aminopterin analogues were evaluated for antiarthritic activity in the mouse type II collagen model. New compounds in the 5-deaza series were prepared by alkylation of an appropriate N-substituted (4-aminobenzoyl)-L-glutamic acid dialkyl ester or N-(5-amino-2-thenoyl)-L-glutamate diester with a 2,4-diamino-5-alkyl-6-(bromomethyl)-5-deazapteridine. The resultant 5-deazaaminopterin diesters were saponified
在小鼠II型胶原蛋白模型中评估了衍生自5-deaza-和5,10-dideazaaminopterin系列的氨基蝶呤类似物的26种化合物的抗关节炎活性。通过将合适的N-取代的(4-氨基苯甲酰基)-L-谷氨酸二烷基酯或N-(5-氨基-2-thenoyl)-L-谷氨酸二酯烷基化来制备5-deaza系列的新化合物,4-二氨基-5-烷基-6-(溴甲基)-5-脱氮庚啶。将所得的5-脱氮杂min蝶呤二酯皂化以提供目标5-脱氮杂合物类似物。通过适当的4-羧基苯基乙酸,(5-羧基-2-噻吩基)乙酸或(5-羧基-2-吡啶基)乙酸二甲基酯的碳负离子的类似烷基化反应合成5,10-二氮杂氨基蝶呤。2,4-二氨基-4-脱氧-10-羧基-5的二酯 将如此获得的10-二氮杂叠氮酸类型皂化,然后通过在Me 2 SO溶液中加热而容易地脱羧,以提供2,4-二氨基-5,10-二氮杂叠氮酸类型的中间体。肽与L-谷氨酸二乙酯偶
