3-d]pyrimidin-5-yl)ethyl]benzoyl]-l-glutamic acid (2) and N-[2-amino-4-ethyl-6-methyl[(pyrrolo[2,3-d]pyrimidin-5-yl)ethyl]benzoyl]-l-glutam ic acid (4), were designed and synthesized as potent dual inhibitors of thymidylate synthase (TS) and dihydrofolate reductase (DHFR) and as antitumor agents. Compound 2 had inhibitory potency against human DHFR similar to N-[4-[2-(amino-3,4-dihydro-4-oxo-7H-pyrrolo[2,
两种新颖的类似物,N- [2-氨基-4-乙基[(吡咯并[2,3-d]嘧啶-5-基)乙基]苯甲酰基] -1-谷氨酸(2)和N- [2-氨基-设计并合成了4-乙基-6-甲基[(吡咯并[2,3-d]嘧啶-5-基)乙基]苯甲酰基] -1-谷氨酸(4),作为有效的胸苷酸合酶双重抑制剂(TS )和二氢叶酸还原酶(DHFR)并用作抗肿瘤药。化合物2具有类似于N- [4- [2-(氨基-3,4-二氢-4-氧代-7H-吡咯并[2,3-d]嘧啶-5-基)乙基]苯甲酰基的对人DHFR的抑制能力。 ] -L-谷氨酸(LY231514)和1,而4对人DHFR没有活性。2和4都比LY231514更能抵抗大肠杆菌。抗人TS的功效比LY231514低7倍,而4表现出与LY231514相似的抑制活性。与2相比,它是人类草氨酸谷氨酸合成酶(FPGS)的有效底物,4是FPGS的不良底物。在标准的NCI临床前体外筛选中,化合物2
