oximes and spiro-isoxazolines

Abstract

The synthesis and spectral analysis of some new 1,3-dihydro-3-hydroxy-3-[2-hydroxyimino-2-(substituted phenyl)ethyl]-2H-indol-2-ones (21–32) and spiro[3H-indol-3,5/t’-(4/t’H)-isoxazol]-2(1H)-ones (33–44) are described. Sixteen of the synthesized compounds were screenedin vitro for their growth inhibitory activity against thirteen species of microorganisms,viz, S. aureus, S. epidermidis, S. faecalis, B. subtilis, B. cereus, E. aerogens, E. coli, P. aeruginosa, P. vulgaris, A. baumonia, A. faecalis, C. albicans andS. cervicae. Most of the compounds exhibited significant antimicrobial activity especially the oximes28 and29.
