Design, Synthesis, and Neurochemical Evaluation of 5-(3-Alkyl-1,2,4-oxadiazol-5-yl)-1,4,5,6-tetrahydropyrimidines as M1 Muscarinic Receptor Agonists

A series of 5-(3-alkyl-1,2,4-oxadiazol-5-yl)-1,4,5,6-tetrahydropyrimidines (7a-h) was synthesized for biological evaluation as selective agonists for M1 receptors coupled to phosphoinositide (PI) metabolism in the central nervous system.Each ligand bound with high affinity to muscarinic receptors from rat brain as measured by inhibition of <3H>-(R)-quinuclidinyl benzilate (<3H>-(R)-QNB) binding. 5-(3-Methyl-1,2,4-oxadiazol-5-yl)-1,4,5,6-tetrahydropyrimidine trifluoroacetate (CDD-0098-J; 7a)displayed high affinity (IC50 = 2.7 +/- 0.69 muM) and efficacy at muscarinic receptors coupled to PI metabolism in the rat cortex and hippocampus .Increasing the length of the alkyl substituent increased affinity for muscarinic receptors yet decreased activity in PI turnover assays.The hippocampal PI response of 7a was blocked by lower concentrations of pirenzepine (8) or by higher concentrations of either AF-DX 116 (9) or p-fluorohexahydrosiladifenidol (10), suggesting that a low concentrations 7a selectively stimulates PI turnover through M1 receptors.

Design, synthesis, structure-activity relationship, and in vivo activity of azabicyclic aryl amides as alpha7 nicotinic acetylcholine receptor agonists

A novel set of azabicyclic aryl amides have been identified as potent and selective agonists of the alpha7 nAChR. A two-pronged approach was taken to improve the potential hERG liability of previously disclosed alpha7 nAChR agonist, PNU-282,987, while maintaining the compound’s other desirable pharmacological properties. The first approach involved further exploration of the aryl carboxylic acid fragment of PNU-282,987, while the second approach focused on modification of the azabicyclic amine portion of PNU-282,987. The best compounds from each series are characterized by rapid brain penetration, good oral bioavailability in rat, and demonstrate in vivo efficacy in a rat P50 auditory sensory gating assay. At least one analog from each series (1h, 1o, 2a, 9a, and 18a) shows an improved hERG safety profile over PNU-282,987.

Estimation of agonist activity at g protein-coupled receptors: Analysis of M2 muscarinic receptor signaling through Gi/o, G s, and G15

We developed novel methods for analyzing the concentrationresponse curve of an agonist to estimate the product of observed affinity and intrinsic efficacy, expressed relative to that of a standard agonist. This parameter, termed intrinsic relative activity (RAi), is most applicable for the analysis of responses at G protein-coupled receptors. RAi is equivalent to the potency ratios that agonists would exhibit in a hypothetical, highly sensitive assay in which all agonists behave as full agonists, even those with little intrinsic efficacy. We investigated muscarinic responses at the M2 receptor, including stimulation of phosphoinositide hydrolysis through Galpha15 in HEK 293T cells, inhibition of cAMP accumulation through Gi in Chinese hamster ovary (CHO) cells, and stimulation of cAMP accumulation through Gs in CHO cells treated with pertussis toxin. The RAi values of carbachol, oxotremorine-M, and the enantiomers of aceclidine were approximately the same in the three assay systems. In contrast, the activity of 4-[[N-[3-chlorophenyl]carbamoy] oxy-2-butynyl]trimethylammonium chloride (McN-A-343) was ?10-fold greater at M2 receptors coupled to Galpha15 in HEK 293T cells compared with M2 receptors coupled to Gi in the same cells or in CHO cells. Our results show that the RAi estimate is a useful measure for quantifying agonist activity across different assay systems and for detecting agonist directed signaling. Copyright

A practical chemoenzymatic process to access (R)-quinuclidin-3-ol on scale

(¡À)-3-Butyryloxyquinuclidinium butyrate 6 (2 M, 571 g/L), prepared from (¡À)-quinuclidin-3-ol 1 and butyric anhydride, undergoes enantioselective hydrolysis by an Aspergillus melleus protease {1.0% (w/v)} in water in the presence of Ca(OH)2 to keep the reaction at pH 7 and trap butyric acid that is introduced as part of (¡À)-6 and generated by the enzymatic hydrolysis. After a 24 h period, extraction with n-heptane provides (R)-quinuclidin-3-yl butyrate 5a, which, on methanolysis with Na2CO3, is converted into (R)-1, a common pharmacophore of neuromodulators acting on muscarinic receptors, in 96% ee and 42% overall yield from (¡À)-1. The unwanted antipode (S)-1, which is extracted into n-butanol and purified via its hydrochloride salt in 89% ee and 40% overall yield from (¡À)-1, can be racemized by the catalysis of Raney Co at 140C under an atmosphere of H2 (5 kg/cm2) to regenerate (¡À)-1 in 97% yield.
