The synthesis is described of a series of analogues of the potent thymidylate synthase (TS) inhibitor, N-[4-[N-[(3,4-dihydro-2, 7-dimethyl-4-oxo-6-quinazolinyl)methyl]-N-prop-2-ynylamino]-2-f luorob enzoyl]-L-glutamic acid (4, ZM214888), in which the glutamic acid moiety is replaced by homologous amino acids and alpha-amino acids where the omega-carboxylate is replaced by acylsulfonamides and acidic
描述了一系列有效的胸苷酸合酶(TS)抑制剂N- [4- [N-[(3,4-dihydro-2,7-二甲基-4-氧代-6-喹唑啉基)甲基]的类似物的合成] -N-丙-2-炔基氨基] -2-氟罗布烯基] -L-谷氨酸(4,ZM214888),其中谷氨酸部分被同源氨基酸和α-氨基酸取代,其中ω-羧酸盐被酰基磺酰胺和酸性杂环取代。通常,当与4比较时,这些修饰产生具有增强的效力的化合物,其作为分离的TS的抑制剂和对鼠肿瘤细胞系的细胞毒性剂。新化合物需要通过还原的叶酸载体运输才能进入细胞,但不能在细胞内转化为聚谷氨酸。由于叶酰聚谷氨酸合成酶的低表达,预期具有这种特征的药物显示出对经典抗叶酸具有抗性的肿瘤的活性。类似物(S)-2- [4- [N-[(3,4-二氢-2,7-二甲基-4-氧代-6-喹唑啉基)甲基] -N-丙-2-炔基氨基] -2-氟氨基苯甲酸酯-4-(1H-1,2,3,4-四唑-5-基)丁酸
