Synthesis and biological evaluation of beta-chloro vinyl chalcones as inhibitors of TNF-alpha and IL-6 with antimicrobial activity.


PMID 20171758

Abstract

A series of beta-chloro vinyl chalcones have been synthesized by Claisen-Schmidt condensation. beta-chloro vinyl aldehyde has been synthesized by the Vilsmayer-Hack formylation reaction. The structures of the newly synthesized compounds were confirmed by 1H NMR, IR and Mass spectral analysis. All the compounds were evaluated for their anti-inflammatory activity (against TNF-alpha and IL-6) and antimicrobial (antibacterial and antifungal) activity. Compounds 5a, 5d, 5e, 5g and 5i exhibited promising activity against IL-6 with 58-83% inhibition at 10 microM concentration. None of the compound was found to be cytotoxic in CCK-8 cells at 10 microM concentration. Whereas compounds 5b, 5d, 5e and 5i showed very good antibacterial activity and compounds 5a, 5b, 5e and 5i showed good antifungal activity.
