Rotationally restricted analogues of 5-deazapteroyl-L-glutamate and (6R,6S)-5-deaza-5,6,7,8-tetrahydropteroyl-L-glutamate with a one-carbon bridge between the amide nitrogen and the 6'-position of the p-aminobenzoyl moiety were synthesized and tested as substrates for folylpolyglutamate synthetase (FPGS), a key enzyme in folate metabolism and an important determinant of the therapeutic potency and
5-脱氮杂戊酰基-L-谷氨酸和(6R,6S)-5-deaza-5,6,7,8-四氢蝶酰基-L-谷氨酸的旋转受限类似物,在酰胺氮和6'-之间具有一碳桥合成了对氨基苯甲酰基部分的位置并作为叶酸聚谷氨酸合成酶(FPGS)的底物进行了测试,叶酸是谷氨酸代谢中的关键酶,是经典抗叶酸药物治疗效果和选择性的重要决定因素。还合成了相应的5-脱氮杂戊酰基-L-鸟氨酸和(6R,6S)-5-deaza-5,6,7,8-四氢蝶酰基-L-鸟氨酸的桥接类似物作为潜在的抑制剂。L-谷氨酸二乙酯与2-溴甲基-4-硝基苯甲酸甲酯缩合,然后催化还原硝基,与2-乙酰氨基-6-甲酰基吡啶基还原偶合[2,3-d]嘧啶-4(3H)-在二甲基氨基硼烷存在下,用HBr / AcOH酸解生成2-L- [5- [N-(2-乙酰氨基-4(3H)-氧吡咯并] [2,3 -d]嘧啶-6-基)甲氨基] -2,3-二氢-1-氧代-2(1H)-异吲哚基
