Web20 feb. 2008 · We also show that morphine and M6G at concentrations as low as 10 −10 M are able to evoke specific naloxone-reversible membrane currents, indicating possible autocrine/paracrine regulation in SH-SY5Y cells. Microscopy and proteomic approaches were employed to detect and quantify endogenous morphine in the mouse brain. WebMorphine-3-glucuronide is a metabolite of morphine produced by UGT2B7. [1] It is not active as an opioid agonist, [2] but does have some action as a convulsant, which does not appear to be mediated through opioid receptors, [3] but rather through interaction with glycine and/or GABA receptors.
