PIPERIZINYLPYRIDINE DERIVATIVES AS ANTI-OBESITY AGENTS

FIELD: chemistry. ^ SUBSTANCE: invention relates to compounds of formula (I) , where R is hydrogen or (lower)alkyl; R1 is a (lower)alkyl or (C3-C7)cycloalkyl; X is nitrogen while Y is carbon or Y is nitrogen while X is carbon; m equals 0 or 1; Z is C(O) or SO2; R2 is selected from a group consisting of (lower)alkyl, (C3-C7)cycloalkyl or (C3-C7)cycloalkyl substituted with (lower)alkyl, (lower)phenylalkyl, where the phenyl ring is not substituted or is mono- or disubstituted with (lower)alkoxy or halide, pyridyl which is mono- or disubstituted with a halide, and NR3R4 or when Z is C(O), R2 can also be a (lower)alkoxy; R3 is hydrogen or (lower)alkyl; R4 is selected from a group consisting of (lower)alkyl, (lower)alkoxyalkyl, (C3-C7)cycloalkyl, unsubstituted phenyl or phenyl which is mono-substituted with (lower)alkoxy, or (lower)phenylalkyl, where phenyl is not substituted or is mono- or disubstituted with a halide; or R3 and R4 together with the nitrogen atom to which they are bonded form a 5-, 6- or 7-member heterocyclic ring which optionally contains an additional heteroatom selected from oxygen, the said heterocyclic ring is unsubstituted or substituted with one or two groups independently selected from (lower)alkyl, halide and alkyl halide, or is condensed with a phenyl or cyclohexyl ring, and to their pharmaceutically acceptable salts, as well as to pharmaceutical compositions containing these compounds. ^ EFFECT: obtaining novel compounds and pharmaceutical compositions based on the said compounds, which are suitable for treating and/or preventing diseases which are associated with modulation of H3 receptors. ^ 25 cl, 2 tbl, 93 ex Изобретение относится к соединениям формулы (I) ! ! где R означает водород или (низш.)алкил; R1 означает (низш.)алкил или (С3-С7)циклоалкил; Х означает азот, a Y означает углерод или Y означает азот, а Х означает углерод; m означает 0 или 1; Z означает С(O) или SO2; R2 выбирают из группы, состоящей из (низш.)алкила, (С3-С7)циклоалкила или (С3-С7)циклоалкила, замещенного (низш.)алкилом, (низш.)фенилалкила, где фенильное кольцо является незамещенным или моно- или дизамещенным (низш.)алкокси или галоидом, пиридила, моно-или дизамещенного галоидом, и NR3R4 или в случае, когда Z означает С(O), R2 может быть также (низш.)алкокси; R3 означает водород или (низш.)алкил; R4 выбирают из группы, состоящей из (низш.)алкила, (низш.)алкоксиалкила, (С3-С7)циклоалкила, незамещенного фенила или фенила, монозамещенного (низш.)алкокси, или (низш
