FIELD: medicine, pharmaceutics.
SUBSTANCE: invention relates to new derivatives of piperidine of formula I: 
, in which: R1 and R2 are selected from group, including alkyl, halogenalkyl, alkyl substituted with one or more hydroxy groups, -CN, alkynyl, -N(R6)2, - N(R6)-S(O2)-alkyl, -N(R6)-C(O)-N(R9)2, -alkylene-CN, -cycloalkylene-CN, -alkylene-O-alkyl, -C(O)-alkyl, -C(=N-OR5)-alkyl, -C(O)-O-alkyl, -alkylene-C(O)-alkyl, -alkylene-C(O)-O-alkyl, -alkylene-C(O)-N(R9)2 and group 
, 
, 
, 
,
provided that at least one of R1 and R2 stands for -CN or group 
, 
, 
, 
,
W stands for =C(R8)- or =N-; X stands for -C(O)- or -S(O2)-; Y is selected from group, including -CH2-, -O- and -N(R6)-C(O)-, provided that: (a) atom of nitrogen of group -N(R6)-C(O)- is linked with X, and (b) if R1 and/or R2 stands for 
and Y stands for -O-, then X does not stand for -S(O2)-; Z stands for -C(R7)2-, -N(R6)-, or -O-; R3 is selected from group, including H and non-substituted alkyl; R4 stands for H; R5 stands for H or alkyl; R6 is selected from group, including H, alkyl, cycloalkyl and aryl; each R7 independently stands for H or alkyl; or each R7 together with circular atom of carbon, to which they are linked, as indicated, forms cycloalkylene ring; R8 is selected from group including H, alkyl, alkyl substituted with one or large number of hydroxygroups, -N(R6)2, -N(R6)-S(O2)- alkyl, -N(R6)-S(O2)-aryl, -N(R6)-C(O)-alkyl, -N(R6)-C(O)-aryl, alkylene-O-alkyl and -CN; R9 is selected from group including H, alkyl and aryl, or each R9 jointly with atom of nitrogen, to which, as indicated, they are linked, forms heterocycloalkyl ring; Ar1 stands for non-substituted phenyl; Ar2 stands for phenyll substituted with 0-3 substituents, selected from group including halogenalkyl; n equals 0, 1 or 2; and m equals 1, 2 or 3, and to their pharmaceutically acceptance salts and hydrates.
EFFECT: production of new biologically active compounds, having properties of antagonist of neurokinin receptor NK1.
