Microwave-assisted synthesis and antibacterial activity of novel chenodeoxycholic acid thiosemicarbazone derivatives

Abstract

A rapid and efficient method for the synthesis of novel chenodeoxycholic acid thiosemicarbazone derivatives under solvent-free conditions using microwave irradiation is reported. Ten novel compounds have been synthesised in good yields. Their structures were elucidated by 1H NMR, IR, ESI-MS spectra and elemental analysis. Preliminary results showed that some of these compounds possess inhibitory effects against S. typhimurium and E. coli.
