Carbenoxolone-d₄ 

Carbenoxolone-d₄ is deuterium labeled Carbenoxolone. Carbenoxolone, a semi-synthetic derivative of glycyrrhetinic acid, has previously been used for the management of dyspepsia and peptic ulcer because of its anti-inflammatory properties[3]. Carbenoxolone, a general hemichannel and gap junction inhibitor, has the therapeutic potential of carbenoxolone in the research of chronic liver disease[2]. Carbenoxolone is a suitable candidate for the inhibition of Aβ42 aggregation and the therapeutic potential of Cbx against AD[1]. Carbenoxolone is small molecule Pannexin1 (Panx1,is an ATP release channel) inhibitor, attenuate Panx1 channel activity through modulation of the first extracellular loop[4].Carbenoxolone is an 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) inhibitor that converts inactive glucocorticoid into an active form. Carbenoxolone has antiviral activity against DENV infection targeting the virus itself[6].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
