  Synthesis, antimicrobial activity and possible mechanism of action of 9-bromo-substituted indolizinoquinoline-5,12-dione derivatives

  摘要：

  A series of 9-bromo-substituted indolizinoquinoline-5,12-dione derivatives was synthesized. Antimicrobial activity assessment indicates that compounds 1, 26, 27 and 28 exhibit strong activity against gram-positive bacterial strains, including Beta-hemolytic streptococcus CMCC32210, Staphylococcus aureus ATCC25923, Staphylococcus epidermidis ATCC12228, Enterococcus faecalis ATCC29212 and methicillin-resistant S. aureus ATCC43300 (MRSA). Compound 27 shows the best anti-MRSA activity with an MIC value of 0.031 mu g/ml. To assess the mechanism of action, the inhibitory activities of compound 1 against DNA gyrase and DNA topoisomerase IV were also measured. The results indicate that compound 1 has strong inhibitory effects on the Escherichia coli DNA gyrase supercoiling activity and S. aureus Topo IV relaxing activity. (C) 2011 Elsevier Masson SAS.
