A new series of 2-morpholine-piperidine-pyrrolidine substituted quinoline based chalcones have been synthesized by conventional and microwave irradiation methods. All synthesized compounds were characterised by IR, 1 H and 13 C NMR, mass spectrometry, and elemental analysis. The products were evaluated in vitro for antibacterial activity against two bacterial strains (Staphylococcus aureus, Escherichia coli) and antifungal activity against two fungal strains (Aspergillus flavus, Candida metapsilosis). 2-Piperidine substituted quinoline chalcones demonstrated high antimicrobial activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
