The preliminarily published synthesis(4) of decapeptides with the amino acid sequence of Val5-hypertensin I has been repeated several times. The products showed a high hypertensive activity, comparable with that of the corresponding octapeptides [Val5-hypertensin II and Val5-hypertensin II-Asp-β-amide(12)]. The synthesis yielding the purest intermediates and products is described in this paper. The
先前公开的具有Val 5-高血压蛋白I氨基酸序列的十肽合成(4)已重复了几次。产物显示出高血压活性,与相应的八肽[Val 5-高血压蛋白II和Val 5-高血压蛋白II-Asp-β-酰胺(12)]相当。本文描述了产生最纯净的中间体和产物的合成方法。合成的Val 5-高血压蛋白I和Val 5的化学纯度很高通过逆流分布,纸色谱,元素分析和水解后的氨基酸测定来确定β-高血压蛋白I-Asp-β-酰胺。游离的结晶肽H•Val-Tyr•OH(L-L),H•Val-His•OH(L-L),H•Val-Tyr-Val•OH(L 3),H•Val-Tyr -Val-His ·OH(L 4)和H·Pro-Phe·OH(L-L)由合成中间体制备。
