Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1121-89-7, molcular formula is C5H7NO2, introducing its new discovery. Quality Control of: Piperidine-2,6-dione
A series of 2-(2-nitrobenzoyl)cyclohexane-1,3-dione analogues (1 -9) were designed, synthesized, and evaluated for inhibition of 4-hydroxyphenylpyruvate dioxygenase (4-HPPD), a key enzyme involved in the catabolism of tyrosine which catalyzes the conversion of 4-hydroxyphenylpyruvate to homogentisate. The correlations between the results of enzyme inhibition, ferric chloride tests, and the conformational analysis suggested that the tight binding between triketonetype inhibitors and 4-HPPD is likely due to chelation of the enzyme-bound ferric iron with the enol tautomer of 1,3-diketone moiety of the triketones. The presence of a 2-carbonyl group in the triketone is an essential structural feature for potent 4-HPPD inhibition. Modification of the 3-carbonyl group of triketone moiety to other functionality will reduce the overall planarity and thus prevent keto-enol tautomerization, resulting in a decrease or lack of inhibition activity.
One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Quality Control of: Piperidine-2,6-dione, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 1121-89-7
