Abstract
Compound of the formula ##STR1## in which R and R' represent hydrogen or an optionally substituted hydrocarbon radical or acyl radical, R.sub.1 represents hydrogen or an optionally substituted hydrocarbon radical of aliphatic or aromatic character, R.sub.2 represents hydrogen or an optionally substituted hydrocarbon radical of higher aliphatic or aromatic character, it being possible for R.sub.1 and R.sub.2 together to represent also an optionally substituted alkylene radical or an optionally substituted biphenyl-2,2'-ylene radical, whereby however, when R, R.sub.1 and R.sub.2 are hydrogen, R' cannot be methyl and salts of such compounds that contain a salt-forming grouping, and pharmaceutical compositions containing these compounds. The pharmaceutical compositions containing these compounds are particularly valuable for treating liver and veneous diseases.
