A quinone compound of the formula: ##STR1## wherein R stands for an alkyl group of 1 to 22 carbon atoms having at its terminal end a hydroxyl group which may be protected, can be obtained with industrial advantage by allowing a compound of the formula: ##STR2## to react with a peroxide of a carboxylic acid of the formula: RCOOH wherein R is as defined above, or with a peroxide of an acid anhydride of the carboxylic acid. The quinone compound wherein R stands for an alkyl group of 1 to 2 carbon atoms having at its terminal end an optionally protected hydroxyl group, is a novel compound and has antifibrotic activity.
该公式的醌化合物为:其中R代表1至22个碳原子的烷基基团,在其末端具有一个可能被保护的羟基,可以通过让该公式的化合物与具有以下公式的羧酸过氧化物:进行反应来获得工业优势,其中R如上定义,或与羧酸的酸酐的过氧化物反应。其中R代表1至2个碳原子的烷基基团,在其末端具有一个可选择保护的羟基的醌化合物是一种新颖的化合物,具有抗纤维化活性。
