M6g morphine
WebMorphine is mainly metabolised by glucuronidation in the liver with the enzyme primarily responsible being UGT2B7.2 This results in two metabolites morphine-3-glucuronide and morphine-6-glucuronide (M6G) both of which are excreted in the urine.2 Although there has been a traditionally held view that this process is less susceptible to ...

Web10 mai 2005 · In humans, morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G) are formed in a reaction mainly catalyzed by UDP glucuronosyl transferase 2B7 (UGT2B7) ( 6 ). The pharmacological effects of M3G and M6G differ profoundly. M3G has no analgesic properties and is even thought to antagonize some of the effects of … Web1 sept. 2003 · These data suggest that M6G formation may be used as a selective probe for UGT2B7 activity, and morphine glucuronidation by UGT2B7 appears to involve the simultaneous binding of two substrate molecules, highlighting the need for careful analysis of morphine glucuronidation kinetics in vitro.
