RBC8
Based on 1 publication(s) in Google Scholar
RBC8 is a selective and allosteric RALA and RALB inhibitor. RBC8 stabilizes the inactive GDP-bound state of Ral, preventing its activation. RBC8 promotes the phosphorylation of proteins related to the MAPK/JNK pathway. RBC8 has the activity of inhibiting tumor cell proliferation, migration and invasion. RBC8 is used in the study of various cancers such as lung cancer, gastric cancer, and multiple myeloma.

Activité biologique
RBC8 (10-20 μM; 3-72 h) can reduce the survival rate of myeloma cells AMO-1 and INA-6 and the level of RAL-GTP in sensitive INA-6 cells[1]. RBC8 (20 μM; 3 days of treatment) inhibits the colony formation of lung cancer cells H2122 and H358 in soft agar with IC50 of 3.5 μM and 3.4 μM, respectively[2]. RBC8 (20-40 μM) significantly inhibits the growth, migration and invasion of gastric cancer cell lines SGC-7901 and MGC-803[3].

Solvant et solubilité
DMSO : ≥ 40 mg/mL (94.24 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, 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: ≥ 2.5 mg/mL (5.89 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 (5.89 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
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.
