生物活性

Rebastinib (DCC-2036) is an orally active, non-ATP-competitive Bcr-Abl inhibitor for Abl1 and Abl1 with IC₅₀s of 0.8 nM and 4 nM, respectively. Rebastinib also inhibits SRC, KDR, FLT3, and Tie-2, and has low activity to seen towards c-Kit.

体外研究

Rebastinib potently (IC₅₀ 0.82 nM) inhibits u-ABL1, which is thought to exist predominantly in the inactive type II conformation. In addition, Rebastinib also strongly inhibits p-ABL1 (IC₅₀ 2 nM), which more readily adopts an active, Type I conformation.
Rebastinib potently inhibits both u-ABL1 (IC₅₀ 5 nM) and p-ABL1 (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.
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).
Rebastinib effectively inhibits the proliferation of Ba/F3 cells expressing native BCR-ABL1 (IC₅₀ 5.4 nM). Rebastinib also inhibits proliferation of the Ph cell line K562 (IC₅₀ 5.5 nM).
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 (IC₅₀ 29 nM) and BCR-ABL1 (IC₅₀ 18 nM), as well as the phosphorylation of STAT5 in both cell lines (IC₅₀ 28 nM and 13 nM, respectively).

体内研究

A single dose of Rebastinib (DCC-2036; oral; 100 mg/kg) affords circulating plasma levels that exceeds 12 μM for up to 24 hours, and effectively inhibits BCR-ABL1 signaling for up to 8 hours in Ba/F3-BCR-ABL1 leukemia cells isolated from BM and spleen of tumor-bearing mice.
Treatment of mice bearing Ba/F3-BCR-ABL1 leukemia cells with Rebastinib at 100 mg/kg once daily by oral gavage significantly prolonged their survival, while STI571 at 100 mg/kg twice daily is ineffective.
In this aggressive allograft model, Rebastinib is as effective for treatment of BCR-ABL leukemia as STI571 at 100 mg/kg twice daily in BCR-ABL1 leukemia, and reduces the leukemia cell burden in the spleens of treated mice.
