IUPAC 名称
3-[(2R,15S,17S)-17-hydroxy-2,15-dimethyl-5-oxotetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadec-6-en-14-yl]-3-oxopropanoic acid
描述
11b,20-dihydroxy-3-oxopregn-4-en-21-oic acid or DHOPA is a major metabolite of corticosterone that is typically elevated in the liver. The in vivo conversion of corticosterone to DHOPA is thought to proceed via the aldehyde intermediate 11b-hydroxy-3,20-dioxopregn-4-en-21-al. Cytochrome P450 3A4 (CYP3A4), is known to convert corticosterone to the gem-diol form of the aldehyde. Because CYP3A4 is highly abundant in the liver, the conversion of corticosterone to its aldehyde presumably occurs readily, and the formation of DHOPA by isomerization of the aldehyde. DHOPA has also been identified as a biomarker that is elevated (50 X) in animals that have been treated with PPARalpha agonists. Peroxisome proliferator-activated receptor alpha (PPARalpha) is a nuclear receptor with manifold effects on intermediary metabolism (PMID: 17550978). [HMDB]
