Metabolite Identification
Common NameN,O-Didesmethyltramadol
DescriptionN,O-Didesmethyltramadol, also known as M5, belongs to the class of organic compounds known as cyclohexylphenols. Cyclohexylphenols are compounds containing a cyclohexane lined to a phenol group. N,O-Didesmethyltramadol is a very strong basic compound (based on its pKa). Within humans, N,O-didesmethyltramadol participates in a number of enzymatic reactions. In particular, N,O-didesmethyltramadol and formaldehyde can be biosynthesized from N-desmethyltramadol; which is catalyzed by the enzyme cytochrome P450 2D6. In addition, N,O-didesmethyltramadol and formaldehyde can be biosynthesized from O-desmethyltramadol through its interaction with the enzyme cytochrome P450 2D6. N,O-Didesmethyltramadol is a metabolite of tramadol. The drug has a wide range of applications, including treatment of rheumatoid arthritis, restless legs syndrome, and fibromyalgia. In humans, N,O-didesmethyltramadol is involved in tramadol metabolism pathway. Tramadol hydrochloride (trademarked as Conzip, Ryzolt, Ultracet, Ultram in the USA; Ralivia and Zytram XL in Canada) is a centrally-acting synthetic analgesic used to treat moderate to moderately-severe pain. It was launched and marketed as Tramal by the German pharmaceutical company Grnenthal GmbH in 1977 (Wikipedia).
