  Synthesis and Biological Evaluation of 2-(Alkoxycarbonyl)-3-Anilinobenzo[b]thiophenes and Thieno[2,3-b]pyridines as New Potent Anticancer Agents

  摘要：

  Two new series of inhibitors of tubulin polymerization based on the 2-(alkoxycarbonyl)-3-(3',4',5'-trimethoxyanilino)benzo[b]thiophene and thieno[2,3-b]pyridine molecular skeletons were synthesized and evaluated for antiproliferative activity on a panel of cancer cell lines, inhibition of tubulin polymerization, cell cycle effects, and in vivo potency. Antiproliferative activity was strongly dependent on the position of the methyl group on the benzene portion of the benzo[b]thiophene nucleus, with the greatest activity observed when the methyl was located at the C-6 position. Also, in the smaller thieno[2,3-b]pyridine series, the introduction of the methyl group at the C-6 position resulted in improvement of antiproliferative activity to the nanomolar level. The most active compounds (4i and 4n) did not induce cell death in normal human lymphocytes, suggesting that the compounds may be selective against cancer cells. Compound 4i significantly inhibited in vivo the growth of a syngeneic hepatocellular carcinoma in Balb/c mice.

  苯环上给电子取代基取代的[1]苯并噻吩并[3,2- d ]嘧啶的合成

  摘要：

  将各种2-氟苄腈转化为相应的3-氨基[1]苯并噻吩羧酸酯，然后将其与甲am或各种等价物进行环化，生成所需的三环苯并噻吩并嘧啶。将各种甲氧基和硝基/氨基取代基置于苯环上，需要几种不同的策略来制备所需的苯并噻吩。还需要几种不同的嘧啶酮环化。还描述了在四步一锅式低温锂化过程中使用富电子的2-溴苄腈来生产高度富电子的氨基[1]苯并噻吩羧酸酯。7-氨基-8-氟[1]苯并噻吩并[3,2 - d ]嘧啶-4（3 H）的合成）-一种相对简单，但是合成相应的7-氨基-8-protio类似物非常困难，并且需要多种方法才能找到成功的方法。

  2-fluorobenzonitriles were converted to the corresponding 3-amino[1]benzothiophenecarboxylic acid esters, which in turn were annulated with formamidine or various equivalents to produce the desired tricyclic benzothienopyrimidines. Various methoxy and nitro/amino substituents were placed on the phenyl ring, requiring several different strategies to prepare the desired benzothiophenes. Several different pyrimidone annulations
