  名称：

  Anti-mycobacterial, cytotoxic activities of Knoevenagel and (E)-α,β-unsaturated esters and ketones from 2-chloronicotinaldehydes

  摘要：

  Series of 2-chloronicotinaldehyde Knoevenagel derivatives 3a-r; (E)-alpha,beta-unsaturated esters and ketones 5a-k were prepared and evaluated for their in vitro anti-mycobacterial activity against Mycobacterium tuberculosis H(37)Rv (Mtb). Compounds 3e, 5b, 5d, 5e, 5g and 5i-k were shown potent to significant activity. Compound 5j is the most potent Mtb inhibitor (MIC: 4.89 mu M) when compared to standard drugs Ethambutol (MIC: 7.63 mu M) and Ciprofloxacin (MIC: 9.44 mu M). Eight compounds displayed potent/significant activity against M. tuberculosis were chosen for the cytotoxicity against three cell lines (Raw 264.7, MCF7, and HeLa). Compound 5j displayed low toxicity with high selective index (15-30) and is an interesting new compound may serve for the development of therapeutics targeted against anti-mycobacterial compounds. This is the first report assigning in vitro anti-mycobacterial inhibitory activity and structure-activity relationship for this class of substituted 2-chloronicotinaldehyde derivatives and presents new family of compounds.
