Biological Activity

Description OG-L002 is a potent and specific LSD1 inhibitor with IC50 of 20 nM in a cell-free assay, exhibiting 36- and 69-fold selectivity over MAO-B and MAO-A, respectively.
Features This selective LSD1 inhibitor was discovered in 2013. Potential for use in viral diseases such as HSV and VZV.
LSD1 [1]
(Cell-free assay)
20 nM
In vitro

OG-L002 potently inhibits HSV IE gene expression in both HeLa and HFF cells with IC50 of ~10 μM and ~3 μM , respectively. OG-L002 treatment (50 μM ) results in the reduced production of progeny virus with no significant toxicity in HeLa or HFF cells. OG-L002 (50 μM ) increases the levels of repressive chromatin on viral IE gene promoters. In addition, OG-L002 also represses the expression of hCMV IE genes and adenovirus E1A gene. [1]

In vivo OG-L002 (6 to 40 mg/kg) represses HSV primary infection in a dose-dependent manner in a mouse model. Moreover, OG-L002 also represses HSV reactivation from latency in a mouse ganglion explant model. [1]

LSD1 demethylation assay:

Human recombinant LSD1 protein is incubated with dimethylated H3K4 peptide as the substrate in the presence of various concentrations of lead compound inhibitors (0 to 75 μM ) or control tranylcypromine. The demethylase activity is measured by the release of H2O2 produced during the catalytic process, using the Amplex red peroxide/peroxidase-coupled assay kit. Each reaction is done in triplicate. The maximum LSD1 demethylase activity is obtained in the absence of inhibitor and corrected for background fluorescence. The Ki (IC50) of OG-L002 is calculated as half-maximal activity.

  • Cell lines: HeLa and HFF cells
  • Concentrations: ~50 μM
  • Incubation Time: 12 hours
  • Method: HeLa or HFF cells are treated with the indicated concentrations of saponin (positive control) or compound OG-L002 for 12 hours. Cytotoxicity is determined using conditions recommended by the manufacturer and expressed as ratios to the cytotoxicity of the DMSO control.

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.
