Description

ML239 is a potent and selective inhibitor of breast cancer stem cells, with an IC50 of 1.16 μM.

In Vitro

ML239 (Compound 7j) is a potent and selective inhibitor of breast cancer stem cells, with an IC50 of 1.16 μM, with ～24-fold selectivity against the control cell line[1]. ML239 inhibits breast cancer stem-like cells, most likely through activation of fatty acid desaturase 2 (FADS2). ML239 is cytotoxic to NCIH661 cells, and FADS2 knockdown reduces ML239 cytotoxicity, and furthermore, FADS2 inhibitor SC-26196 also reduces ML239 cytotoxicity in cancer cell lines (CCLs)[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (7.21 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay
[2]

Cancer cell lines (CCLs) are plated at a density of 500 cells/well in white opaque tissue-culture-treated Aurora 1536-well MaKO plates in the provider-recommended growth media using a highly automated platform. Compounds (ML239) are added by acoustic transfer using a Labcyte Echo 555. 24 hours after plating. The effects of small molecules (ML239) are measured over a 16-point concentration range (two-fold dilution) in duplicate. DMSO is used at a constant concentration of 0.33%, including vehicle-only control wells. As a surrogate for viability, cellular ATP levels are assessed 72 hours after compound transfer by addition of CellTiterGlo followed by luminescence measurement using a ViewLux Microplate Imager. Duplicates are averaged and luminescence values normalized to vehicle (DMSO) treatment and background (media-only) wells[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
