The design, synthesis, and biochemical and biological evaluations of a novel series of 2,6-diaminobenz[cd]indole-containing inhibitors of human thymidylate synthase (TS) are described. The compounds are characterized by having either a pyridine or pyridazine ring in place of the (phenylsulfonyl)morpholinyl group of the known inhibitor N6-[4-(morpholinosulfonyl)benzyl]-N6-methyl-2,6-diaminobenz[ cd]indole
描述了一系列新型的含有2,6-二氨基苯并[cd]吲哚的人胸苷酸合酶(TS)抑制剂的设计,合成以及生化和生物学评估。所述化合物的特征在于具有吡啶或哒嗪环代替已知抑制剂N6- [4-(吗啉代磺酰基)苄基] -N6-甲基-2,6-二氨基苯并[cd]吲哚葡糖醛酸酯的(苯基磺酰基)吗啉基。 (一世)。该系列的活性化合物在低于10 nM的水平下显示出人类TS抑制常数,并且在细胞培养中是有效的选择性亚微摩尔抗肿瘤剂。通过取代的6-氨基苯并[cd]吲哚的还原烷基化或取代的1-氰基-8-硝基萘的还原环化合成这些化合物。
