Clear solution
2% DMSO 30% PEG 300 2%Tween80 66%ddH2O
1.5mg/ml Taking the 1 mL working solution as an example, add 20 μL of 75 mg/ml clarified DMSO stock solution to 300 μL of PEG300, mix evenly to clarify it; add 20 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 660 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description 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.
Targets
BTK [1]
(in a human whole-blood CD69 B cell activation assay)
3nM
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. 
In vivo

A similar model is used to compare the duration of Btk inhibition after a single oral dose of 25 mg/kg. ACP-196 inhibits CD86 expression >90% at 3h postdose[3].
