UNC9994 hydrochloride
Based on 2 publication(s) in Google Scholar
UNC9994 hydrochloride is a functionally selective, β-arrestin–biased dopamine D2 receptor (D2R) agonist that selectively activates β-arrestin recruitment and signaling. UNC9994 hydrochloride shows a binding affinity with a Ki of 79 nM for D2R. UNC9994 hydrochloride is also an antagonist of Gi-regulated cAMP production and partial agonist for D2R/β-arrestin-2 interactions. UNC9994 hydrochloride shows antipsychotic-like activity.

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 (5.46 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.5 mg/mL.
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.
