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; R
A
is a group of formula (A), (B), (C) or (D) as defined in the claims; and R
B
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).
