HIDE SMILES / InChI
O-Desmethyl tramadol (O-Desmethyltramadol, O-DSMT) is a metabolite of tramadol. O-Desmethyltramadol is an opioid analgesic and the main active metabolite of tramadol. (+)-O-Desmethyltramadol is the most important metabolite of tramadol produced in the liver after tramadol is consumed. This metabolite is considerably more potent as a μ-opioid agonist than the parent compound. O-desmethyl tramadol, inhibits 5-hydroxytryptamine type 2C receptors expressed in xenopus oocytes. O-desmethyl tramadol inhibits functions of M(1) receptors but has little effect on those of M(3) receptors. O-desmethyl tramadol has been widely used clinically and has analgesic activity.

Curator's Comment: The administration of 10 mg/kg (+)-O-desmethyl tramadol in a 10-min i.v. infusion significantly altered pCO(2), pO(2), and pH values in comparison with baseline and lower-dose groups. However, 2 mg/kg administered in a 10-min i.v. infusion was enough to achieve 100% antinociception without respiratory depression in rats. https://www.ncbi.nlm.nih.gov/pubmed/10773040

Route of Administration: Oral
O-desmethyl tramadol (0.1-100 uM) inhibited acetylcholine (ACh)-induced currents in oocytes expressing the M(1) receptors (half-maximal inhibitory concentration [IC(50)] = 2 +/- 0.6 uM), whereas it did not suppress ACh-induced currents in oocytes expressing the M(3) receptor. O-desmethyl tramadol inhibited the specific binding of [(3)H]quinuclidinyl benzilate ([(3)H]QNB) to the oocytes expressed M(1) receptors (IC(50) = 10.1 +/- 0.1 uM), whereas it did not suppress the specific binding of [(3)H]QNB to the oocytes expressed M(3) receptors.
