ABSTRACT:
Sulfonates of hydroxycoumarins of the formula I ##STR1## where R.sup.1 and R.sup.2 are identical or different and are each hydrogen, halogen or alkyl of 1 to 5 carbon atoms which can be substituted by --NR.sup.4 R.sup.5, --OR.sup.4 or --OC(O)R.sup.4, where R.sup.4 and R.sup.5 are identical or different and are each hydrogen or alkyl of 1 to 4 carbon atoms, or R.sup.1 and R.sup.2 are each a carboxylic acid group --OC(O)R.sup.4 or a carboxamido radical, with the proviso that R.sup.1 is not methyl when R.sup.2 is hydrogen, or R.sup.1 and R.sup.2 together form a --(CH.sub.2).sub.n -- chain where n is 3-5, and R.sup.3 is a straight-chain or branched alkyl radical of 1 to 8 carbon atoms or cycloalkyl of 3 to 8 carbon atoms, each of which can be substituted by halogen, --OR.sup.4, --NR.sup.4 R.sup.5, --CN or phenyl, or R.sup.3 is a straight-chain or branched alkenyl radical of 3 to 8 carbon atoms, an amino group -- NR.sup.4 R.sup.5, or phenyl or naphthyl, each of which is unsubstituted or monosubstituted or polysubstituted by --OR.sup.4, --NR.sup.4 R.sup.5, --NO.sub.2, halogen, --SR.sup.4, --S(O)R.sup.4, --OS(O)R.sup.4, --SCF.sub.3, --OS(O)CF.sub.3, --CN, --C(O)R.sup.4, --OC(O)R.sup.4, --NHC(O)R.sup.4, --CF.sub.3, C.sub.1 -C.sub.4 -alkyl or a combination of these substituents, a process for their preparation, drugs containing these compounds, and compounds of the formula I, in which R.sup.1 is methyl and R.sup.2 is hydrogen, for use as drugs.
