The new folate antagonist, 5-fluoro-5,8-dideazaisoaminopterin was synthesized in four steps beginning with 2,4-diamino-5-fluoroquinazoline. It was found to be a potent inhibitor of human dihydrofolate reductase. Against L1210 leukemia in mice, 5-fluoro-5,8-dideazaisoaminopterin was equiactive with methotrexate at approximately one half of the total dose employed.
从2,4-二氨基-5-氟喹唑啉开始,分四个步骤合成了新的叶酸拮抗剂5-氟-5,8-二氮杂异氨基蝶呤。发现它是人二氢叶酸还原酶的有效抑制剂。针对小鼠中的L1210白血病,5-氟-5,8-二氮杂异氨基蝶呤与甲氨蝶呤的活性相等,约为所用总剂量的一半。
