2,4-Diamino- and 2-amino-4-hydroxy- derivatives of N-(4-[2-(pyrido[2,3-d]pyrimidin-6-yl)alkyl]benzoyl)-L-glutamic acids, and the corresponding 5,6,7,8-tetrahydro compounds are antineoplastic agents. The compounds are prepared by hydrolytic or hydrogenolytic removal of carboxylic acid protecting groups from the correspondingly protected glutamic acid derivatives. A typical embodiment is N-)4-[2-(2-amino-4-hydroxy-5,6,7,8-tetrahydropyrido[2,3-d]pyrimidin-6-yl)e thyl]benzoyl)-L-glutamic acid.
2,4-二氨基和2-氨基-4-羟基-N-(4-[2-(吡啶并[2,3-d]嘧啶-6-基)烷基]苯甲酰)-L-谷氨酸衍生物及其相应的5,6,7,8-四氢化合物是抗肿瘤剂。这些化合物是通过从相应保护的谷氨酸衍生物中水解或氢解羧酸保护基制备而成的。一个典型的实施例是N-)4-[2-(2-氨基-4-羟基-5,6,7,8-四氢吡啶[2,3-d]嘧啶-6-基)乙基]苯甲酰)-L-谷氨酸。
