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。
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。
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。还可有效治疗耐甲氧嘧啶的 间日 疟原虫。

生化/生理作用

甲氨蝶呤是一种二氢叶酸还原酶(DHFR)的变构抑制剂,DHFR是一种催化二氢叶酸转化为四氢叶酸的酶。 由于嘌呤和嘧啶的合成需要四氢叶酸,甲氨蝶呤处理会抑制DNA和RNA的合成。
