The present invention relates to sulphonamide derivatives, whith a urea moiety. The invention also relates to the use of the derivatives as inhibitors of collagen receptor integrins, especially α2β1 integrin inhibitors e.g. in connection with diseases and medical conditions that involve the action of cells and platelets expressing collagen receptors, their use as a medicament, e.g. for the treatment of thrombosis, inflammation, cancer and vascular diseases, pharmaceutical compositions containing them and a process for preparing them. The sulphonamide derivatives have the general formula (I) or (I').
A compound represented by the formula (I): wherein R
1
is lower alkyl, cycloalkyl or aromatic hydrocarbon ring, each of which is optionally substituted with one or more substituents; R
2
is hydrogen atom, halogen atom, lower alkyl, halo(lower)alkyl or lower alkoxy; and R
3
is (1) a group represented by the formula: wherein R
4
is lower alkyl, etc.; (2) a group represented by the formula: wherein R
5
is lower alkyl, etc.; (3) a group represented by the formula: wherein R
6
is lower alkyl, etc.; or (4) a group selected from halogen atom, carboxy, hydroxy and lower alkoxy, or a salt thereof.
