Several classical quinazoline analogues of folic acid bearing chloro or methyl substituents at position 5 were evaluated as inhibitors of the growth of four human gastrointestinal adenocarcinoma cell lines in vitro. The preparation of two of these, 5-chloro-5,8-dideazaisofolic acid, 1e, and 5-chloro-5,8-dideazaisoaminopterin, 2a, is reported for the first time. In addition, a new synthetic route to
几个经典的叶酸在5位带有氯或甲基取代基的喹唑啉类似物被评估为体外抑制四种人胃肠道腺癌细胞系生长的抑制剂。首次报道了其中的两种化合物,即5-氯-5,8-二叠氮杂异叶酸1e和5-氯-5,8-二叠氮杂异氨蝶呤2a的制备。另外,描述了合成5-氯-5,8-二叠氮基氨基蝶呤2b的新途径。对于具有2,4-二氨基构型的化合物,在位置5处存在氯提供了优异的生长抑制效能。但是,化合物1e的效力远不及其5-甲基类似物。
