The synthesis and design using molecular modeling techniques for non-peptide, low molecular weight novel fibrinogen receptor (glycoprotein IIb/IIIa: Gp IIb/IIIa) antagonists, is reported. We used a highly potent serine protease inhibitor, Nafamostat, having an amidinonaphthyl unit as the starting compound. The compounds 4-(6-amidino-2-naphthylaminocarbonyl)phenoxyacetic acid (5a) and 4-(6-amidino-
报道了使用分子建模技术针对非肽,低分子量新型纤维蛋白原受体(糖蛋白IIb / IIIa:Gp IIb / IIIa)拮抗剂的合成和设计。我们使用了一种高效的丝氨酸蛋白酶抑制剂,Nafamostat,其具有ona基萘基单元作为起始化合物。化合物4-(6-ami基-2-萘氨基羰基)苯氧基乙酸(5a)和4-(6-ami基-2-萘甲酰胺基)苯氧基乙酸(5b)抑制5'-二磷酸腺苷(ADP)诱导的人聚集。富含血小板的血浆(PRP)的IC50值分别为0.05和0.07 microM,并且失去了抑制多种丝氨酸蛋白酶(包括凝血酶,Xa因子,纤溶酶和胰蛋白酶)的能力。
