General description

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Biochem/physiol Actions

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。

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Other Notes

比甲氨喋呤更有效,但毒性也更强。
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
