Solvent & Solubility
DMSO : 20.75 mg/mL (45.25 mM; Need ultrasonic and warming; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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: ≥ 1.67 mg/mL (3.64 mM); Clear solution
This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Radioligand binding studies are performed at MDS Pharma Services. Mean percentage inhibition of specific binding or activity is shown for each assay tested, and in selected assays (for BIX 02565) when inhibition of adrenergic binding generally exceeded 50%, an IC50 is determined by a nonlinear least-squares regression analysis. In brief, human RSK2 protein is used to measure kinase activity utilizing Kinase GloPlus that uses a luciferin-luciferase based detection reagent to quantify residual ATP. The relative light unit signal is measured on an LJL Analyst in luminescence mode using 384 aperture; relative light unit signals are converted to percentage of control; the IC50 is fitted to a standard four-parameter logistic equation[1].

Rats[1]
Mean arterial pressure is assessed in conscious, freely moving male Sprague-Dawley rats (n=6/group) instrumented with telemetry transmitters. BIX 02565 (30, 100, and 300 mg/kg p.o. QD) is administered as a solution (10 mL/kg) in a 20% hydroxy-propyl-β-cyclodextran vehicle. Mean arterial pressure is reported from 2 h before (baseline) and 90 h after the first dose; compound is administered at 0, 24, 48, and 72 h. A blood sample is collected from satellite rats (n=3/group) at 1-h after dose (Tmax) on days 1 and 4 for analysis of plasma drug concentrations by mass spectrometry.
