Solubility (25°C)* In vitro DMSO 50 mg/mL (201.35 mM)
Ethanol 50 mg/mL (201.35 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.12mg/ml Taking the 1 mL working solution as an example, add 50 μL of 62.4 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* 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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description (-)-Parthenolide, an inhibitor of the Nuclear Factor-κB Pathway, specifically depletes HDAC1 protein without affecting other class I/II HDACs; Also promotes the ubiquitination of MDM2 and activates p53 cellular functions.
Targets
HDAC1 [1] NF-κB [2] MDM2 [3] p53 [3]
In vitro

Parthenolide (PTL), a sesquiterpene lactone purified from the shoots of the feverfew, inhibits ubiquitin-specific peptidase 7 (USP7) activity and deubiquitinate and stabilize β-catenin which the key transcriptional factor of Wnt signaling pathway, suggesting that PTL is an promising anticancer agent targeting aberrant USP7/Wnt signaling.[4]
In vivo

Parthenolide (PN), a P65 inhibitor, significantly increases the tumor volumes in subcutaneous xenograft gastric cancer (GC) mouse model, which can be reversed by gastrin.[5]

Protocol (from reference)

Cell Assay:

[4]
  • Cell lines

    HCT116, SW480, HEK293W cells

  • Concentrations

    2.5, 5.0, 10 μM

  • Incubation Time

    24 h

  • Method

    To confirm PTL as a Wnt signaling inhibitor, HEK293W cells are seeded in 96-well plates with three repeats and treated with PTL for 24 h. HCT116 and SW480 cells are seeded in 96-well plates and then transfected as follows: Wnt/β-catenin signaling responsive Firefly luciferase reporter plasmid SuperTOPFlash (80 ng/well) and Renilla reporter plasmid (8 ng/well). After 3-h transfection, cells are exposed to various concentrations of PTL for 24 h and then lysed. Both Firefly and Renilla luciferase activities are measured using the Dual-Luciferase Reporter Assay kit.
Animal Study:

[5]
  • Animal Models

    Female athymic BALB/c nude mice of xenograft gastric cancer (GC) model

  • Dosages

    4 mg/kg/day

  • Administration
