Name: Acalabrutinib (ACP-196)
Brand: Selleck Chemicals
SKU: S8116
Rating: 5 (48 reviews)

Catalog No.S8116 Purity:99.89%

Acalabrutinib (ACP-196) is a selective second-generation Bruton's tyrosine kinase (BTK) inhibitor with an IC50 of 3 nM, which prevents the activation of the B-cell antigen receptor (BCR) signaling pathway. ACP-196 has improved target specificity 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 vitro
In vitro	In the in vitro signaling assay on primary human CLL cells, acalabrutinib inhibits tyrosine phosphorylation of downstream targets of ERK, IKB, and AKT. Acalabrutinib demonstrates higher selectivity for BTK with IC50 determinations on nine kinases with a cysteine residue in the same position as BTK. acalabrutinib has no effect on EGFR phosphorylation on tyrosine residues Y1068 and Y1173.
