Solubility (25°C)* In vitro Ethanol 93 mg/mL (201.05 mM)
DMSO 23 mg/mL (49.72 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 95% Corn oil
1.15mg/ml Taking the 1 mL working solution as an example, add 50 μL of 23 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
1.15mg/ml Taking the 1 mL working solution as an example, add 50 μL of 23 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 EC330 is a steroidal inhibitor of leukemia inhibitory factor (LIF, an interleukin 6 class cytokine). EC330 inhibits the LIF/LIF-R signaling and blocks the promoting effects of LIF on growth and migration of cancer cells.
Targets
LIF [1]
In vitro

EC330, a potential LIF inhibitor, inhibits the activation of STAT3, PI3K/AKT, and mTOR signaling pathways by LIF, preferentially inhibits the proliferation of cancer cells with LIF overexpression, also inhibits LIF function in promoting migration of cancer cells.[1]
In vivo

EC330 inhibits multi-functional cytokine LIF function in promoting tumor growth in vivo.[1]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    MCF7, MDA-MB231 cell lines

  • Concentrations

    --

  • Incubation Time

    24 h

  • Method

    The effect of EC330 on viability of cells with or without ectopic LIF expression was assessed in cells treated with different concentrations of EC330 for 24 h. Cell viability was determined by   the Vi-CELL counter that performs a trypan blue exclusion method. Cell proliferation was   determined by counting cell numbers daily for four days.
Animal Study:

[1]
  • Animal Models

    BALB/c nude mice model of subcutaneous xenograft tumors formed by MDA-MB231 cells with ectopic LIF expression

  • Dosages

    1 mg/kg

  • Administration
