Cebranopadol (also known as GRT-6005) is a novel, first in class compound with potent agonist activity on ORL-1 (opioid receptor like -1) and the well established mu opioid receptor. Cebranopadol is an analgesic nociceptin/orphanin FQ peptide (NOP) that exhibits high potency and efficacy 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. It is being evaluated in clinical Phase 2 and Phase 3 trials for the treatment of chronic and acute pain. Recent evidence indicates that the combination of opioid and NOP receptor agonism may be a new treatment strategy for cocaine addiction.

With Ki values 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 0.9±0.2 nM, 0.7±0.3 nM, and 2.6±1.4 nM for rat NOP, MOP, and KOP receptor, respectively, cebranopadol binds to opioid receptors with high affinity (subnanomolar to nanomolar range) to nociceptin/orphanin FQ peptide (NOP) and opioid receptors[1].

ln Vivo |
With ED50 values of 0.5-5.6 μg/kg after intravenous and 25.1 μg/kg after oral administration, cebrachanopadol demonstrates 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, and diabetic neuropathy). Cebranopadol is more effective in models of chronic neuropathic pain than acute nociceptive pain when compared to selective MOP receptor agonists. The long half-life of cebranopadol is demonstrated by its prolonged duration of action (up to 7 hours after intravenous 12 μg/kg; >9 hours after oral 55 μg/kg in the rat tail-flick test). Pretreatment with either opioid receptor antagonist naloxone or selective NOP receptor antagonist J-113397 partially reverses the antihypersensitive activity of cebranopadol in the spinal nerve ligation model, suggesting that both opioid receptor agonism and NOP are involved in this activity[1].

Solubility (In Vivo) |
Solubility in Formulation 1: 0.67 mg/mL (1.77 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 6.7 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 0.67 mg/mL (1.77 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 6.7 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 0.67 mg/mL (1.77 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
