SULPHONAMIDE DERIVATIVES

The invention relates to sulphonamide derivatives of formula (I), where RC is selected from a group consisting of dialkylamino, NO2, CN, aminocarbonyl, monoalkylaminocarbonyl, dialkylaminocarbonyl, alkanoyl, oxazol-2-yl, oxazolylaminocarbonyl, aryl, aroyl, aryl-CH(OH)-, arylaminocarbonyl, furanyl, where the aryl, aroyl and furanyl moieties may be substituted, guanidinyl-(CH2)z-N(R')-, Het-(CH2)z-N(R')-, Het-CO-N(R')-, Het-CH(OH)- and Het-CO-, where Het is an optionally substituted 4-6-membered heterocyclic ring containing one or more heteroatoms sleeted from N, S and O, R' is hydrogen or alkyl, and z is an integer 1 to 5; RA is a group of formula (A), (B), (C) or (D) as defined in the claims; and RB is hydrogen, alkyl, alkanoyl, hydroxyalkyl, alkoxyalkyl, alkoxycarbonyl, alkoxycarbonylalkyl, aminoalkyl, mono- or dialkylaminoalkyl or Het-alkyl, where Het is as defined above. The invention also relates to the use of derivatives of formula (I) as inhibitors for collagen receptor integrins and a process for preparing sulphonamides of formula (II).
