Patent number: 4570006Abstract: Amidino compounds represented by the formula ##STR1## and pharmaceutically acceptable acid addition salts thereof are novel compounds and are useful as powerful anti-trypsine, anti-plasmin, anti-kallikrein and anti-thrombin agents. Having strong anti-Cl (Clr, Cls) activities and an anticomplement activity, they are also useful as anticomplement agents. These amidino compounds are prepared by usual esterification of carboxylic acid compounds represented by the formula (II)R.sub.1 --COOH (II)with amidinophenol compound (III) and, if necessary, can be transformed into pharmaceutically acceptable acid addition salts thereof.Type: GrantFiled: October 24, 1984Date of Patent: February 11, 1986Assignee: Torii & Co. Ltd.Inventors: Setsuro Fujii, Takashi Yaegashi, Toyoo Nakayama, Yojiro Sakurai, Shigeki Nunomura, Toshiyuki Okutome
