Abstract

Some 2,6-diarylpiperidin/tetrahydrothiopyran/tetrahydropyran-4-one oximes were synthesized in dry media under microwave irradiation and were evaluated for their in vitro antibacterial activity against clinically isolated bacterial strains i.e. S.aureus, β-H.Streptococcus, E.coli, P.aeruginosa, S.typhii and in vitro antifungal activities against fungal strains i.e. C.albicans, Rhizopus, A.niger and A.flavus. Structure-activity relationships for the synthesized compounds showed that compounds 12 and 15 exerted excellent antibacterial activity against all the tested bacterial strains except 15 against S.aureus and β-H.streptococcus. Against C.albicans and A.flavus, compound 15 exerted potent antifungal activities while against Rhizopus, compound 16 showed promising activity.
