Cebranopadol

Research use only, not for human use.

Cebranopadol (GRT-6005, GRT6005) is a potent analgesic nociceptin/orphanin FQ peptide (NOP) and opioid receptor agonist with Ki/EC50 of 0.9/13 nM (human NOP receptor), 0.7/1.2 nM (mu-opioid receptor).

Cebranopadol (GRT-6005, GRT6005) is a potent analgesic nociceptin/orphanin FQ peptide (NOP) and opioid receptor agonist with Ki/EC50 of 0.9/13 nM (human NOP receptor), 0.7/1.2 nM (mu-opioid receptor); exhibits highly potent and efficacious antinociceptive and antihypersensitive effects in several rat models of acute and chronic pain with ED50 values of 0.5-5.6 μg/kg after oral administration, does not disrupt motor coordination and respiration.Pain Phase 3 Clinical(In Vitro):Cebranopadol binds with high affinity (subnanomolar to nanomolar range) to nociceptin/orphanin FQ peptide (NOP) and opioid receptors, with Ki of 1±0.5 nM, 2.4±1.2 nM, and 64±11 nM for rat NOP, mu-opioid peptide (MOP) receptor, and kappa-opioid peptide (KOP) receptor, and with Ki of 0.9±0.2 nM, 0.7±0.3 nM, and 2.6±1.4 nM for Rat NOP, MOP, and KOP receptor.(In Vivo):Cebranopadol exhibits highly potent and efficacious antinociceptive and antihypersensitive effects in several rat models of acute and chronic pain (tail-flick, rheumatoid arthritis, bone cancer, spinal nerve ligation, diabetic neuropathy) with ED50 values of 0.5-5.6 μg/kg after intravenous and 25.1 μg/kg after oral administration. In comparison with selective MOP receptor agonists, cebranopadol is more potent in models of chronic neuropathic than acute nociceptive pain. Cebranopadol’s duration of action is long (up to 7 hours after intravenous 12 μg/kg; >9 hours after oral 55 μg/kg in the rat tail-flick test). The antihypersensitive activity of cebranopadol in the spinal nerve ligation model is partially reversed by pretreatment with the selective NOP receptor antagonist J-113397 or the opioid receptor antagonist naloxone, indicating that both NOP and opioid receptor agonism are involved in this activity.
