OG-L002 (CAS 1357302-64-7)

OG-L002 is a selective inhibitor of the enzyme lysine-specific demethylase 1 (LSD1, also known as KDM1A). LSD1 is a histone demethylase that plays a crucial role in the regulation of gene expression by removing methyl groups from lysine 4 of histone H3 (H3K4). This demethylation alters the chromatin structure, typically leading to transcriptional repression of genes. The primary mechanism of action of OG-L002 involves the inhibition of LSD1. By binding to the active site of LSD1, OG-L002 prevents the enzyme from interacting with its histone substrates, thereby inhibiting its demethylase activity. This inhibition leads to an increase in the methylation levels of H3K4, which is often associated with an active transcriptional state. Therefore, OG-L002 can induce changes in gene expression patterns by altering the histone methylation landscape. In scientific research, OG-L002 is used extensively to study the role of histone modifications in gene regulation. Researchers use this chemical to understand how changes in histone methylation affect the expression of genes involved in various biological processes, including differentiation, development, and response to environmental stimuli. Additionally, OG-L002 serves as a tool to explore the broader implications of LSD1 activity in chromatin dynamics and epigenetic regulation. By inhibiting LSD1, researchers can investigate how this enzyme contributes to the maintenance of chromatin structure and the epigenetic mechanisms that underlie cellular memory and identity.
