Asciminib (ABL001) 是一种有效和选择性的变构 BCR-ABL1 抑制剂，抑制 Ba/F3 细胞生长的 IC₅₀ 值为 0.25 nM。

Asciminib (ABL001) is a potent and selective allosteric BCR-ABL1 inhibitor, which inhibits Ba/F3 cells grown with an IC 50 of 0.25 nM.

Asciminib binds to the myristoyl pocket of ABL1 and induces the formation of an inactive kinase conformation. NMR and biophysical studies confirm that asciminib binds potently (dissociation constant=0.5-0.8nM) and selectively to the myristoyl pocket of ABL1 and induces the inactive C-terminal helix conformation. Asciminib binding mimics the structural consequences of myristate binding to the N terminus of ABL1. Consistent with this binding site, asciminib exhibits the same non-ATP-competitive biochemical kinetics as the BCR–ABL inhibitor GNF-2 but with approximately 100-fold greater potency. Asciminib 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 has an anti-proliferative with IC50

Asciminib is undergoing clinical development testing in patients with CML and Philadelphia chromosome-positive acute lymphoblastic leukaemia. Single doses of 7.5, 15 and 30 mg/kg ABL001, administered to mice bearing KCL- 22 xenografts, inhibits pSTAT5 (Tyr694), which return to baseline at 10, 12 and 16-20h 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. Similarly, in xenografts derived from patients, treatment with 7.5 and 30 mg/kg asciminib leads to regressions that are maintained during dosing. has not independently confirmed the accuracy of these methods. They are for reference only.
