5-Deazafolate and 5-deazatetrahydrofolate (DATHF) analogues with the glutamic acid side chain replaced by homocysteic acid (HCysA), 2-amino-4-phosphonobutanoic acid (APBA), and ornithine (Orn) were synthesized as part of a larger program directed toward inhibitors of folylpolyglutamate synthetase (FPGS) as probes of the FPGS active site and as potential therapeutic agents. The tetrahydro compounds
谷氨酸侧链被高半胱氨酸(HCysA),2-氨基-4-膦酰基丁酸(APBA)和鸟氨酸(Orn)取代的谷氨酸侧链的5-脱氮叶酸酯和5-脱氮叶酸酯(DATHF)类似物被合成为一个较大程序的一部分直接针对叶酰聚谷氨酸合成酶(FPGS)的抑制剂,作为FPGS活性位点的探针和潜在的治疗剂。四氢化合物作为嘌呤生物合成酶甘氨酰胺核糖核苷酸甲酰基转移酶(GARFT)的不可聚谷氨酸抑制剂也受到关注。N2-乙酰氨基-6-甲酰吡啶并[2,3-d]嘧啶-4(3H)-与4-氨基苯甲酸的还原偶联,然后进行N10-甲酰化,混合酸酐缩合生成的N2-乙酰基-N10-甲酰-5-脱氮杂戊酸与L-高半胱氨酸,并用NaOH去除N2-乙酰基和N10-甲酰基 得到N-(5-脱氮杂戊酰基)-L-同型半胱氨酸(5-dPteHCysA)。N2-乙酰基-N10-甲酰基5-去氮杂戊酸与甲基D,L-2-氨基-4-(二乙氧基膦基)丁酸的混合酸酐缩合,
