描述：

DCC-2036 (Rebastinib)是一种Bcr-Abl抑制剂，作用于Abl1(WT)和Abl1(T315I)，IC50分别为0.8 nM和4 nM，也抑制SRC， LYN， FGR， HCK， KDR， FLT3，和Tie-2，对c-Kit具有低的抑制活性。DCC-2036有效抑制纯化的未磷酸化(u-ABL1^native)和磷酸化 (p-ABL1^native) ABL1, 未磷酸化和磷酸化突变型ABL1^T315I, 及激活环突变ABL1^H396P，这种作用为非ATP竞争性的，IC50分别为0.8 nM, 2 nM, 1.4 nM, 5 nM, 和 4 nM。而且, DCC-2036也抑制SRC家族激酶SRC, LYN, FGR, 和 HCK, 和受体 TKs KDR, FLT3, 和TIE2，IC50分别为34 nM, 29 nM, 38 nM, 40 nM, 4 nM, 2 nM 和6 nM。DCC-2036作用于表达野生型或突变型BCR-ABL1的Ba/F3细胞，具有抗增殖活性，IC50为 2 nM到150 nM。

溶解性：Ethanol ：13 mg/mL (23.5 mM) DMSO ：103 mg/mL (186.1 mM)

体外研究：

DCC-2036 shows the potent inhibitory activities against purified native Abl1 in unphosphorylated (u-Abl1native) and phosphorylated (p-Abl1native) forms, unphosphorylated and phosphorylated gatekeeper mutant Abl1T315I, and the activation loop mutant Abl1H396P in a non-ATP-competitive manner with IC50 of 0.8 nM, 2 nM, 1.4 nM, 5 nM, and 4 nM, respectively. Moreover, DCC-2036 also inhibits the Src family kinases Src, LYN, FGR, and HCK, and the receptor TKs KDR, FLT3, and TIE2 with IC50 of 34 nM, 29 nM, 38 nM, 40 nM, 4 nM, 2 nM and 6 nM, respectively. DCC-2036 shows the anti-proliferative activities against Ba/F3 cells expressing native or mutant Bcr-Abl1 with IC50 ranging from 2 nM to 150 nM. In addition, DCC-2036 also inhibits proliferation of the Ph+ cell line K562 (IC50 5.5 nM), and induces apoptosis in both Bcr-Abl1-expressing Ba/F3 and K562 cells potently. A recent study shows that DCC-2036 shows the selectivity for growth inhibition of Bcr-Abl-positive cells by its marked inhibition of CML cell lines compared to non-CML leukemia lines.

体内研究：In a mouse allograft model bearing Ba/F3-Bcr-Abl1T315I leukemia cells, DCC-2036 treatment by oral gavage at 100 mg/kg once daily effectively inhibits Bcr-Abl1 signaling and significantly prolongs mouse survival.
