  Synthesis and biological evaluation of tetracyclic fluoroquinolones as antibacterial and anticancer agents

  摘要：

  A simple and efficient synthesis of 6-fluoro-4-oxopyrido[2,3-a] carbazole-3-carboxylic acids (13a-e) and a structurally related 6-fluoro-4-oxothieno[2 ',3 ': 4,5] pyrrolo[3,2-h] quinoline (13f) was achieved via Stille arylation of 7-chloro-6-fluoro-8-nitro-4-oxoquinoline-3-carboxylate and a subsequent microwave-assisted phosphite-mediated Cadogan reaction. The new compounds were tested for their in vitro antimicrobial and antiproliferative activity. The ability of 13a-f to inhibit the activity of DNA gyrase and topoisomerase IV was also investigated. The thieno isostere (13f) emerged as the most active antibacterial, while the 9-fluoro derivative (13e) was the most potent against multidrug-resistant staphylococci. Compounds 13a, 13c-f displayed growth inhibition against MCF-7 breast tumor and A549 non-small cell lung cancer cells coupled with an absence of cytotoxicity toward normal human-derm fibroblasts (HuDe). Compound 13e was the most active anticancer against MCF-7 cells, with greater potency than ellipticine (IC50 0.8 and 1.6 mu M, respectively). The most active compounds in this series show promise as dual acting anticancer and antibacterial chemotherapeutics. (C) 2010 Elsevier Ltd. All rights reserved.
