  Crystal-structure-based design and synthesis of benz[cd]indole-containing inhibitors of thymidylate synthase

  摘要：

  The X-ray crystal-structure-based design, synthesis, and biological activity of a novel family of benz[cd]indole-containing inhibitors of thymidylate synthase (TS) are described. The structure-activity of the lead compound was studied by conceptually dividing the molecule into four regions and independently optimizing the substituents for each region. Combination of favored substituents for each region led to inhibitors with K(i)'s against the human enyzme in the range of 10-20 nM. Thymidine shift experiments suggested that the cytotoxic properties of the best enzyme inhibitors were due to TS targeting in cells. The inhibitors were synthesized from substitued 6-aminobenz[cd]indol-2(1H)-ones by alkylation with both a simple alkyl group and a substituted benzylic portion. The 2,6-diaminobenz[cd]indoles were prepared from the corresponding lactams by conversion to the thiolactam, alkylation to the methylated thiolactam, and then displacement with a substituted or unsubstituted amine.

  Antifolate inhibitors of thymidylate synthase (TS) have primarily been based on the structure of folic acid. This paper describes the identification and development of novel 6,7-imidazotetrahydroquinoline TS inhibitors by iterative ligand design, synthesis, and crystallographic analysis of protein-inhibitor complexes. Beginning with a high-resolution crystal structure of E. coli TS (TS, EC 2.1.1.45)

  胸苷酸合酶（TS）的抗叶酸抑制剂主要基于叶酸的结构。本文通过蛋白质配体复合物的迭代配体设计，合成和晶体学分析描述了新型6,7-咪唑四氢喹啉TS抑制剂的鉴定和开发。从大肠杆菌TS（TS，EC 2.1.1.45）的高分辨率晶体结构开始，从头设计了咪唑四氢喹啉抑制剂以占据叶酸结合袋。然后根据来自其他共晶体结构和活性数据的反馈，对初始化合物1h（Ki约为5 microM人/大肠杆菌TS）进行结构修饰。发现在咪唑的2-位上的氨基将系列的效力提高1-2个数量级。咪唑环上的其他取代基（1-CH3、2- 、2-NH 、2-S ）通常会导致抑制作用减弱。通过修饰四氢喹啉氮上的取代基，使三种化合物的Ki对人TS酶的作用低于15 nM，可以进一步提高活性。测试了这些化合物的细胞毒性，并显示了它们在体外能抑制三种肿瘤细胞系的生长。
