FIELD: chemistry; pharmaceutics.
SUBSTANCE: invention relates to novel sulfonamide derivatives of general formula (1) or pharmaceutically acceptable salts thereof, possessing the properties of inhibition integrin α4β7. In general formula (1) (1), A means a group presented by general formula (2-1) or (2-2)
, where Arm is a 5- or 6-member aromatic ring, containing 0, 1 or 2 heteroatoms, selected from nitrogen atoms, R1 and R11, each, independently, represents any substitute selected from a hydrogen atom, halogen atom, lower alkyl group, lower alkoxy group, mono- or di-lower alkylamino group, R12, R13 and R14, each, independently, represents any substitute selected from a hydrogen atom, lower alkyl group, lower alkoxy group, amino group, lower alkylamino group, low di(alkyl)amino group or (lower alkylamino)lower alkyl group, R2 and R3, each, independently, represents any substitute selected from a hydrogen atom, lower alkyl group or lower alkoxy group, B is represents any substitute selected from lower alkoxy group, optionally substituted by hydroxyl group, lower alkyl group, mono- or di-lower alkylamino group; C3-C6cyclic alkoxy group and/or 6-member(s) heterocyclic(s) group (groups) with an oxygen atom, sulphur atom or a nitrogen atom as heteroatom, hydroxyl group, R41 is represents a hydrogen atom or lower alkyl group, a, b, c and d, each, independently, represents C-R31, C-R32, C-R33 and C-R34 respectively, but one or two of a, b, c and d, each, can be a nitrogen atom, R31, R32, R33 and R34, each, independently, represents any substitute selected from a hydrogen atom, halogen atom, lower alkyl group, lower alkoxy group, provided that any R31, R32, R33 and R34 represents a halogen atom or lower alkyl group, e, f, g and h, each, independently, represents C-R35, C-R36, C-R37 and C-R38 respectively, however, one or two of e, f, g and h, each, can be a nitrogen atom, R35, R36, R37 and R38, each, independently, represents any substitute selected from a hydrogen atom, lower alkyl group or lower alkoxy group, D represents a phenyl group or a 5 -or 6-member aromatic heterocyclic group, containing a nitrogen atom, an oxygen atom or sulphur atom, optionally containing a substitute(s), selected from a group consisting of hydroxyl groups, lower alkyl groups, lower alkoxy groups, E is a 5- or 6-member heterocyclic group with 1-4 heteroatoms, selected from nitrogen atoms, an oxygen atom and sulphur atom in the cycle, optionally containing a substitute(s), selected from a group consisting of halogen atoms, hydroxyl groups, lower alkyl groups, lower alkoxy groups, amino groups, 4- or 6-member cyclic amino groups, carboxyl groups and lower alkoxy-carbonyl groups; aminocarbonyl group, optionally containing a substitute(s) selected from the group, consisting of hydroxyl groups, lower alkyl groups, lower alkoxy groups, 5- or 6-member heterocyclic groups, containing 1, 2, 3 or 4 heteroatoms, selected from a group consisting of oxygen atoms, sulphur atoms and nitrogen atoms as a component(s) ring atom(s), and substituted by heterocycle of lower alkyl groups, where heterocycle means a 5- or 6-member heterocyclic groups, containing 1, 2, 3 or 4 heteroatoms, selected from group consisting of oxygen atoms, sulphur atoms and nitrogen atoms as a component(s) ring atom(s); hydrogen atom, hydroxyl group, lower alkyl group, lower alkoxy group, amino group, lower alkyl-carbonyl group, lower alkyloxy-carbonyl group or a lower alkylaminoalkilen group, and provided that the lowest alkyl-carbonyl group and the lowest alkyloxycarbonil group can be, each of which, are connected to a phenyl group, presented D, to form condensed ring.
EFFECT: compounds can be used for treating or preventing an inflammatory disease, in which the pathological condition associated with indirect by integrins α4β7 adhesion process.
