PZM21 is a novel, potent and selective Gi activator with exceptional selectivity for μ opioid receptor (μOR) and minimal β-arrestin-2 recruitment with an EC50 of 1.8 nM. It's an experimental opioid analgesic that's being researched for pain management. PZM21 is a functionally selective μ-opioid receptor agonist that causes G protein signaling mediated by the μ-opioid receptor. Its potency and efficacy are comparable to those of morphine, but it recruits less β-arrestin 2. PZM21 demonstrated considerably fewer side effects than either morphine or TRV130 in mouse experiments. It also caused less constipation than morphine and very little respiratory depression, even at high dosages. However, PZM21 was marginally less effective as an analgesic than either drug.

PZM21 is a 500-fold weaker δOR agonist, indicating that it is a selective μOR agonist, but it exhibits no discernible κOR or nociceptin receptor agonist activity. In fact, it is an 18 nM κOR antagonist. PZM21's IC50 at hERG ranges from 2 to 4 μM, which is 500–1,000 times less potent than its μOR agonist potency. PZM21 and other μOR agonists appear to mainly rely on the heterotrimeric G protein Gi/o for their signaling, since pertussis toxin neutralizes their effect on cAMP levels and they show no activity in a calcium release assay [1].

| ln Vivo |
PZM21 is a potent Gi activator that has minimal β-arrestin-2 recruitment and remarkable selectivity for μOR. At equivalent analgesic dosages, PZM21 does not cause respiratory depression in mice and is effective for the affective rather than the reflexive aspect of analgesia. In a mouse hotplate test, PZM21 exhibits dose-dependent analgesia; 15 minutes after the highest dose of the drug under test was administered, an 87% maximal possible effect (% MPE) was attained [1]. PZM21 has a long-lasting analgesic effect on CNS mediated-pain responses, but does not cause respiratory depression and constipation, two key side effects of opioid agonists[2].

| Animal Protocol |
Mice: PZM21 dissolves in 0.9% NaCl. PZM21 injections (10 mg/kg, 20 mg/kg, or 40 mg/kg) are given to mice. The analgesic effect of a drug injection is measured 15, 30, 60, 90, and 120 minutes after drug treatment, and is expressed as a percentage of the maximum possible effect (%MPE)[1].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.92 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 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: ≥ 2.5 mg/mL (6.92 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 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

*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.
