|Description||AZ 960 is a novel ATP competitive JAK2 inhibitor with IC50 and Ki of <3 nM and 0.45 nM, 3-fold selectivity of AZ960 for JAK2 over JAK3. AZ 960 induces apoptosis and growth arrest.|
AZ960 also inhibits many kinases less than 50% at a concentration of 0.1 μM such as JAK3 (IC50=9 nM), TrkA, Aurora, and ARK5. In cells, AZ 960 inhibits the phosphorylation of STAT5 in TEL-JAK2 cells with an average IC50 of 15 nM and exhibits 15-30 -fold sensitivity for TEL-JAK2-driven STAT5 phosphorylation compared with cell lines driven by other JAK kinase family members (TEL-JAK1, -JAK3, and -TYK2). AZ 960 shows potent activity in inhibiting the proliferation of the TEL-JAK2, -JAK1, -JAK3, and -Tyk2 cell lines with GI50 values of 25 nM, 230 nM, 279 nM, and 214 nM, respectively. Moreover, AZ 960 also potently inhibits SET-2 cell proliferation with an average GI50 of 33 nM by reducing both STAT3 and STAT5 phosphorylation levels.  AZ 960 causes growth arrest and apoptosis of human T-cell lymphotropic virus type 1, HTLV-1pe 1, HTLV-1LV-1osis of human T-cSET-2 cell proliferation witBcl-xL by small interfering RNA potentiates anti-proliferative effects of AZ 960 in MT-1 cells.  A recent study shows that AZ 960 leads to significant inhibition of the clonogenic growth and induction of apoptosis of freshly isolated AML cells from patients. 
Enzyme Biochemical Assay and Kinase Profiling:Inhibition studies of AZ 960 are performed using a recombinant JAK2 kinase (amino acids 808–1132) at a peptide (Tyk2 peptide) concentration of 100 nM and an ATP concentration of 15 μM. Concentrations of AZ 960 ranging from 0.003 μM to 30 μM are used. The mode of inhibition and inhibition constant (Ki) of AZ960 against JAK2 kinase are further evaluated by inhibition kinetics. Specifically, a series of JAK2-catalyzed reactions are set up in HEPES buffer (75 mM, pH 7.3) with a fixed concentration of peptide (FL-Ahx-IPTSPITTTYFFFKKK-COOH), and varied concentrations of ATP and AZ 960. The progress of each reaction is subsequently monitored by the Caliper LC3000 system, and the initial velocity of each reaction is extracted from the corresponding reaction time course. To define the mode of inhibition, initial velocities are plotted against corresponding ATP concentrations using Lineweaver-Burk plots and the characteristic convergence of the lines on the y axis demonstrates the competitiveness of AZ 960 to ATP. Initial inspection of Ki using the Michealis-Menten equation revealed that AZ960 is a tight-binding inhibitor of JAK2. AZ960 is profiled against 83 kinases at three inhibitor concentrations (0.01 μM, 0.10 μM, and 1.0 μM).

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).
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.
