N-[4-1-Hydroxy-3-(2-amino-4-hydroxy-5,6,7,8-tetrahydropyrido[2,3-d]pyrimid in-6-yl)prop-2-yl )benzoyl]-glutamic acid, it salts, and derivatives thereof, have an inhibitory effect on one or more enzymes which utilize folic acid and can be used, alone or in combination, to inhibit the growth of those neoplasms which otherwise depend upon the enzymes so inhibited. The compounds can be prepared through catalytic hydrogenation of a protected derivative of N-[4-1-hydroxy-3-(2-amino-4-hydroxy-pyrido[2,3-d]pyrimidin-6-yl)prop-2-en -2-yl)benzoyl]glutamic acid and removal of the protecting groups.
N-[4-1-羟基-3-(2-氨基-4-羟基-5,6,7,8-四氢吡啶[2,3-d]嘧啶-6-基)丙-2-基)苯甲酰]-谷氨酸,其盐及其衍生物,对利用叶酸的一个或多个酶具有抑制作用,并可单独或结合使用,以抑制那些依赖被抑制酶的肿瘤的生长。这些化合物可以通过对N-[4-1-羟基-3-(2-氨基-4-羟基-吡啶[2,3-d]嘧啶-6-基)丙-2-烯-2-基)苯甲酰]谷氨酸的保护衍生物进行催化氢化和去除保护基来制备。
