Piperlongumine Chemical Structure

Molecular Weight(MW): 317.34

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.

    Oncotarget, 2016, 7(35):56933-56943. Piperlongumine purchased from Selleck.

    MPC cells were treated with the indicated concentrations of PL at 21% and 1% O2 for 24 hours. Total cell lysates were subjected to Western blot with antibodies against cleaved PARP, cleaved caspase 3, and caspase 3. β-tubulin was used as a loading control. A representative image (n=3) is shown.

Biological Activity

Description 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.
reactive oxygen species (ROS) [1] TrxR1 [5] CRM1 [6] PI3K/Akt/mTOR [7]
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]

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.
