一般說明

Methotrexateis an analog of folate. It shows anti-inflammatory effects throughseveral cellular mechanisms. The inhibition of dihydrofolate reductase reducesthe de novo synthesis of pyrimidines and purines, transmetylation ofphospholipids and proteins, and formation of polyamines.

應用

二氢叶酸还原酶的有效抑制剂 和抗肿瘤的研究试剂。 用于抑制二氢叶酸还原酶在DHFR蛋白表达系统中的表达。也显示免疫抑制作用,如类风湿关节炎。
