應用

Methotrexate Related Compound B USP reference standard for use in specified quality tests and assays.

Additionally used to prepare standard, standard stock, system suitability, and system suitability stock solutions for impurity analysis in the given below monographs according to United States Pharmacopeia (USP):

• Methotrexate
• Methotrexate Injection
• Methotrexate for Injection

生化／生理作用

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。

聯結

比甲氨喋呤更有效，但毒性也更强。
