Various amidinonaphthols and their acyl derivatives were synthesized and evaluated for inhibitory activities against trypsin, plasmin, kallikrein, thrombin, Clr and Cls, as well as against in vitro complement-mediated hemolysis. 6-Amidino-2-naphthyl 4-guanidinobenzoate (74, FUT-175) was found to have potent inhibitory activities, particularly against trypsin (IC50 : 0.02 μM), Clr (IC50 : 0.1 μM) and Cls (IC50 : 0.02 μM), and to be highly effective in inhibiting the complement-mediated hemolysis (IC50 : 0.03μM). FUT-175, furthermore, showed considerable effectiveness in the systemic Forssman shock reaction, in which involvement of the complement system as the pathogenetic factor is well established.
合成了多种 amidinonaphthol 及其酰基衍生物,并评估了它们对胰蛋白酶、纤溶酶、激肽释放酶、凝血酶、Clr 和 Cls 以及体外补体介导溶血的抑制活性。发现 6-Amidino-2-萘基 4-胍基苯甲酸酯(74,FUT-175)具有强大的抑制活性,尤其对胰蛋白酶(IC50:0.02 μM)、Clr(IC50:0.1 μM)和 Cls(IC50:0.02 μM),并且在抑制补体介导溶血方面非常有效(IC50:0.03 μM)。此外,FUT-175 在全身性福斯曼休克反应中显示出显著的疗效,该反应中补体系统作为致病因素的作用已被充分证实。
