Metabolite Identification
Common NameDihydrocurcumin
DescriptionDihydrocurcumin is a flavonoid, specifically a reductive metabolite of curcumin, which is derived from the rhizome of Curcuma longa. Its chemical structure features a diketone moiety that is reduced at one of the carbonyl groups, resulting in a more saturated compound compared to curcumin. Dihydrocurcumin is primarily produced in the colon through the action of intestinal microbiota, which metabolizes curcumin into several derivatives, including tetrahydrocurcumin (PMID:40362738 ). The enzyme responsible for this conversion, identified as NADPH-dependent curcumin/dihydrocurcumin reductase (CurA), was isolated from Escherichia coli found in human feces (PMID:39122010 ). This compound has been shown to exhibit antioxidant and anti-inflammatory properties, with studies indicating its inhibitory potency against human and rat 17β-HSD1 (PMID:38785078 ). Additionally, molecular docking studies have demonstrated its superior binding affinity to MAPK2 compared to other compounds (PMID:38758988 ). Despite its potential, dihydrocurcumin's bioavailability is limited, and challenges in synthesis hinder its accessibility (PMID:37664191 ). Overall, dihydrocurcumin is an important compound in the context of curcumin metabolism and its biological effects.
