  Antibacterial activity of substituted 5-methylbenzo[c]phenanthridinium derivatives

  摘要：

  Antibiotic resistance has prompted efforts to discover antibiotics with novel mechanisms of action. FtsZ is an essential protein for bacterial cell division, and has been viewed as an attractive target for the development of new antibiotics. Sanguinarine is a benzophenanthridine alkaloid that prevents cytokinesis in bacteria by inhibiting FtsZ self-assembly. In this study, a series of 5-methylbenzo[c]phenanthridinium derivatives were synthesized and evaluated for antibacterial activity against Staphylococcus aureus and Enterococcus faecalis. The data indicate that the presence of a 1- or 12-phenyl substituent on 2,3,8,9-tetramethoxy-5-methylbenzo[c]phenanthridinium chloride significantly enhances antibacterial activity relative to the parent compound or sanguinarine.

• A common and general access to berberine and benzo [c] phenanthridine alkaloids

  日期：1992.1

  The S(RN)1 reactions between o-iodobenzamides and the enolate anion from 2-acetyl homoveratric acid lead to key tricyclic compounds which are easily converted to either berberine or benzo [c] phenanthridine ring systems providing thus a high-yielding and versatile access to both classes of alkaloids.
