GR103545 fumarate
GR103545 fumarate is a κ opioid receptor (KOR) selective PET radiotracer and functional agonist with blood-brain barrier permeability and comparable peripheral and central antinociceptive efficacy, with an IC50 of 0.02 nM for KOR agonistic activity. GR103545 fumarate selectively binds to KORs in the brain. GR103545 fumarate induces antinociceptive effects. GR103545 fumarate can be used in research related to neurological disorders such as depression and Alzheimer's disease.

κ Opioid Receptor/KOR 0.02 nM (IC50) |
体内実験
GR103545 (compound 2) (in vitro rabbit vas deferens tissue) fumarate acts as potent competitive kappa opioid receptor (KOR) agonist with IC50 = 0.02 nM and Log D = 3.14; its s.c./i.c.v. antinociceptive potency ratio is 1.5, showing strong blood-brain barrier penetration[2].
11C-GR103545 (i.v.; bolus injection) fumarate exhibits specific, KOR-selective binding in healthy rhesus monkey brain with high BPND values but slow tissue kinetics that delay equilibrium[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.71 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.71 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
