OCF3 greater than or equal to F. The 2-desamino target compounds 13a-c,k also exhibited significant, although diminished, TS inhibition. Both series were growth inhibitory to cells in tissue culture and this inhibition could be reversed by thymidine alone, indicating that the primary target was TS. None of the compounds was a potent inhibitor of dihydrofolate reductase. These studies indicate that the
描述了两个系列的非经典胸苷酸合酶(TS)抑制剂的合成和生物学活性。第一个是一系列10-炔丙基-5,8-二叠氮基水杨酸衍生物(10a-j),第二个是一系列类似的2-desamino衍生物(13a-c,k),两者在其上均具有更亲脂的取代基苯环比经典抗叶酸剂的CO-谷氨酸盐高。化合物10a-j通常以各种方式处理N- [6-(溴甲基)-3,4-二氢-4-氧代-2-喹唑啉基] -2,2-二甲基丙酰胺(6),以直接的方式制备。苯基取代的N-炔丙基苯胺(8),然后脱保护。由[6-(溴甲基)-4-氧代-3(4H)-喹唑啉基] 2,2-二甲基丙酸甲酯(11)类似地制备化合物13a-c,k。测试了这些化合物对纯化的L1210 TS的抑制作用以及对L1210细胞的体外抑制作用。这些非经典类似物中的几种达到了含有谷氨酸的TS抑制剂10-炔丙基-5,8-二氮杂az酸(1,CB3717)的TS抑制能力。2-氨基目标化合物10a-j通常是L1210
