MPAM-15
MPAM-15 is a blood-brain barrier-penetrant pan-orthosteric allosteric modulator (PAM) of opioid receptors, with ≥16-fold selectivity for μOR over δOR and κOR. MPAM-15 acts as an anti-nociceptive potentiator and analgesic, and its activity is observed in mouse models via both intracerebroventricular and intraperitoneal administration. MPAM-15 is applicable for pain-related research.

MPAM-15 (10 μM) potentiates DAMGO-induced cAMP inhibition in HEK293T cells expressing human μOR, increasing the agonist's pEC50 from 8.8 to 9.9[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
MPAM-15 (15-30 mg/kg; i.p.; single administration) exerts no analgesic effect on its own, but it significantly potentiates the analgesic effect of low-dose morphine and prevents the side effects induced by morphine[1].

Animal Model:C57BL/6J (male and female, 8 to 10 weeks old)[1]
-
Dosage:1.5 μM; 2.5 μM; 5 μM
-
Administration:i.c.v.; single dose
-
Result:Increased response latencies to ~45 s (1.5 μM), ~55 s (2.5 μM), and ~50 s (5 μM) at 10 minutes post-injection.
Increased response latencies to ~35 s (1.5 μM), ~45 s (2.5 μM), and ~40 s (5 μM) at 15 minutes post-injection.\nEnhanced morphine-induced antinociception in a dose-dependent manner, with the 5 μM dose producing the longest and highest analgesic effect.
Increased response latency to ~70 s at 10 minutes post-injection, ~65 s at 15 minutes, and ~45 s at 30 minutes post-injection (5 μM dose).

-
Dosage:15 mg/kg; 30 mg/kg
-
Administration:i.p.; single dose
-
Result:Significantly enhanced the analgesic effect of low-dose morphine (3 and 5 mg/kg), and the combined effect was comparable to that of high-dose morphine (10 mg/kg) used alone.
Did not cause constipation, respiratory depression, or addiction.
