1504505 Sulphonamides HOECHST AG 25 April 1975 [25 April 1974 27 Dec 1974] 17337/75 Heading C2C The invention comprises novel compounds (I) (including salts thereof) in which R1 and R2, which may be identical or different, each represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms, and, if R1 represents a hydrogen atom, R2 may also represent an alkoxymethyl group having from 1 to 4 carbon atoms in the alkoxy radical, a phenoxymethyl group or a phenylthiomethyl group, R3 represents a hydrogen atom, a straight or branched chain alkyl group having from 1 to 4 carbon atoms, a cycloalkyl group, having 5 or 6 ring members, one of which may be replaced by an oxygen or sulphur atom, a phenyl or benzyl group which may be substituted in the phenyl nucleus by one or more substituents selected from nitro groups, alkyl groups having from 1 to 3 carbon atoms, alkoxy groups having from 1 to 5 carbon atoms and halogen atoms, or represents a benzhydryl group or an alkanoyloxymethyl group having 2 to 4 carbon atoms in the alkanoyl part, X represents a halogen atom, a CF 3 or CCl 3 group, a straight or branched chain, saturated or unsaturated alkyl group having from 1 to 6 carbon atoms, a benzyl group which may be substituted in the phenyl nucleus by one or more substituents selected from halogen atoms, hydroxy and amino groups, and alkyl and alkoxy groups, or represents one of the groups -O-R4, -S-R4, SO-R4, SO 2 -R4 and NR4R5, in which R4 represents a phenyl group which may be substituted by one or more substituents selected from halogen atoms, CF 3 , OH and amino groups, alkyl and alkoxy groups having from 1 to 4 carbon atoms, and SO 2 NH 2 groups, or represents a straight or branched chain alkyl group having from 1 to 4 carbon atoms which may be substituted by a phenyl, pyridyl, furyl or thienyl group, and R5 represents a hydrogen atom, a straight or branched chain alkyl group having from 1 to 4 carbon atoms, and the group NR4R5 may represent a saturated, heterocyclic, 5- or 6-membered ring which may be interrupted by an O-, N- or S- atom, A represents a single bond, or an alkylene chain of 1 to 3 carbon atoms which may be unsaturated, interrupted by O-, N- or S-atoms or substituted by halogen atoms and/or substituted by alkyl, aralkyl, aryl groups or by mono-nuclear hetero-aromatic rings, or A represents an ortho-phenylene radical or the grouping in which Y represents a single bond or an alkylene group having from 1 to 4 carbon atoms, and R6 and R7, which may be identical or different, each represents a hydrogen or halogen atom or an alkyl group having from 1 to 4 carbon atoms. They are made by standard methods. Pharmaceutical preparations having diuretic and saluretic action contain (I) as active ingredient. Administration is enterally or parenterally. |
