FIELD: chemistry.SUBSTANCE: present invention relates to a piperidine derivative of general formula (I),where Rdenotes hydrogen or a substitute selected from the following (b)-(i): b) acrylic acid (including alkyl ester and hydroxyalkyl amide), (c) ureide, (d) alkenyl, (e) aminoalkyl which can be substituted with alkyl carbonyl or aminocarbonyl, (f) carbonyl alkyl, substituted with hydroxy, alkoxy or hydroxyalkylamino, (g) carbonyl, substituted with hydroxy, morpholino, alkoxy, hydroxyalkyl aminoalkoxy or cyclohexyloxy carbonyloxyalkoxy, (h) carbonylamino, substituted with alkyl or alkoxy, (i) aminocarbonyl which can be substituted with one or two substitutes selected from amino, hydroxy, alkoxy, alkenyl and alkyl (which can be substituted with halogen, thiol, piperidino, amino, alkoxy, alkoxycarbonyl, aminocarbonyl or one or two hydroxy); Rdenotes hydrogen or a substitute selected from the following (j)-(r): (j) cyano, (k) acrylic acid, (l) alkyl, substituted with hydroxy or piperidino, (m) carbonyl alkyl, substituted with hydroxy, alkoxy (which can be substituted with cyclohexyloxy carbonyloxy) or hydroxyalkylamino, (n) carbonyl, substituted with hydroxy or alkoxy, (o) carbonyl alkoxy, substituted with alkoxy, (p) carbonyl alkyl sulphanyl, substituted with hydroxy or alkoxy, (q) alkoxy, (r) halogen; and Rdenotes hydrogen or a substitute selected from the following (s)-(w): (s) alkyl which can be substituted with carboxy, cyano, pyrrolidyl, piperidino, alkoxy, alkyl sulphanyl or one or two hydroxy, (t) carbonyl, substituted with alkyl or alkoxy, (u) carbonyl alkoxyalkyl, substituted with hydroxy or alkoxy, (v) carbonyl alkyl, substituted with alkyl, alkoxy or alkylphenyl, (w) aminoalkyl, substituted with aminocarbonyl or alkane sulphonyl, where one of said Rand Rdenotes a substitute other than hydrogen, A is unsubstituted or is an oxo, B denotes carbon or oxygen, one of X and Y denotes carbon and the other denotes sulphur, the dotted line denotes a single bond or a double bond, under the condition that when Rdenotes halogen or alkoxy, A is unsubstituted, Rdenotes a substitute other than hydrogen and B denotes oxygen. The invention also relates to an antihistamine which contains a compound of formula I and use of the described compound for treatment and production of a medicinal agent.EFFECT: novel compounds having antagonistic action on histamine receptors are obtained and described and can be suitable as active ingredients of a pharmaceutical composition, especially an antihistamine composition.17 cl, 40 ex, 21 tbl |
