The present invention relates to compounds of formula (I): STR1 wherein m is zero, 1 or 2; and n is zero or 1, with the proviso that the sum total of m+n is 1 or 2; R1 represents phenyl; naphthyl; benzhydryl; or benzyl, where the naphthyl group or any phenyl moiety may be substituted; R2 represents hydrogen; phenyl; heteroaryl selected from indazolyl, thienyl, furanyl, pyridyl, thiazolyl, tetrazolyl and quinolinyl; naphthyl; benzhydryl; or benzyl; wherein each heteroaryl, the naphthyl group and any phenyl moiety may be substituted; R3 and R4 each independently represents hydrogen or C1-6 alkyl or R3 and R4 together are linked so as to form a C1-3 alkylene chain; Q represents CR5 R6 or NR5 ; X and Y each independently represents hydrogen, or together form a group =O; and Z represents a bond, O, S, SO, SO2, NRc or --(CRc Rd)--, where Rc and Rd each independently represent hydrogen or C1-6 alkyl; or a pharmaceutically acceptable salt thereof. The compounds are of particular use in the treatment or prevention of pain, inflammation, migraine, emesis and postherpetic neuralgia.
Spiropiperidines as high-affinity, selective σ ligands

A variety of achiral conformationally restricted spirocyclic piperidines have been prepared in an attempt to investigate the functional role of the central σ recognition site. All the compounds possessed a lipophilic N- substituent incorporating either a tetralin, indan, or benzocycloheptane skeleton. Their in vitro affinity at the σ site was assessed in radioligand displacement experiments with guinea pig cerebellum homogenates using the σ- specific radioligand [3H]-N,N'-di-o-tolylguanidine ([3H]-DTG, [3H]-6). A study of the structure-activity relationships identified the N-butyl and N- dimethylallyl substituents as the optimum groups for high affinity and selectivity at the σ site (e.g., 3,4-dihydro-1'-(3-methylbut-2- enyl)spiro[1H-indene-1,4'-piperidine] (48), pIC50 = 8.9 vs [3H]-6 and greater than 10 000-fold selective over the dopamine D2 receptor). Such compounds are amongst the highest affinity σ ligands reported to date, with excellent selectivity over the dopamine D2 receptor, and may serve as a useful tool for exploring the physiological role of the σ site.
