T May et al.
Neuroscience letters, 275(2), 109-112 (1999-11-24)
Rats, for 8 weeks consuming the mu-opioid agonist etonitazene (forced and free choice conditions yielding high and low drug-consumers), were sacrificed after 2 days or 6 weeks lasting drug deprivation. Binding characteristics of membranes from the parieto-occipital cortex of these
Lionel Moulédous et al.
FEBS letters, 589(18), 2401-2408 (2015-08-01)
Many in vitro data have shown that the efficacy of several opioid drugs is correlated with differential mu-opioid (MOP) receptor phosphorylation. Label-free semiquantitative on-line nanoflow liquid chromatography-tandem mass spectrometry (nanoLC-MS/MS) analyses were performed to compare the endogenous MOP receptor phosphorylation
T P Piepponen et al.
Pharmacology, biochemistry, and behavior, 63(2), 245-252 (1999-06-17)
The role of mu1-opioid receptors in the acceleration of cerebral dopaminergic transmission induced by morphine and the putative mu1-opioid agonist, etonitazene, was studied in rats by measuring the tissue levels of dopamine (DA) and its metabolites 3,4-dihydroxyphenylacetic acid (DOPAC) and
G Zernig et al.
Life sciences, 57(23), 2113-2125 (1995-01-01)
In order to quantitate the extent to which opioid agonist potencies obtained in behavioral assays are determined by the apparent in vivo affinity and efficacy of the agonist, the antinociceptive effects of the mu opioid agonists morphine, fentanyl, etonitazene, and
