OG-L002

Lysine-specific demethylase 1 (LSD1) is a protein lysine demethylase that specifically demethylates histone H3 lysine 4 (H3K4) and H3K9, resulting in transcriptional repression.¹ Host LSD1 is also recruited by certain viruses to limit H3K9 methylation, which can repress viral genes necessary for infection.² OG-L002 is a potent inhibitor of LSD1 (IC₅₀ = 0.02 µM) that less effectively inhibits the monoamine oxidases A (MAO-A) and MAO-B (IC₅₀s = 1.38 and 0.72 µM).² It blocks the expression of immediate early (IE) genes of herpes simplex virus (HSV) in HeLa cells but not that of cellular control genes.² OG-L002 also reduces the expression of human cytomegalovirus IE genes and adenovirus E1A gene in mammalian cells.² It is effective in vivo, repressing HSV primary infection in mice and blocking HSV reactivation from latency in a mouse ganglion explant model.²
