产品活性:Asciminib (ABL001) hydrochloride is a potent and selective allosteric BCR-ABL1 inhibitor, which inhibits Ba/F3 cells grown with an IC50 of 0.25 nM.
研究领域:Protein Tyrosine Kinase/RTK
作用靶点:Bcr-Abl
In Vitro: Asciminib (ABL001) hydrochloride binds to the myristoyl pocket of ABL1 and induces the formation of an inactive kinase conformation.
Asciminib hydrochloride binds potently (dissociation constant=0.5-0.8 nM) and selectively to the myristoyl pocket of ABL1 and induces the inactive C-terminal helix conformation. Asciminib hydrochloride exhibits the same non-ATP-competitive biochemical kinetics as the BCR–ABL inhibitor GNF-2 but with approximately 100-fold greater potency.
Asciminib hydrochloride lacks activity against more than 60 kinases, including SRC, and is similarly inactive against G-protein-coupled receptors, ion channels, nuclear receptors and transporters.
In BCR–ABL1-transformed Ba/F3 cells grown without IL-3, Asciminib hydrochloride has an anti-proliferative with IC50 value of 0.25 nM. In the CML blast-phase cell line KCL-22, Asciminib hydrochloride inhibits phosphorylation of both STAT5 (Tyr694; pSTAT5) and BCR–ABL1 (Tyr245; pBCR–ABL1) after 1 h using concentrations that correlate with those required for inhibition of cell proliferation.
Asciminib hydrochloride is selectively active against all BCR–ABL1 lines (IC50 value of 1–20 nM), irrespective of the presence of either the p210 or the p190 BCR–ABL1 isoform.
In Vivo: Single doses of 7.5, 15 and 30 mg/kg Asciminib, administered to mice bearing KCL- 22 xenografts, inhibits pSTAT5 (Tyr694), which return to baseline at 10, 12 and 16-20 h after administration of the dose, respectively. In mice implanted with KCL-22 tumors, the minimum dose of Asciminib required for complete regression is 7.5 mg/kg twice a day (BID) or 30 mg/kg once a day (QD), and is tolerated at doses up to 250 mg/kg BID.
