Compounds of formula (I) and their use in therapy, particularly for the treatment of a disorder mediated by CB1 receptors, such as obesity, wherein: R1 is aryl or heteroaryl; R2 is alkyl, aryl or heteroaryl; R3 is alkyl, aryl, heteroaryl, NR9R10, OR 15, or NR16C(O)R17;Y is C=O, C=S, SO2, or (CR7R8)p; m = 1 or 2; n = 1 or 2; and p=1,2,3 or 4, R7 to R17 being as defined in the specification; wherein if -Y-R3 is -C(O)NH(alkyl) then: R1 and/or R2 is selected from heteroary1; and/or m and/or n is 2; and/or R11 and/or R12 is lower alkyl, or a pharmaceutically acceptable salt or prodrug thereof.

A simple method of transforming classical antihistaminics into nonsedative antiallergic agents with strong effects in rat models is described. Various [4-(diphenylmethoxy)piperidinol - (series A), [4-(diphenylmethyl)piperazinyl]- (series B) and [4-(diphenylmethylene)piperidino]alkanoic acid derivatives (series C) were synthesized and examined for antiallergic activities and effects on the central nervous system (CNS), in comparison with the corresponding N-methyl derivatives (1a-c). N-Alkylcarboxylic acids (5a-c) showed stronger inhibitory effects on compound 48/80-induced lethality in rats than the corresponding N-methyl derivatives (1a-c). In particular, N-alkylcarboxylic acids (5a) in series A exhibited approximately 100-fold stronger inhibitory effects than 1a, and were the least effective in prolonging the sleeping time on hexobarbital-induced anesthesia in mice in all series. As a result of chemical modification in series A, it was found that introduction of a methyl group at the para-position on one benzene ring in the (diphenylmethoxy)piperidine system effectively reduced CNS side-effects without reducing antiallergic activity. (+)-3-[4-[(4-Methylphenyl)phenylmethoxy] piperidinol propionic acid ((+)-51), an optically active isomer of 51, exhibited a stronger antiallergic effect (ED50 = 0.17 mg/kg, p.o.) than ketotifen and terfenadine in the 48 h homologous passive cutaneous anaphylaxis (PCA) test, and moreover exhibited no CNS side-effects, such as prolongation of the sleeping time on hexobarbital-induced anesthesia, at an oral dose of 30 mg/kg. Compound (+)-51 was thus proved to be a promising candidate as a nonsedative antiallergic agent.
