简要描述:
PGlu-3-methyl-His-Pro-NH2 TFA (A-42872 TFA) 是一种修饰的促甲状腺激素释放激素 (TRH) 肽,能增强与垂体促甲状腺素释放激素受体的结合,增加垂体促甲状腺素 (TSH) 释放的刺激。PGlu-3-methyl-His-Pro-NH2 TFA 在增强剂乙醇和桉叶碱下,通过大鼠皮肤的体外通透性增加。

In Vitro: PGlu-3-methyl-His-Pro-NH2 TFA (A-42872 TFA) has a very high affinity for the TRH receptor in the CNS. PGlu-3-methyl-His-Pro-NH2 TFA is more potent in eliciting behavioral effects as well as being more potent in the release of both growth hormone and thyroid stimulating hormone.
In Vivo: PGlu-3-methyl-His-Pro-NH2 TFA (A-42872 TFA) (300 μg/kg; i.v.) elicits a 80 % increase in cerebral blood flow. Even a minute dose of PGlu-3-methyl-His-Pro-NH2 TFA (625 ng kg-1) causes an increase in cerebral blood flow.
The addition of 3% terpene in combination with 47% ethanol increases the penetration of PGlu-3-methyl-His-Pro-NH2 TFA (5 mg/ml; transdermal administration; 30 minutes).
Topical application of PGlu-3-methyl-His-Pro-NH2 TFA induces an increase in TSH serum concentration from 0.32 ng/ml to 22.9 ng/ml, respectively, after 30 min. The addition of Terpene and Ethanol in combination with TRH or PGlu-3-methyl-His-Pro-NH2 TFA, increases the TSH release to 43 and 48.4 ng/ml, respectively.
