N-Terminal tetrapeptide analogs of fibrin α-chain were synthesized by the solution method using a new active ester, the ester of the oxime of p-nitroacetophenone, and by the solid-phase method. Their inhibitory effects on fibrinogen/thrombin clotting were examined. Of the synthetic peptides, amide analogs of Gly-Pro-Arg-Pro exhibited a more potent inhibitory effect.
采用溶液法和固相法合成了纤维蛋白α链的N端四肽类似物,使用了一种新的活性酯,即对硝基乙酰苯酮的腙酯。考察了它们对纤维蛋白原/凝血酶凝固的抑制作用。在合成的肽中,甘氨酸-脯氨酸-精氨酸-脯氨酸的酰胺类似物表现出更强的抑制效果。
