Page/Page column 68, (2011/04/19)
The present invention pertains generally to the field of therapeutic compounds. More specifically the present invention pertains to certain (4-phenyl-piperidin-1-yl)- [5-(1 H-pyrazol-4-yl)-thiophen-3-yl]-methanone compounds that, inter alia, inhibit 11 β-hydroxysteroid dehydrogenase type 1 (11 β-HSD1 ). The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit 1 1 β-hydroxysteroid dehydrogenase type 1; to treat disorders that are ameliorated by the inhibition of 11 β-hydroxysteroid dehydrogenase type 1; to treat the metabolic syndrome, which includes disorders such as type 2 diabetes and obesity, and associated disorders including insulin resistance, hypertension, lipid disorders and cardiovascular disorders such as ischaemic (coronary) heart disease; to treat CNS disorders such as mild cognitive impairment and early dementia, including Alzheimer's disease; etc.

We synthesized methylvesamicol analogs 13-16 and investigated the binding characteristics of 2-[4-phenylpiperidino]cyclohexanol (vesamicol) and methylvesamicol analogs 13-16, with a methyl group introduced into the 4-phenylpiperidine moiety, to sigma receptors (σ-1, σ-2) and to vesicular acetylcholine transporters (VAChT) in membranes of the rat brain and liver. In competitive inhibition studies, (-)-o-methylvesamicol [(-)-OMV] (13) (Ki = 6.7 nM), as well as (-)-vesamicol (Ki = 4.4 nM), had a high affinity for VAChT. (+)-p-Methylvesamicol [(+)-PMV] (16) (Ki = 3.0 nM), as well as SA4503 (Ki = 4.4 nM), reported as a σ-1 mapping agent for positron emission tomography (PET), had a high affinity for the σ-1 receptor. The binding affinity of (+)-PMV (16) for the σ-1 receptor (Ki = 3.0 nM) was about 13 times higher than that for the sigma-2 (σ-2) receptor (Ki = 40.7 nM). (+)-PMV (16) (K i = 199 nM) had a much lower affinity for VAChT than SA4503 (K i = 50.2 nM) and haloperidol (Ki = 41.4 nM). These results showed that the binding characteristics of (-)-OMV (13) to VAChT were similar to those of (-)-vesamicol and that (+)-PMV (16) bound to the σ-1 receptor with high affinity. In conclusion, (-)-OMV (13) and (+)-PMV (16), which had a suitable structure, with a methyl group for labeling with 11C, may become not only a new VAChT ligand and a new type of σ receptor ligand, respectively, but may also become a new target compound of VAChT and the σ-1 receptor radioligand for PET, respectively.
