A series of pseudopeptide analogues of the C-terminal hexapeptide of neurotensin (NT8-13), namely [Tyr11 psi[COCH2]Phe12]-, [Ile12 psi[COCH2]Phe13]-, and [Tyr11 psi[CH(CN)NH]Ile12]NT8-13 with different stereochemistries, has been synthesized and evaluated for its potency in displacing labeled NT from rat cortex membranes. Ketomethylene pseudohexapeptides were prepared from the corresponding Boc-protected
神经降压素(NT8-13)C端六肽的一系列假肽类似物,即[Tyr11 psi [COCH2] Phe12]-,[Ile12 psi [COCH2] Phe13]-和[Tyr11 psi [CH(CN)NH]合成了具有不同立体化学的] Ile12] NT8-13,并评估了其从大鼠皮质膜置换标记的NT的功效。酮亚甲基假六肽由相应的Boc保护的酮亚甲基二肽衍生物使用不同的固相合成(SPS)条件制备,而(氰基亚甲基)氨基类似物则采用Fmoc策略通过SPS直接制备。H-Arg-Arg-Pro-Tyr psi [COCH2] -Phe-Leu-OH与受体结合的能力几乎与NT8-13和[Phe12] NT8-13相同。假六肽亲和力的比较,此处报道,
