The development of an efficient and economic one-pot process, in which the configuration of the chiral centers of the starting materials is retained, for the preparation of highly pure solifenacin succinate, an antimuscarinic agent, is presented in this communication. The earlier reported processes suffer from the drawbacks of racemization and low yields due to the use of strong base, higher temperatures, and longer reaction times. The present work circumvents these issues by activating (3R)-quinuclidin-3-ol into a mixed active carbonate derivative by treating it with bis(4-nitrophenyl)carbonate. The subsequent reaction of the active carbonate with an enantiomerically pure amine without using any base at ambient temperature provided enantiomerically pure solifenacin with an overall yield of 90%.

In a article, author is Liu, Shenping, introduce new discover of the category.

Nicotinic acetylcholine receptors (nAChRs) form ligand-gated ion channels that mediate fast signal transmission at synapses. These receptors are members of a large family of pentameric ion channels that are of active medical interest. An expression system utilizing a chimerical construct of the N-terminal extracellular ligand binding domain of alpha7 type nAChR and the C-terminal transmembrane portion of 5HT3 type receptor resulted high level of expressions. Two ligand affinity chromatography purification methods for this receptor have been developed. One method relies on the covalent immobilization of a high affinity small molecule alpha7 nAChR agonist, (R)-5-(4-aminophenyl)-N-(quinuclidin-3-yl) furan-2-carboxamide, and the other uses mono biotinylated alpha-bungarotoxin, an antagonist, that forms a quasi-irreversible complex with alpha7 nAChR. Detergent solubilized alpha7/5HT(3) chimeric receptors were selectively retained on the affinity resins and could be eluted with free ligand or biotin. The proteins purified by both methods were characterized by gel electrophoresis, mass spectra, amino acid composition analysis, and N-terminal sequence determination. These analyses confirmed the isolation of a mature alpha7/5HT(3) receptor with the signal peptide removed. These results suggest a scalable path forward to generate multi-milligram amounts of purified complexes for additional studies including protein crystallization. (C) 2011 Elsevier Inc.

Racemates as well as (R)- and (S)-enantiomers of 3-pivalamidoquinuclidine (PivQ) and 3-acetamidoquinuclidine (AcQ) were prepared. Their quaternary racemic and enantiomerically pure N-benzyl derivatives (BnlPivQ and BnlAcQ) were synthesized as well. The amides were tested as substrates and inhibitors of butyrylcholinesterase (BChE) from horse serum (EC 3.1.1.8). No hydrolysis was observed under the experimental conditions applied. On the contrary, inhibition of BChE by (R)- and (S)-enantiomers of N-benzylquinuclidinium amides of pivalic acid was observed. The (S)-BnlPivQ with K-i = 41.57 mu mol dm(-3) was 3-fold more potent inhibitor than the (R)-enantiomer. On the other hand, preliminary results indicated that both enantiomers of N-benzylquinuclidinum amides of acetic acid may possibly be inhibitors as well as activators depending on the concentrations of benzoylcholine (BzCh) used as a substrate of BChE.

Like 7779-30-8, Name is 1-(2,6,6-Trimethylcyclohex-2-en-1-yl)pent-1-en-3-one. In a document, author is Ford, Benjamin M., introducing its new discovery. Electric Literature of 7779-30-8.

Most cannabinoid 1 receptor (CB1R) agonists will signal through both G protein-dependent and -independent pathways in an unbiased manner. Recruitment of beta-arrestin 2 desensitizes and internalizes receptors, producing tolerance that limits therapeutic utility of cannabinoids for chronic conditions. We developed the indole quinuclidinone (IQD) analog (Z)-2-((1-(4-fluorobenzyl)1H-indol-3-yl)nnethylene)quinuclidin-3-one (PNR-4-20) as a novel G protein-biased agonist at CB(1)Rs, and the present studies determine if repeated administration of PNR-4-20 produces lesser tolerance to in vivo effects compared with unbiased CB1R agonists, Delta(9)-tetrahydrocannabinol (Delta(9)-THC) and 1-pentyl-3-(1-naphthoyl)indole (JWH-018). Adult male National Institutes of Health Swiss mice were administered comparable doses of PNR-4-20 (100 mg/kg), Delta(9)-THC (30 mg/kg), or JWH-018 (3 mg/kg) once per day for five consecutive days to determine tolerance development to hypothermic, antinociceptive, and cataleptic effects. Persistence of tolerance was then determined after a drug abstinence period. We found that unbiased CB1R agonists Delta(9)-THC and JWH-018 produced similar tolerance to these effects, but lesser tolerance was observed with PNR-4-20 for hypothermic and cataleptic effects. Tolerance to the effects of PNR-4-20 completely recovered after drug abstinence, while residual tolerance was always observed with unbiased CB1R agonists. Repeated treatment with PNR-4-20 and Delta(9)-THC produced asymmetric cross-tolerance to hypothermic effects. Importantly, binding studies suggest PNR-4-20 produced significantly less down-regulation of CB(1)Rs relative to Delta(9)-THC in hypothalamus and thalamus of chronically treated mice. These studies suggest that the G protein-biased CB1R agonist PNR-4-20 produces significantly less tolerance than unbiased cannabinoid agonists, and that the IQD analogs should be investigated further as a novel molecular scaffold for development of new therapeutics.

Me-QNB (N-methyl-quinuclidin-3-yl benzilate or N-methyl-quinuclidin-3-yl diphenylhydroxy acetate) is a hydrophilic, non-metabolized and highly specific muscarinic acetylcholinergic antagonist. Using this quaternary ammonium derivative of QNB, labelled with carbon-11, a positron-emitting isotope (half-life : 20.4 minutes), the potential for quantification of myocardial muscarinic receptors in vivo using the high-resolution, sensitive and quantitative imaging technique PET (positron emission tomography) was previously demonstrated in dogs and validated in humans. In this paper, the radiosynthesis of carbon-11-labelled Me-QNB is investigated and oriented towards the preparation of multi milliCuries of radiotracer. Typically, using no-carrier-added [C-11]methyl triflate as the alkylating agent and 0.64 mg (1.89 mu mol) of QNB as precursor for labelling at 100 degreesC for 1 minute lead to a 48.5% +/- 10% (15 runs) decay-corrected radiochemical yield (based on [C-11]methyl triflate). 183 mCi (+/- 39) of [C-11]Me-QNB ([C-11]-1) could be synthesized in only 27 to 28 minutes after EOB and occasionally, up to 340 mCi of [C-11]Me-QNB ([C-11]-1) were obtained, corresponding to a 85% decay-corrected yield. The associated decay-corrected specific radioactivities obtained were 2658 mCi/mu mol (+/- 971) at EOB.
