Biological Activity
IC50: 0.15 μM (HeLa cell)
RA190 covalently binds to cysteine 88 of ubiquitin receptor RPN13 in the 19S regulatory particle and inhibits proteasome function, triggering rapid accumulation of polyubiquitinated proteins. Multiple myeloma (MM) lines, even those resistant to bortezomib, are sensitive to RA190 via endoplasmic reticulum stress-related apoptosis. RA190 stabilizes targets of human papillomavirus (HPV) E6 oncoprotein, and preferentially kills HPV-transformed cells[1].

Solvent & Solubility
DMSO : ≥ 100 mg/mL (167.57 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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: ≥ 2.38 mg/mL (3.99 mM); Clear solution
This protocol yields a clear solution of ≥ 2.38 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (23.8 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.

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
RA190 is dissolved in DMSO and diluted with cell culture medium. HeLa cells are treated with RA190 (0.2, 0.4, 0.6, 0.8, 1, 2, 3, 4, 5 μM) for 48 hr. Cell viability is assayed using commerical kit[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice: Mice are divided into two groups and treated daily i.p. with RA190 (10 mg/kg) or vehicle, and imaged again on day 7 and day 14. NOG mice (5 per group) are inoculated with 1X106 NCI-H929-GFP-Luc cells i.v., and after 4 weeks, mice are imaged for their luciferase activity and divided into two groups. Mice are treated i.p. with RA190 (20 mg/kg) or vehicle, and imaged again at the end of the treatment for their luciferase activity[1].
