Abstract: Sulphonamide derivatives of benzylamine of formula (I), wherein A represents phenyl unsubstituted or substituted; or 9- or 10-membered bicyclic group, linked to —(O)x—(CH2)y— through one of its aromatic carbon atoms, consisting of benzene ring fused with -membered heteroaromatic ring containing 1 or 2 heteroatoms independently selected from the group consisting of N and O, wherein such bicyclic group is unsubstituted or substituted or with 5- or 6-membered non-aromatic heterocyclic ring having 1 or 2 O atoms, wherein heterocyclic ring is unsubstituted or substituted with one or more C1-C3-alkyls; D represents a group selected from: phenyl unsubstituted or substituted; naphthyl unsubstituted or substituted; thiophene unsubstituted or substituted; bicyclic group consisting of imidazolering fused with 5-membered non-aromatic carbocyclic ring; bicyclic group consisting of benzene ring fused with 5-membered heteroaromatic ring, having 1 or 2 heteroatoms independently selected from the group consisting of N, O and
