Acalabrutinib (ACP-196) 是一种具有口服活性，不可逆的，高度选择性的第二代 BTK 抑制剂。Acalabrutinib 与 BTK 的 ATP 结合口袋中的 Cys481 共价结合。Acalabrutinib 在慢性淋巴细胞性白血病 (CLL) 小鼠模型中显示出强大的靶向作用和功效。

Acalabrutinib (ACP-196) is an orally active, irreversible, and highly selective second-generation BTK inhibitor. Acalabrutinib binds covalently to Cys481 in the ATP-binding pocket of BTK. Acalabrutinib demonstrates potent on-target effects and efficacy in mouse models of chronic lymphocytic leukemia (CLL).

Solid

IC50: 3 nM (BTK in CD69 B cell)

Acalabrutinib (ACP-196) inhibits tyrosine phosphorylation of downstream targets of ERK, IKB, and AKT, in the in vitro signaling assay on primary human CLL cells. In the human CLL NSG xenograft model, Acalabrutinib demonstrates on-target effects including decreased phosphorylation of PLCγ2, ERK and significant inhibition of CLL cell proliferation.
Acalabrutinib inhibits purified BTK with an IC50 of 3 nM and an EC50 of 8 nM in a human whole-blood CD69 B cell activation assay. Acalabrutinib has improved target specificity over ibrutinib with 323-, 94-, 19-, and 9-fold selectivity over the other TEC kinase family members (ITK, TXK, BMX, and TEC , respectively) and no activity against EGFR.
has not independently confirmed the accuracy of these methods. They are for reference only.

Acalabrutinib (100 mg twice per day) assessed for thrombus formation at injured arterioles of the mice, exhibits more selective for inhibiting BTK and has virtually no inhibition of platelet activity. has not independently confirmed the accuracy of these methods. They are for reference only.

Room temperature in continental US; may vary elsewhere.
