Description

Takinib (EDHS-206) is a potent and selective TAK1 inhibitor with an IC50 of 9.5 nM, more than 1.5 log more potent than the second and third ranked targets, IRAK4 (120 nM) and IRAK1 (390 nM), respectively. Takinib induces apoptosis.

9.5 nM	120 nM	390 nM

In vitro

Takinib is an inhibitor of autophosphorylated and non-phosphorylated TAK1 that binds within the ATP-binding pocket and inhibits by slowing down the rate-limiting step of TAK1 activation. At 10 μM, Takinib shows significant inhibitory activity (<10% enzyme activity after exposure) on six serine/threonine kinases, including TAK1, IRAK4, IRAK1, GCK, CLK2, and MINK1. TAK1/MAP3K7 is most potently inhibited with a half maximal inhibitory concentration (IC50) value of 9.5 nM. In cell models of rheumatoid arthritis and metastatic breast cancer, Takinib treatment results in TNF-a-dependent induction of apoptosis due to inhibition of TAK1 as a key switch between survival and cell death. Takinib does not inhibit any of the MAP2Ks or MAP3Ks family members, i.e., MKK6/MAP2K6, MEKK1/ MAP3K1, MKK1/MAP2K1. Takinib also shows no efficacy toward the TAK1-closely related MAP3K5/ASK1. Takinib potently and selectively targets TAK1 and induces apoptosis in TNF-a-stimulated breast cancer and RA in vitro models^[1].

^[1]

- Collapse

Cell lines: MDA-MB-231 cells
Concentrations: --
Incubation Time: 24 h
Method:
MDA-MB-231 cells (1,000 cells/well) are seeded in a 96-well plate with 10% FBS, 5% Pen/Strep, 4g/l glucose DMEM medium. After 24h, cells are serum starved with 1% FBS, 5% Pen/Strep, 4g/l glucose DMEM medium for 4h. Cells are treated with titrations of Takinib in the presence or absence of 30 ng/mL TNFa. Plates at 0h and 24h following treatment were frozen at -80℃ after removal of media. After 24h, 100 μl ddH2O is added to each well and plates are refrozen. 1 μl from Hoechst stock [1 mg/ml in 1:4 DMSO/H2O] is dissolved in 1 ml of TNE buffer (10mM Tris, 2M NaCl, 1 mM Na2EDTA) and 100 μl of this solution is added to each well. The fluorescence is determined at 355/460 nm.

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).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

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.
