This invention relates to derivatives having the formula: ##STR1## in which R.sub.1 is hydrogen or alkyl having 1-6 carbon atoms; X is (CHR.sub.2).sub.m in which m is an integer from 2 to 15, or (CHR.sub.2).sub.n R.sub.3 in which n is an integer from 1 to 15, R.sub.2 is hydrogen, or a hydroxy, acyloxy or alkyl group having 1-6 carbon atoms, and the various symbols R.sub.2 may have different meanings in each radical (CHR.sub.2) when several radicals (CHR.sub.2) are present, R.sub.3 is a trichloromethyl, acetyl, carboxy or alkoxycarbonyl group, or a phenyl, phenoxy, benzoyl, thienyl or pyridyl radical optionally substituted with at least a halogen atom, or a hydroxy, nitro, amino, cyano, carboxy, alkyloxycarbonyl, alkyl having 1-6 carbon atoms, alkoxy having 1-6 carbon atoms or methylenedioxy group, and to the acid addition salts of the derivatives of the formula (I). Said derivatives have useful anti-inflammatory and anti-arrhythmic activities and an inhibiting action on blood platelet aggregation.
这项发明涉及具有以下结构的衍生物:##STR1## 其中R.sub.1是氢或具有1-6个碳原子的烷基;X是(CHR.sub.2).sub.m,其中m是2到15之间的整数,或(CHR.sub.2).sub.n R.sub.3,其中n是1到15之间的整数,R.sub.2是氢,或者是具有1-6个碳原子的羟基,酰氧基或烷基基团,各种符号R.sub.2在每个基团(CHR.sub.2)中可能有不同的含义,当存在多个基团(CHR.sub.2)时,R.sub.3是三氯甲基,乙酰基,羧基或烷氧羰基基团,或苯基,苯氧基,苯甲酰基,噻吩基或吡啶基,可选择地取代至少一个卤原子,或羟基,硝基,氨基,氰基,羧基,烷氧羰基,具有1-6个碳原子的烷基,具有1-6个碳原子的烷氧基或亚甲二氧基基团,以及公式(I)的衍生物的酸盐。这些衍生物具有有用的抗炎和抗心律失常活性,以及对血小板聚集的抑制作用。
