80841-78-7,Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. Which mentioned a new discovery about 80841-78-7.
A solution containing about 46 g of compound 4 was taken, 3.5g sodium iodide was added, 280 mL N, N-dimethylformamide, 11.2g DMDO-Cl was slowly added dropwise, 30 Minute addition is completed. After dropping, Heated to 55 , Reaction for 7 hours, The reaction is completely over. filter, Remove insolubles, The filtrate was poured into 700mL of water, Extraction with ethyl acetate, The ethyl acetate layer was collected, dry, filter, The filtrate is concentrated. To the oily substance obtained after the concentration was added 200 mL of ethanol, Stirring, A white solid precipitation, Collect the solid, Washed with 50mL cyclohexane beating, 45.0 g of product was obtained, Two-step total yield of 80.6% The purity of the product was 98% by HPLC.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.80841-78-7, you can also check out more blogs about80841-78-7
