LSD1 inhibitor IMG-7289
An orally-available, irreversible inhibitor of lysine-specific demethylase 1 (LSD1), with potential antineoplastic activity. Upon administration, IMG-7289 binds to and inhibits LSD1, a demethylase that suppresses the expression of target genes by converting the di- and mono-methylated forms of lysine at position 4 of histone H3 (H3K4) to mono- and unmethylated H3K4. LSD1 inhibition enhances H3K4 methylation and increases the expression of tumor suppressor genes. In addition, LSD1 demethylates mono- or di-methylated H3K9 which increases gene expression of tumor promoting genes; thus, inhibition of LSD1 also promotes H3K9 methylation and decreases transcription of these genes. Altogether, this may lead to an inhibition of cell growth in LSD1-overexpressing tumor cells. LSD1, an enzyme belonging to the flavin adenine dinucleotide (FAD)-dependent amine oxidase family is overexpressed in certain tumor cells and plays a key role in the regulation of gene expression, tumor cell growth and survival. Check for active clinical trials using this agent. (NCI Thesaurus)
