Associations of morphine with other chemical compounds

  • DeltaFosB overexpression in the NAc increased the sensitivity of the mice to the rewarding effects of morphine and led to exacerbated physical dependence, but also reduced their sensitivity to the analgesic effects of morphine and led to faster development of analgesic tolerance [1].
  • We show that the ability of morphine withdrawal to stimulate phosphorylation at this seryl residue is reduced by SL327, an inhibitor of ERK(1/2) activation [2].
  • Receptor binding studies and FRET measurements demonstrated that several (R)-configurated morphine precursors such as (R)-reticuline, salutaridine, salutaridinol, thebaine, and codeine were partial MOR agonists [3].
  • Antinociception induced by s.c., intrathecal, or intracerebroventricular injection of the morphine metabolite morphine-6-glucuronide (M-6-G) was significantly decreased by sciatic nerve ligation [4].
