The novel alpha 7 nicotinic acetylcholine receptor agonist EVP-6124 enhances dopamine, acetylcholine, and glutamate efflux in rat cortex and nucleus accumbens

Background Alpha7 and alpha 4 beta 2 nicotinic acetylcholine receptor (nAChR) agonists have been shown to improve cognition in various animal models of cognitive impairment and are of interest as treatments for schizophrenia, Alzheimer’s disease, and other cognitive disorders. Increased release of dopamine (DA), acetylcholine (ACh), glutamate (Glu), and gamma-aminobutyric acid (GABA) in cerebral cortex, hippocampus, and nucleus accumbens (NAC) has been suggested to contribute to their beneficial effects on cognition. Results Using in vivo microdialysis, we found that EVP-6124 [(R)-7-chloro-N-quinuclidin-3-yl) benzo[b] thiophene-2-carboxamide], a high-affinity alpha 7 nAChR partial agonist, at 0.1 mg/kg, s.c., increased DA efflux in the medial prefrontal cortex (mPFC) and NAC. EVP-6124, 0.1 and 0.3 mg/kg, also increased efflux of ACh in the mPFC but not in the NAC. Similarly, EVP-6124, 0.1 mg/kg, but not 0.03 and 0.3 mg/kg, significantly increased mPFC Glu efflux. Thus, EVP-6124 produced an inverted U-shaped curve for DA and Glu release, as previously reported for other alpha 7 nAChR agonists. The three doses of EVP-6124 did not produce a significant effect on GABA efflux in either region. Pretreatment with the selective alpha 7 nAChR antagonist, methyllycaconitine (MLA, 1.0 mg/kg), significantly blocked cortical DA and Glu efflux induced by EVP-6124 (0.1 mg/kg), suggesting that the effects of EVP-6124 on these neurotransmitters were due to alpha 7 nAChR agonism. MLA only partially blocked the effects of EVP-6124 on ACh efflux in the mPFC. Conclusion These results suggest increased cortical DA, ACh, and Glu release, which may contribute to the ability of the alpha 7 nAChR agonist, EVP-6124, to treat cognitive impairment and possibly other dimensions of psychopathology.

Intramolecular palladium-catalyzed allylic alkylation: Enantio- and diastereoselective synthesis of [2.2.2] bicycles

[GRAPHICS] Pd-catalyzed asymmetric allylic alkylation provides both enantio- and diastereoselectivity in formation of bicyclo [2.2.2] octan-2,3-diones and quinuclidin-2-ones, the latter potential precursors to quinine alkaloids.
