M119
M119 (NSC 119910) is a Gβγ subunit and PLCβ3 inhibitor with selective activity toward μ-opioid receptor-related pathways. M119 selectively inhibits Gβγ-dependent PLCβ3 activation, reduces inositol phosphate production, and enhances μ-opioid receptor-mediated antinociception. M119 attenuates acute μ-opioid receptor agonist-induced antinociceptive tolerance and physical dependence in mice. M119 can be used for pain-related research.

M119 (10-30 µM; 30 min) concentration-dependently inhibits µ-opioid receptor (hMOR-CHO cell)-mediated inositol phosphate production, with significant inhibition observed at 10 µM and 30 µM[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
M119 (100 nM; intracerebroventricular injection; single administration; given 30 minutes prior to Naloxone treatment) significantly attenuates acute Naloxone (HY-17417A)-induced physical dependence in mice, reducing the withdrawal jumping response triggered by the μ-opioid receptor antagonist by approximately 68%[1].

-
Animal Model:ICR mice (male, 20-30 g)[1]
-
Dosage:100 nM (coadministered with intracerebroventricular agonists); 100 mg/kg (administered immediately before subcutaneous μ-opioid receptor agonist)
-
Administration:i.c.v.; single dose; coadministered with agonists; i.p.; single dose; administered immediately before subcutaneous μ-opioid receptor agonist
-
Result:Produced a 10-fold leftward shift in μ-opioid receptor agonist's antinociceptive dose-response curve.
Produced a sevenfold leftward shift in μ-opioid receptor agonist DAMGO's dose-response curve, with DAMGO's ED50 decreasing from 0.07 nmol to 0.01 nM.
Produced a twofold leftward shift in κ-opioid receptor agonist U50,488's dose-response curve, with U50,488's ED50 decreasing from 37 nmol to 17 nM.
Had no significant effect on antinociception mediated by δ1-selective agonist DPDPE or δ2-selective agonist Deltorphin II.
Produced a fourfold leftward shift in μ-opioid receptor agonist's antinociceptive dose-response curve, with μ-opioid receptor agonist's ED50 decreasing from 5.0 mg/kg to 1.3 mg/kg.
Had no effect on baseline tail-withdrawal latencies.
