Amidino compounds represented by the formula (I) ##STR1## and pharmaceutically acceptable acid addition salts thereof are novel compounds and are useful as powerful antitrypsine, antiplasmin, antikallikrein 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. ##STR2##
