Piperlongumine, a natural alkaloid from Piper longum L., increases the level of reactive oxygen species (ROS) and selectively kills cancer cells. It is a direct TrxR1 inhibitor with suppressive activity against gastric cancer and a novel inhibitor of CRM1; also an inhibitor of PI3K/Akt/mTOR in human breast cancer cells.

a. Cell growth of ARID1A-wildtype RMG1 cells transfected with ARID1A and non-target siRNA for 24 h and treated with piperlongumine for 72 h. b. Apoptosis of RMG1 cells after transfection and treatment as described in a as measured using annexin-V and PI staining. c. Cell growth of RMG1 cells transfected and treated with 5 μM of piperlongumine as described in a, but in the presence or absence of the antioxidant NAC. Cell growth was measured using the WST-1 assay and quantified relative to DMSO treated non-target control. *P < 0.05; **P < 0.01; ***P < 0.001.

| In vitro |
Piperlongumine is a known ROS inducer which could induce pancreatic cancer cell death in cell culture[1] As a thromboxane A(2) receptor antagonist, Piperlongumine inhibits platelet aggregation. [2] Piperlongumine also promotes autophagy via inhibition of Akt/mTOR signalling and mediates cancer cell death. [3] |

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.
