Various amidinophenol derivatives (27-47) and their benzoates (4-26) were synthesized and evaluated for inhibitory activities against trypsin, plasmin, kallikrein, thrombin, Clr and Cls as well as in vitro complement-mediated hemolysis. 4-(β-Amidinoethenyl) phenyl 4-guanidinobenzoate (15) and 4-amidino-2-benzoylphenyl 4-guanidinobenzoate (26) were found to have potent inhibitory activities with IC50s of 9×10-8M (trypsin) and 2×10-7M (Cls) for the former and 3×10-8M (trypsin) and 2×10-7M (Cls) for the latter.
多种amidinophenol衍生物(27-47)及其苯甲酸酯(4-26)被合成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的抑制活性,以及体外补体介导的溶血作用。4-(β-脒基乙烯基)苯基4-胍基苯甲酸酯(15)和4-脒基-2-苯甲酰苯基4-胍基苯甲酸酯(26)被发现具有强大的抑制活性,前者的IC50值为9×10-8M(胰蛋白酶)和2×10-7M(Cls),后者的IC50值为3×10-8M(胰蛋白酶)和2×10-7M(Cls)。
