生物活性

α-Methyl-p-tyrosine is a competitive inhibitor of tyrosine hydroxylase, which converts tyrosine into DOPA. α-Methyl-p-tyrosine is also an orally active inhibitor of catecholamine synthesis, inhibiting the hydroxylation of tyrosine into DOPA. α-Methyl-p-tyrosine can be used in research related to epilepsy, glaucoma, cancer, and other related diseases[1][2][3][4].

體外研究
(In Vitro)

α-Methyl-p-tyrosine (1 μM,2 天) 可在人類(lèi)葡萄膜黑色素細(xì)胞中有效抑制 Latanoprost (HY-B0577) 誘導(dǎo)的黑色素生成[3]
α-Methyl-p-tyrosine (2 g/天,持續(xù) 10 個(gè)月) 可有效抑制嗜鉻細(xì)胞瘤中兒茶酚胺的合成,發(fā)揮抗腫瘤活性[4]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

體內(nèi)研究
(In Vivo)

α-Methyl-p-tyrosine (250 mg/kg,腹腔注射,單次給藥) 可在雄性 CFI 小鼠體內(nèi)加劇 Pentylenetetrazol 誘導(dǎo)的強(qiáng)直和陣攣性癲癇發(fā)作的嚴(yán)重性和持續(xù)時(shí)間[2]。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
