    使用蛋白质晶体结构设计胸苷酸合酶抑制剂:一类新的5-取代的喹唑啉酮的合成和生物学评价。
    摘要:
    描述了新型胸苷酸合酶(TS)抑制剂的设计,合成和生物学评估。通过对蛋白质-配体结构的重复晶体学分析来进行分子设计。在该项目开始时,我们专注于大肠杆菌TS,5'-氟脱氧尿酸(5-FdUMP)和经典的含谷氨酸叶酸类似物的高分辨率三元晶体复合物的叶酸辅因子结合位点。一种新型化合物的初步三元晶体结构已成功解决。通过分析该初始复合物,进行了进一步的结构修饰,并开发了一系列活性5-(芳硫基)喹唑啉酮。合成策略基于各种芳基硫代阴离子置换喹唑啉酮5位上的卤素。测试化合物对纯化的大肠杆菌和/或人TS的抑制作用,并在体外测定针对三种肿瘤细胞系的细胞毒性。用几种抑制剂观察到了重要的胸腺嘧啶核苷保护作用,表明TS是细胞内活性位点。
