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.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 2495-37-6. Product Details of 2495-37-6.

A direct, short chiral synthesis of the selective 0 nicotinic receptor agonist (-)-spiro[l-azabicyclo[2.2.2]octane-3,5′-oxazolidin-2′-one] (AR-R17779) is presented. The key step utilized attack of the dianion of the (R)-HYTRA ester [(R)-(+)-2-hydroxy-1,2,2-triphenylethyl acetate] on quinuclidin-3-one, followed by a selective precipitation of the diasteriomeric tertiary alcohol that led to (S)-(-)-AR-R17779 in two additional steps.

Quantitation of muscarinic receptors in the lungs in vivo with positron emission tomography (PET) is of clinical interest. For that purpose we decided to develop [C-11]-labeled ligands with a high affinity (K-D < 0.1 nM). Three quaternary muscarinic antagonists, racemic N-methylpiperidin-4-yl 2-cyclohexy-2-2-hydroxy-2-phenylacetate methiodide 1a (pK(B) = 10.39), its (R)-isomer 1b (pK(B) = 11.08), and (R,R)-quinuclidin-3-yl 2-cyclohexyl-2-hydroxy-2-phenylacetate methiodide 2 (pK(B) = 11.28), were labeled by reacting [C-11]CH3I With their tertiary amine precursors. The enantiomerically pure tertiary amine precursors were prepared by stereoselective synthesis starting from (R)-(-)-mandelic acid. In vitro binding assay of 1b and 2 demonstrated that both ligands bind with very high affinity to the muscarinic receptor subtypes M(1), M(2), and M(3). They are more potent than the muscarinic antagonist (R)-N-methylquinuclidinyl benzilate ((R)-MQNB). Distribution studies with la, 1b, and 2 in control and atropine-treated male Wistar rats demonstrated significant specific binding (90-99% of total issue uptake) in tissues containing cholinoceptors (heart, intestine, lung, pancreas, spleen, stomach, submandibular gland). Because the tissue/plasma concentration ratios of 1b are most favorable, this ligand was used for further evaluation. Analysis of plasma samples showed a very rapid clearance (t(1/2) = 0.3 min) of the radioligand 1b and a relatively slow appearance of a hydrophilic metabolite. At 15 min postinjection of 1b, analysis of heart, lungs, and liver showed that respectively 99%, 88%, and 8% of the tissue radioactivity corresponded with the parent compound. Ligand 1b appears to be an excellent candidate for PET studies of mAChR receptors in heart and lungs. Category: quinuclidines, I am very proud of our efforts over the past few months and hope to 2495-37-6 help many people in the next few years.

Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. Application In Synthesis of Benzyl methacrylate.

This contribution introduces a fluorescence assay for real-time determination of the activity of p97/VCP, a 540-kDa homo-hexameric enzyme, belonging to the AAA-ATPase family. A fluorescent reporter poly 1-(3-((4-methylthiophen-3-yl)oxy)propyl)quinuclidin-1-ium (poly PTQ) is used to monitor the hydrolysis of ATP to ADP by p97/VCP. The proposed assay relies on the different strength of coordination of ATP and ADP to the polymer backbone. We used recovery of fluorescence intensity on addition of p97/VCP to a poly PTQ/ATP solution to determine the enzymatic activity. The kinetic data K (m) and V (max) were 0.30 mmol L-1 ATP and 0.134 nmol ATP min(-1) mu g(-1) enzyme, respectively. The specificity of the assay was investigated by using an unhydrolyzable ATP analogue and sensitivity against p97 mutagenesis was further examined by detection of the activity of wild type and truncated p97/VCP. Our study demonstrates that determination of the real-time activity of p97/VCP is possible, because of the superior sensitivity and very fast optical response of poly PTQ.
