We have developed versatile methods toward the synthesis of a variety of piperidine/piperazine bridged isosteres of pridopidine. The compounds were assessed against the D2 receptor in agonist and antagonist modes and against the D4 receptor in agonist mode. hERG Binding and the ADME profiles were studied.

Page/Page column 62, (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.

Discovering dopamine D2-like receptor subtype-selective ligands has been a focus of significant investigation. The D2R-selective antagonist 3-[4-(4-chlorophenyl)-4-hydroxypiperidinyl]methylindole (1, L741,626; K i(D2R/D3R) = 11.2:163 nM) has previously provided a lead template for chemical modification. Herein, analogues have been synthesized where the piperidine was replaced by a tropane ring that reversed the selectivity seen in the parent compound, in human hD2LR- or hD3R-transfected HEK 293 cells (31, Ki(D2R/D3R) = 33.4: 15.5 nM). Further exploration of both N-substituted and aryl ring-substituted analogues resulted in the discovery of several high affinity D2R/D3R ligands with 3-benzofurylmethyl-substituents (e.g., 45, Ki(D2R/D3R) = 1.7:0.34 nM) that induced high affinity not achieved in similarly N-substituted piperidine analogues and significantly (470-fold) improved D3R binding affinity compared to the parent ligand 1. X-ray crystallographic data revealed a distinctive spatial arrangement of pharmacophoric elements in the piperidinol vs tropine analogues, providing clues for the diversity in SAR at the D2 and D3 receptor subtypes.

2,3-Dihydro-1,4-benzodioxanes with aryl 8-aza-bicyclo[3.2.1]oct-3-ene attachments 2 produce compounds with potent 5-HT-T affinity, and weak 5-HT 1A affinity and α1 affinity. This compares with 2,3-dihydro-1,4-benzodioxanes containing 8-aza-bicyclo[3.2.1] octan-3-ol attachments 4 which possess potent 5-HT1A affinity, moderate to good selectivity over α1 and little 5-HT-T affinity. A 3-benzothiophene analogue of 4 (30) was synthesized which possesses potent 5-HT1A affinity and especially good selectivity over both α1 and 5-HT-T.
