In Vitro

Rebastinib potently (IC₅₀ 0.82 nM) inhibits u-ABL1^native, which is thought to exist predominantly in the inactive type II conformation. In addition, Rebastinib also strongly inhibits p-ABL1^native (IC₅₀ 2 nM), which more readily adopts an active, Type I conformation^[1].
Rebastinib potently inhibits both u-ABL1^T315I (IC₅₀ 5 nM) and p-ABL1^T315I (IC₅₀ 4 nM), both of which exist predominately in the Type I conformation due to stabilization of an activating hydrophobic spine by the T315I mutation^[1].
In addition to ABL1, Rebastinib also inhibits the SRC family kinases LYN, SRC, FGR, and HCK, and PDGFRα, and PDGFRβ with IC₅₀ of 29±1, 34±6, 38±1, 40±1, 70±10 and 113±10 nM, respectively. Notably, Rebastinib spared c-KIT (IC₅₀ 481 nM)^[1].
Rebastinib effectively inhibits the proliferation of Ba/F3 cells expressing native BCR-ABL1^native (IC₅₀ 5.4 nM). Rebastinib also inhibits proliferation of the Ph⁺ cell line K562 (IC₅₀ 5.5 nM)^[1].
Rebastinib also inhibits proliferation of several common TKI-resistant mutants of BCR-ABL1, including G250E, Q252H, Y235F, E255K, V299L, F317L, and M351T, at IC₅₀s ranging from 6-150 nM. Rebastinib effectively inhibits autophosphorylation of BCR-ABL1^native (IC₅₀ 29 nM) and BCR-ABL1^T315I (IC₅₀ 18 nM), as well as the phosphorylation of STAT5 in both cell lines (IC₅₀ 28 nM and 13 nM, respectively)^[1].

* 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.

Protocol 1

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (3.76 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
