Compound of the formula
in which
R and R' represent hydrogen or an optionally substituted hydrocarbon radical or acyl radical,
R1 represents hydrogen or an optionally substituted hydrocarbon radical of aliphatic or aromatic character,
R2 represents hydrogen or an optionally substituted hydrocarbon radical of higher aliphatic or aromatic character, it being possible for
R1 and R2 together to represent also an optionally substituted alkylene radikal or an optionally substituted biphenyl-2,2'-ylene radical,
whereby however, when R, R and R2 are hydrogen, R' cannot be methyl and salts of such compounds that contain a saltform- ing grouping, and pharmaceutical compositions containing these compounds.
The pharmaceutical compositions containing these compounds are particularly valuable for treating liver and venous diseases.
式中的化合物
其中
R 和 R'代表氢或任选取代的烃基或酰基、
R1 代表氢或任选取代的脂肪族或芳香族烃基
R2 代表氢或任选取代的高脂族或芳香族烃基,可以是
R1 和 R2 还可以代表任选取代的亚烷基或任选取代的联苯-2,2'-亚烯基、
然而,当 R、R 和 R2 均为氢时,R'不能为甲基和含有盐基的此类化合物的盐,以及含有这些化合物的药物组合物。
含有这些化合物的药物组合物对治疗肝脏和静脉疾病特别有价值。
