New Advances in Chemical Research, April 2021. 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.3-Bromocinnoline,which mentioned a new discovery about 78593-33-6. 78593-33-6
(a) 3-(4-Hydroxybenzenesulphonyl)cinnoline A mixture of 2.1 g (0.01 mol) of 3-bromocinnoline, 6.6 g (0.02 mol) of sodium 4-tosyloxybenzenesulphinate and 50 ml of dimethylsulphoxide was stirred and heated at 120 C. for 24 hours. The mixture was poured into water and extracted with dichloroethane. The dichloroethane solution was washed with water, dried on anhydrous sodium sulphate and filtered. The solvent was then evaporated with a rotatory evaporator to provide 2.5 g of an oily residue. The desired product was then isolated by chromatography on a silica column using dichlorethane/methanol 98/2. In this manner, 0.45 g of 3-(4-hydroxybenzenesulphonyl)cinnoline was obtained. Yield: 10.2%
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 3-Bromocinnoline,and how the biochemistry of the body works.78593-33-6
