Product Description
Application
氨基蝶呤已被用于生产抗神经颗粒蛋白抗体。
Biochem/physiol Actions
研究发现氨基蝶呤在小鼠模型中抑制生长、胚胎形成并具有毒性作用。它起堕胎药的作用。现已确知氨基蝶呤可减轻儿童急性白血病的影响。
与二氢叶酸还原酶结合并抑制其活性的叶酸拮抗剂。
叶酸拮抗剂。氨基蝶呤是由叶酸转运蛋白运输至细胞内的。在细胞内，它被叶酰聚谷氨酸合酶转化为一种高分子量的聚谷氨酸盐代谢物，该产物又与二氢叶酸还原酶结合并抑制其活性。氨基蝶呤-聚谷氨酸盐经 γ-谷氨酰基水解酶作用发生细胞内降解。
Other Notes
比甲氨喋呤更有效，但毒性也更强。
