Biological Activity

Description

Features

Dual Bcr-Abl/Lyn inhibitor.

Targets

Abl ^[1] (Cell-free assay)	Lyn ^[1] (Cell-free assay)
5.8 nM	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. Bafetinib 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, Bafetinib 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, Bafetinib induces both caspase-mediated and caspase-independent cell death by blocking the phosphorylation of Bcr-Abl. ^[2]

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, Bafetinib 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 Bafetinib (60 mg/kg) and cyclosporine A (CsA) (50 mg/kg) leads to more significant inhibition of leukemia growth in the brain than either Bafetinib or CsA alone. ^[3]

Protocol

Kinase Assay:^[1]	- Collapse 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 NS-187 against 79 tyrosine kinases are tested with KinaseProfiler.
Cell Research:^[1]	- Collapse Cell lines: K562, BaF3/wt, BaF3/E255K, and BaF3/T315I cells Concentrations: 0-10 μM Incubation Time: 72 hours Method: K562, BaF3/wt, BaF3/E255K, and BaF3/T315I cells are plated at 1 × 10³ in 96-well plates, whereas KU812 and U937 cells are plated at 5 × 10³ in 96-well plates. Cells are incubated with serial dilutions of Bafetinib for 3 days. Cell proliferation is measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide; Nacalai Tesque) assay, and the 50% inhibitory concentration (IC50) values are calculated by fitting the data to a logistic curve. (Only for Reference)
Animal Research:^[1]	- Collapse Animal Models: KU812 xenograft is established by subcutaneous injection of KU812 cells into the right flank of Balb/c-nu/nu female mice. Dosages: ≤20 mg/kg/day Administration: Administered via p.o. (Only for Reference)

Bio Calculators

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Frequently Asked Questions

Question 1:
Can you suggest the route of in vivo administration for S1369?
Answer:
S1369 in 0.5% methylcellulose+0.2% Tween 80 at 30mg/ml is a suspension, and it is fine for oral gavage. If you dissolved the 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.
