Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner.In an article, author is Bosak, A, once mentioned the application of 7779-30-8, Name is 1-(2,6,6-Trimethylcyclohex-2-en-1-yl)pent-1-en-3-one, molecular formula is C14H22O, molecular weight is 206.32, MDL number is MFCD00031478, category is quinuclidines. Now introduce a scientific discovery about this category, Recommanded Product: 1-(2,6,6-Trimethylcyclohex-2-en-1-yl)pent-1-en-3-one.
Enantiomers of quinuclidin-3-ol derivatives: Resolution and interactions with human cholinesterases
The (R)- and (S)-enantiomers of quinuclidin-3-ol and quinuclidin-3-yl acetate as well as their quaternary N-methyl and N-benzyl derivatives were synthesized in order to study the stereo-selectivity of human erythrocyte acetylcholinesterase (EC 3.1.1.7) and plasma butyrylcholinesterase (EC 3.1.1.8). The compounds were tested as substrates and inhibitors of cholinesterases. Both cholinesterases hydrolyze the derivatives of quinuclidin-3-yl acetate with a preference for the (R)- over (S)-enantiomers. In contrast to the hydrolysis of the enantiomers of acetates, the inhibition of acetylcholinesterase and butyrylcholinesterase by the (R)- and (S)-enantiomers of quinuclidin-3-ol derivatives does not reveal enantiomeric preference of the enzymes. The (R)and (S)-acetates also act as nonstereoselective inhibitors of the enzyme-induced hydrolysis of acetylthiocholine. The best substrate is (R)-N-methyl-3-acetoxyquinuclidinium iodide with k(cat) = 1.5 x 10(6) min(-1) and k(cat) = 5.5 x 10(4) min(-1) for acetylcholinesterase and butyrylcholinesterase, respectively. The (R)- and (S)-N-benzylquinuclidinium derivatives are the most potent inhibitors of both enzymes.
Each elementary reaction can be described in terms of its molecularity, the number of molecules that collide in that step. The slowest step in a reaction mechanism is the rate-determining step.Interested yet? Keep reading other articles of 7779-30-8, you can contact me at any time and look forward to more communication.
