By developing 6-amidino-2-naphthyl 4-guanidinobenzoate (I, FUT-175) as a basic structure, its various derivatives were synthesized and their inhibitory activities on trypsin, plasmin, kallikrein, thrombin, C1^- and C1s^- as well as on complement-mediated hemolysis were examined. The protective effect of these compounds on complement-mediated Forssman shock was also examined in guinea pigs. 6-Amidino-2-naphthyl 4-[(4, 5-dihydro-1H-imidazol-2-yl)amino]-benzoate (41, FUT-187) was found to be a suitable compound for oral administration with anti-complement activity superior to that of compound I.
通过开发6-氨基脲基-2-萘基4-胍基苯甲酸(I,FUT-175)作为基本结构,合成了其多种衍生物,并测试了它们对胰蛋白酶、纤溶酶、激肽释放酶、凝血酶、C1^-和C1s^-的抑制活性,以及对补体介导的溶血作用的影响。还对这些化合物在豚鼠中对补体介导的Forssman休克的保护作用进行了研究。研究发现,6-氨基脲基-2-萘基4-[(4, 5-二氢-1H-咪唑-2-基)氨基]-苯甲酸(41,FUT-187)是一种适合口服给药的化合物,其抗补体活性优于化合物I。
