against thrombin, trypsin, and pancreatic kallikrein. An outstanding inhibitor of trypsin was found in bis(5-amidino-2-benzimidazolyl)methane (compound 42) with a Ki value of 1.7 X 10(-8) M(pH. 8.1, 37 degrees C). Another derivative, 1,2-di(4-amidino-2-benzofuranyl)ethane (compound 21), proved to be a highly effective inhibitor of the overall blood clotting process. From a general structure-activity standpoint
评估了一系列62种二芳基idine胺衍生物的抗蛋白水解活性。在除两种化合物之外的所有化合物中,一个或两个被ino基取代的芳基部分是吲哚或吲哚样环。后者包括茚,苯并咪唑,苯并呋喃,苯并β-噻吩和一些其他相关的含氮杂环。几种化合物对凝血酶,胰蛋白酶和胰激肽释放酶具有相当大的抑制作用。在双(5-ami基-2-苯并咪唑基)甲烷(化合物42)中发现了一种出色的胰蛋白酶抑制剂,Ki值为1.7 X 10(-8)M(pH.8.1,37摄氏度)。另一种衍生物1,2-二(4-ami基-2-苯并呋喃基)乙烷(化合物21)被证明是整个血液凝固过程的高效抑制剂。
