Gintemetostat

An orally available small molecule inhibitor of the histone-lysine N-methyltransferase nuclear receptor-binding SET domain protein 2 (NSD2; MMSET; WHSC1), with potential antineoplastic activity. Upon oral administration, gintemetostat selectively targets and binds to NSD2, and inhibits its catalytic activity and the mono- and di-methylation of histone H3 lysine 36 (H3K36). This modulates the expression of genes involved in cellular processes including cellular proliferation, which may lead to decreased growth of cancer cells. NSD2, a member of the NSD family of histone lysine methyltransferase enzymes that catalyzes the mono- and di-methylation of H3K36, is overexpressed and dysregulated in many types of cancers.
