  Synthesis and SAR of bicyclic heteroaryl hydroxamic acid MMP and TACE inhibitors

  摘要：

  Potent and selective bicyclic heteroaryl hydroxamic acid MMP and TACE inhibitors were synthesized by a novel convergent route. Selectivity and efficacy versus MMPs and TACE could be controlled by appropriate substitution on the scaffolds and by variation of the P1' group. Select compounds were found to be effective in in vivo models of arthritis. (C) 2003 Elsevier Science Ltd. All rights reserved.

  3-（苯并[d]噻唑-2-基）-4-氨基喹啉衍生物通过DNA嵌入作为新型支架拓扑异构酶I抑制剂：设计，合成和抗肿瘤活性

  摘要：

  已经设计并合成了二十七个3-（苯并[ d ]噻唑-2-基）-4-氨基喹啉衍生物作为拓扑异构酶I抑制剂。在体外针对四种人类肿瘤细胞系（MGC-803，人肝癌HepG-2，T24，和NCI-H460）和一个正常细胞系的抗增殖评价（HL-7702）表示，其中大部分表现出强的细胞毒性。其中，5a被认为是最有前途的候选物，其IC 50值低至约2.20±0.14，并被选作进一步探索。光谱分析和琼脂糖凝胶电泳分析表明5a可以与DNA相互作用并强烈抑制拓扑异构酶I（Topo I）。进一步筛选化合物5b的Topo I活性，5c，5e，5f，5h，5i，5j，5l和5n表明一些化合物可能与5a具有完全不同的细胞毒性。分子建模研究证实5a采用独特的模式与DNA和Topo I相互作用。其他分子机理研究表明，用5a处理MGC-803细胞可诱导S期阻滞，上调促凋亡蛋白，下调抗凋亡蛋白，激活caspase-3，随后诱导

  groups from oxyarene N-heterocycles at positions capable for 2-/4-O-pyridine–2-/4-pyridone tautomerism. Blue light irradiation, a [Ru] or [Ir] photocatalyst, and ascorbic acid in a water–acetonitrile solution debenzylates a variety of aryl N-heterocycles cleanly and selectively. Ascorbic acid has two functions in the reaction. On the one hand, it protonates the N-heterocycles that reduces their reduction
