Product Information:

Acalabrutinib, also known as ACP-196, is an orally available inhibitor of Bruton’s tyrosine kinase (BTK) with potential antineoplastic activity. Upon administration, ACP-196 inhibits the activity of BTK and prevents the activation of the B-cell antigen receptor (BCR) signaling pathway. This prevents both B-cell activation and BTK-mediated activation of downstream survival pathways. This leads to an inhibition of the growth of malignant B cells that overexpress BTK. BTK, a member of the src-related BTK/Tec family of cytoplasmic tyrosine kinases, is overexpressed in B-cell malignancies; it plays an important role in B lymphocyte development, activation, signaling, proliferation and survival.

In Vitro:

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.

 

In Vivo:

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.
