WebDespite the importance of LonP1 in health and disease, specific inhibitors of this protease are unknown. Here, we demonstrate that 2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oic acid (CDDO) and its -methyl and -imidazole derivatives reversibly inhibit LonP1 by a noncompetitive mechanism, blocking ATP-hydrolysis and thus proteolysis. WebHYDROLYSIS OF NITRILES Nitriles can hydrolyze in aqueous acid to a carboxylic acid and ammonium ion. In the hydrolysis of the cyano group addition of one mole of water forms an enol of amide (an imidic acid) Nitriles can hydrolyze in the aqueous base to a carboxylic acid anion and an amine.
