产品描述

PGlu-3-methyl-His-Pro-NH2 TFA (A-42872 TFA), the modified thyrotropin-releasing hormone (TRH) peptide, enhances binding to pituitary TRH receptors and increases stimulation of thyroid-stimulating hormone (TSH) release from the pituitary. The in vitro permeability of PGlu-3-methyl-His-Pro-NH2 TFA through rat skin is increased in the presence of enhancers Ethanol and Cineole[1][2].

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[1].

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[1].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)[2].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[2]. Animal Model: Male Sprague-Dawley rats (weighing 296-356 g)[2]
