  描述：

  ethyl 7-cyclopropyl-2-(4-methoxyphenyl)-3-nitro-4-oxo-4,7-dihydrothieno[2,3-b]pyridine-5-carboxylate 在 亚磷酸三乙酯 作用下， 反应 1.75h， 以40%的产率得到ethyl 1-cyclopropyl-7-methoxy-4-oxo-1,5-dihydro-4H-pyrido[3',2':4,5]thieno[3,2-b]indole-3-carboxylate

  名称：

  Synthesis and biological evaluation of tetracyclic thienopyridones as antibacterial and antitumor agents

  摘要：

  A facile synthesis of model 4-oxopyrido[3',2':4,5]thieno[3,2-b]indole-3-carboxylic acids 9a-e was achieved via Stille arylation of 2-chloro-3-nitro-4-oxothieno[2,3-b]pyridine-5-carboxylate and a subsequent microwave-assisted phosphite-mediated Cadogan reaction. The new compounds were tested for their in vitro antimicrobial and antiproliferative activity. Compounds 9a-c and 9e exhibited very high potency against Gram positive Bacillus subtilis and Bacillus megaterium at concentrations 0.000015-0.007 mu g/mL. They also displayed excellent activity towards other Gram positive bacilli and staphylococci and Gram negative Haemophilus influenzae, being in most cases superior or equal to commercial fluoroquinolones. Both 9a and 9c were inhibitors of the DNA gyrase activity. As concerns antitumor properties, compounds 9b-e showed growth inhibition of MCF-7 breast tumor and A549 non-small cell lung cancer cells with IC50 1.6-2.8 mu M and 2.6-6.9 mu M, respectively, coupled with absence of cytotoxicity towards normal cells. These compounds are promising as dual acting chemotherapeutics. (C) 2011 Elsevier Ltd. All rights reserved.
