Synthesis of thyrotropin-releasing hormone-related peptides using N.ALPHA.-tert-dutyflxycarbonyl-.OMEGA.-(N-tert-butyloxycarbonylcarbamoyl)-.ALPHA.-amino acids.
摘要:
研究人员研究了 Nα,Nca-二叔丁氧羰基高谷氨酰胺在合成促甲状腺激素释放激素(TRH)类似物中的应用。在含有乙酸的水或二氧六环中,均谷氨酰胺肽形成δ-内酰胺比谷氨酰胺肽形成γ-内酰胺更容易。[pHgu1,Nva2]-TRH 对小鼠戊巴比妥麻醉具有剂量依赖性拮抗活性,但对大鼠脑中的 TRH 受体几乎没有结合活性。

Thyrotropin-releasinghormone (TRH) analogues which show relative selectivity for action in the central nervous system have been recognized. Practical syntheses for three of these TRH analogues which show the greatest selectivity, less than Aad-His-Tzl-NH2 (5), less than Glu-His-Pip-OMe (2), and less than Aad-His-Pro-NH2 (6), are described. The first two were prepared by solution methods of peptide

Application of Nα, Nca-di-tert-butyloxycarbonylhomoglutamine to synthesis of thyrotropin-releasing hormone (TRH) analogs was examined. The δ-lactam formation from homoglutaminylpeptides took place more easily than γ-lactam formation from glutaminylpeptides in water or dioxane containing acetic acid. [pHgu1, Nva2]-TRH had dose-dependent antagonistic activity against pentobarbital anesthesia in mice, but almost no binding activity to TRH receptor in rat brain.
