- Bioisosteric replacement and related analogs in the design, synthesis and evaluation of ligands for muscarinic acetylcholine receptors
-
Previous structure-activity relationship studies involving a series of lactone-based muscarinic ligands identified a lead compound containing a diphenylmethylpiperazine moiety (4; IC50 = 340 nM). The purpose of the present work is to investigate 1,3-benzodioxoles, 4,4-diethyl substituted tetrahydrofurans, 5-substituted oxazolidinones and chromones as bioisosteric replacements for the lactone ring in a novel series of muscarinic ligands. The approach provided compounds with improved % inhibition values and identified a non-selective muscarinic ligand with an IC50 value of 280 nM. The structure-activity relationship for this new series will be discussed. Selected compounds were evaluated in preliminary assays for subtype selectivity and were found to be non-selective.

- Synthesis and binding affinities of methylvesamicol analogs for the acetylcholine transporter and sigma receptor
-
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.

- Efficient Solution-Phase Parallel Synthesis of 4-Substituted N-Protected Piperidines
-
Practical conditions for the synthesis of 4-substituted N-protected piperidines through CuCN·2LiBr-catalyzed organozinc additions to 1-acylpyridinium salts and subsequent hydrogen-transfer hydrogenation have been established. The reaction sequence is performed at room temperature and provides 4-substituted N-protected piperidines in excellent overall yields without the isolation of intermediate dihydropyridines, In those cases in which the organozinc addition results in mixtures of 2- and 4-substituted dihydropyridines, the 2-substituted isomers are efficiently scavenged with maleic anhydride and subsequently removed by a mild extractive workup with NaHCO3 (sat.). The N-acyl group can conveniently be exchanged from N-phenoxycarbonyl to N-tBoc, thus allowing orthogonal deprotection strategies. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
