RA306
Based on 1 Customer Validation
RA306 is an orally active CaMKIIδ/γ inhibitor with IC50 values of 15, 25, 61, and 420 nM against CaMKIIδ, γ, α, and β isoforms, respectively. RA306 reduces the serine/threonine phosphorylation level of PEAK1, inhibits PEAK1-mediated cancer cell migration and invasion, and attenuates the growth and metastasis of cancer xenografts. RA306 can be used in research related to triple-negative breast cancer and dilated cardiomyopathy.

RA306 (1 μM; 24 h) significantly inhibits serine/threonine phosphorylation of PEAK1 in MDA-MB-231_EcoR cells stably expressing Flag-tagged PEAK1[1].
RA306 (120 h) reduces the viability of MDA-MB-231_HM cells in a dose-dependent manner in both high-adhesion and ultra-low-adhesion plates[1].
RA306 blocks PEAK1-mediated migration of MDA-MB-231 and MDA-MB-468 cells in transwell migration assays[1].
RA306 blocks PEAK1-mediated invasion of MDA-MB-231 cells in Matrigel chamber invasion assays[1].

Result:Significantly inhibited serine/threonine phosphorylation of PEAK1, with relative phosphorylation levels reduced compared to untreated controls.
RA306 (30 mg/kg; p.o.; twice daily; 14 days) significantly improves the ejection fraction and cardiac output of α-actin transgenic (TG) mice with dilated cardiomyopathy, via a mechanism of reducing myocardial CaMKII activity by inhibiting PLN threonine-17 phosphorylation[2].
RA306 (30 mg/kg; p.o.; once daily for two months) significantly improves the ejection fraction and cardiac output of α-actin TG mice with advanced dilated cardiomyopathy, and exerts no effect on the detected cardiac remodeling parameters[2].

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 (4.37 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.
