  • Upper panel: qPCR analysis of CDX2-negative HT29 cells treated with increasing concentrations of the DNMTi decitabine (1.25 μM, 2.5 μM, 5 μM, 10 μM) for 48 h and increasing concentrations of the HDAC4/5i LMK-235 (5 nM, 10 nM, 20 nM, 40 nM, 80 nM). Data were normalized to the HMBS housekeeping gene and are shown as n-fold regulation compared with DMSO-treated cells. MWU: ***p < 0.001, (n = 4). Lower panel: CDX2 Western blot analysis of the three highest concentrations for both compounds of HT29 cells treated as above. Total protein is shown as a loading control. Percentage indicates amount of protein normalized to respective DMSO controls

In vitro

LMK-235 causes HDAC inhibition with IC50 of <1 μM in human cancer cell lines with different sensitivity towards cisplatin. In breast cancer cell line MDA-MB-231, tongue cancer cell line Cal27, and esophagus cell line Kyse510 cell line, LMK-235 displays a high cytotoxicity, and markedly enhances the cytotoxicity of cisplatin. [1] In addition, LMK-235 also shows nanomolar activity against multiple malaria parasite life cycle stages. [2]

+ Expand

HDAC IC50 Profiling:

The in vitro inhibitory activity of compounds against seven human HDAC isoforms (1, 2, 4 C2A, 5 C2A, 6, 8, and 11) are performed with a fluorescent based assay according to the company’s standard operating procedure. The IC50 values are determined using 10 different concentrations with 3-fold serial dilution starting at 10 μM. TSA and vorinostat are used as reference compounds.

  • Cell lines: A2780, Cal27, Kyse510, and MDA-MB-231 cell lines
  • Concentrations: ~10 μM
  • Incubation Time: 72 hours
  • Method:

    The rate of cell survival under the action of test substances is evaluated by an improved MTT assay. The assay is based on the ability of viable cells to metabolize yellow MTT to violet formazan that can be detected spectrophotometrically. In brief, A2780, Cal27, Kyse510, and MDA-MB-231 cell lines are seeded at a density of 5000, 7000, 8000, and 10 000 cells/well in 96-well plates. After 24 h, cells are exposed to increased concentrations of the test compounds. Incubation is ended after 72 h, and cell survival is determined by addition of MTT solution (5 mg/mL in phosphate buffered saline). The formazan precipitate is dissolved in DMSO. Absorbance s measured at 544 and 690 nm in a FLUOstar microplate reader.

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.
