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. ##STR2##
式为##STR1##的
氨基甲酸化合物及其药学上可接受的酸盐是新型化合物,可用作强效的抗胰
蛋白酶、抗纤溶酶、抗激肽酶和抗凝血酶剂。它们具有强大的抗Cl(Clr、Cls)活性和抗补体活性,因此也可用作抗补体剂。这些
氨基甲酸化合物是通过将式为(II)R.sub.1-COOH(II)的
羧酸化合物与
氨基苯酚化合物(III)进行常规酯化反应制备的,必要时可转化为其药学上可接受的酸盐。##STR2##
