Mechanism of Action

Features	Dual Bcr-Abl/Lyn inhibitor.
Targets/IC₅₀/Ki	Abl ^[1] (Cell-free assay) 5.8 nM Lyn ^[1] (Cell-free assay) 19 nM
In vitro	Bafetinib blocks WT Bcr-Abl autophosphorylation and its downstream kinase activity with IC50 of 11 nM and 22 nM in K562 and 293T cells, respectively. This compound suppresses the growth of the Bcr-Abl-positive cell lines including K562, KU812, and BaF3/wt cells potently without effects on the proliferation of the Bcr-Abl-negative U937 cell line. Moreover, it exhibits a dose-dependent antiproliferative effect against Bcr-Abl point mutant cell lines, such as BaF3/E255K cells. ^[1] In Bcr-Abl+ leukemia cell lines, this chemical induces both caspase-mediated and caspase-independent cell death by blocking the phosphorylation of Bcr-Abl. ^[2]
Kinase Assay	Kinase assay
Kinase Assay	Bcr-Abl kinase assays are performed in 25 μL of reaction mixture containing 250 μM peptide substrate, 740 Bq/μL [γ-³³P]ATP, and 20 μM cold adenosine triphosphate (ATP) by using the SignaTECT protein tyrosine kinase assay system. Each Bcr-Abl kinase is used at a concentration of 10 nM. Kinase assays for Abl, Src, and Lyn are carried out with an enzyme-linked immunosorbent assay (ELISA) kit. The inhibitory effects of this compound against 79 tyrosine kinases are tested with KinaseProfiler.
In vivo	In Bcr-Abl–positive KU812 mouse model, Bafetinib (0.2 mg/kg/day) significantly inhibits tumor growth, and completely inhibits tumor growth without adverse effects at 20 mg/kg/day. For Balb/c mice, this compound shows maximal tolerated dose of 200 mg/kg/d and bioavailability value (BA) of 32%. ^[1] In a Central nervous system (CNS) leukemia model bearing Ba/F3/wt bcr-ablGFP, Ba/F3/Q252H, or Ba/F3/M351T cells, combination treatment of this chemical (60 mg/kg) and CsA (50 mg/kg) leads to more significant inhibition of leukemia growth in the brain than either this compound or CsA alone. ^[3]

Frequently Asked Questions

Question 1:
Can you suggest the route of in vivo administration for it?

Answer:
It is fine for oral gavage when suspended in 0.5% methylcellulose+0.2% Tween 80 at 30mg/ml. If you dissolved this compound in 0.5% methyl cellulose and got a suspension, it is fine. And 0.2% Tween 80 can help the suspension dissolving more homogeneous.
