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.

The lead compound of a new series of azabicyclic carbamates described by Astra Laboratories as ligands for the alpha7 nicotinic acetylcholine receptor subtype, namely N-(4-bromophenyl)carbamic acid quinuclidin-3-yl ester, has been labelled with carbon-11 using no-carrier-added [C-11]phosgene and the isocyanate pathway. Typically, 25-35 mCi (0.92-1.29 GBq) of the tracer was obtained within 30 min of radiosynthesis (HPLC purification included) with specific radioactivities ranging from 500 to 800 mCi/mu mol (18.5-29.6 GBq/mu mol). Biodistribution studies demonstrated a relatively good brain uptake of the compound (0.8-1.2% I.D./g tissue in various brain regions), but without preferential concentration in brain regions rich in alpha7-subtype nicotinic receptor (e.g. hippocampus, pons and colliculi). No specific binding could be demonstrated in pre-saturation studies performed with both the cold compound and nicotine. Therefore, this ligand is not suitable for further exploration in PET imaging.

Research speed reading in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. Like 707-37-9, Name is 1-Hydroxy-3,5-dimethyladamantane. In a document, author is Lee, Na-Ra, introducing its new discovery. Application In Synthesis of 1-Hydroxy-3,5-dimethyladamantane.

Novel quinuclidinyl N-phenylcarbamate analogs were synthesized, and binding affinities at M-1-M-5 muscarinic acetylcholine receptor (mAChR) subtypes were determined using Chinese hamster ovary (CHO) cell membranes stably expressing one specific subtype of human mAChR. Although not subtype selective, the lead analog ( +/- )-quinuclidin-3-yl-(4-fluorophenethyl)(phenyl)carbamate (3c) exhibited the highest affinity (K-i = 2.0, 13, 2.6, 2.2, 1.8 nM) at each of the M-1-M-5 mAChRs, respectively. Based on results from the [H-3]dopamine release assay using rat striatal slices, 3c acted as an agonist at mAChRs. The effect of 3c was inhibited by the nonselective mAChR antagonist, scopolamine, and 3c augmented release evoked by oxotremorine. A potent analog from the same scaffold, ( +/- )-quinuclidin-3-yl-(4-methoxyphenethyl)(phenyl)-carbamate (3b) exhibited the greatest selectivity (17-fold) at M-3 over M-2 mAChRs. These analogs could serve as leads for further discovery of novel subtype-selective muscarinic ligands with the goal of providing therapeutics for substance use disorders and chronic obstructive pulmonary disease.
