Synthesis of new olefin chalcone derivatives as antitumor, antioxidant and antimicrobial agents

Abstract

Chalcone is a unique template that is associated with several biological activities. Claisen–Schmidt condensation of olefin aldehyde 3 and various mono, disubstituted and heterocyclic acetophenones afforded novel olefin chalcones. Synthesized compounds were subjected for ADME prediction by computational method which revealed that these molecules can be considered as a potential drug. Out of the 21 compounds screened, compounds 5u, 5g, 5c and 5e have shown significant cytotoxicity against Hep 3BPN 7, compounds 5j, 5i, 5n and 5o showed good cytotoxicity against HL 60 P 58. Compounds 5f, 5c, 5e and 5b showed potent cytotoxicity against Hela B 75. Antioxidant activity was assessed using three methods, namely, 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl radical scavenging and ferric reducing antioxidant power (FRAP). The result shows that all these compounds possess significant antioxidant activity. Compounds 5k, 5s, 5a and 5c showed promising antibacterial activity. Compounds 5k, 5u and 5f could be considered as chemopreventive agents.
