Interleukin-6 (IL-6) secretion was inhibited by B7‐H4 silence through JAK2/signal transducer and activator of transcription 3 (STAT3) inactivation. (a) ELISA results showed that, compared with cells pretreated with control shRNA, B7‐H4 silence led to reduction of IL‐6 secretion. However, compared with cells pretreated with control shRNA and FLLL32, IL‐6 secretion in Eca109, TE1, and TE13 esophageal squamous cell carcinoma cells pretreated with B7‐H4 shRNA and FLLL32 was not significantly affected.

|Description||FLLL32 is a potent JAK2/STAT3 inhibitor with IC50 of <5 μM. FLLL32 inhibits the induction of STAT3 phosphorylation by IFNα and IL-6 in breast cancer cells.|
In MDA-MB-231 breast and PANC-1 pancreatic cancer cells, FLLL32 downregulates STAT3 phosphorylation and DNA-binding activity. In MDA-MB-231 cells, FLLL32 inhibit the formation of colonies and cell invasion.  In human multiple myeloma, glioblastoma, liver cancer, and colorectal cancer cell lines, FLLL32 also leads to the inhibition of cell proliferation and the induction of caspase-3 and PARP cleavages. 
|In vivo||In MDA-MB-231 xenografted mice, FLLL32 (50 mg/kg, i.p.) significantly reduces tumor burdens.  In mouse xenografts with OS-33 osteosarcoma cells, FLLL32 (50 mg/kg, i.p.) also inhibits tumor growth by targeting STAT3. |
JAK2 and other human kinase activity assays:JAK2 kinase activity was assessed with the HTScan JAK2 Kinase Assay Kit per manufacturer's protocol. The possible effects of FLLL32 on the other 10 purified human protein kinases were determined by using a Kinase Profiler Assay.
|In vitro||DMSO||92 mg/mL (198.04 mM)|
|Ethanol||25 mg/mL warmed (53.81 mM)|
* 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.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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.
