New piperidine derivatives are disclosed having the following general formula:
wherein Y is a group represented by R10 or
R10 is hydrogen, alkyl having 1 - 3 carbon atoms, or substituted or unsubstituted benzyl, and when Y is
Q is H; m is 0 or an integer of 1 - 5; A is hydroxyl, halogen, C1-C5 alkyl, C1-C5 alkoxy, C2-C5 alkenyloxy, C2-C5 alkinyloxy, C1-C5 alkylthio, carboxyl, C1-C5 alkoxycarbonyl, nitro, amino, C1-C5 alkylamino, C1-C5 alkanoylamino, sulfamoyl, mono or di-(CI-C5 alkyl) aminosulfonyl, C1-C5 alkylsulfonyl, carbamoyl, cyano or trifluoromethyl; when m is 2 or more, the A groups may be the same or different, or two A groups may be combined to form a C1-C5 alkylenedioxy group; X is oxygen, sulfur, carbonyl, hydroxymethylene or methylene; R is straight-chain alkylene having 1 - 4 carbon atoms, or straight-chain alkylene having 1 - 4 carbon atoms and having a C1-C5 alkyl substituent; Q is hydrogen, C1-C5 alkyl, halogen, hydroxyl or C1-C5 alkanoyloxy; n is 0 or an integer of 1 - 4; R2 is hydroxyl, C1-C5 alkoxy, halogen, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, nitro or amino; when n is 2 or more, the R2 groups may be the same or different, or two R2 groups may by combined to form a C1-C5 alkylenedioxy; B is -NH-, -N(R)- (wherein R is C1-C5 alkyl, or substituted or unsubstituted phenyl) or -0-; and acid addition salts thereof.
The new piperidine derivatives wherein Y is
have a hypotensive activity.
