Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, Like 22767-49-3, Name is Sodium pentane-1-sulfonate. In a document, author is Lee, Na-Ra, introducing its new discovery. Category: quinuclidines.
Muscarinic agonist, ( +/- )-quinuclidin-3-yl-(4-fluorophenethyl)(phenyl) carbamate: High affinity, but low subtype selectivity for human M-1 – M-5 muscarinic acetylcholine receptors
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.
One of the oldest and most widely used commercial enzyme inhibitors is aspirin, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. 22767-49-3, you can contact me at any time and look forward to more communication. Category: quinuclidines.
