Chaetocin (CAT: I010970) is a natural compound isolated from the fungus Chaetomium species. It acts as a selective inhibitor of histone methyltransferase SUV39H1, leading to the inhibition of histone H3 lysine 9 (H3K9) methylation. Chaetocin exhibits pharmacological activities against various cancers by inducing apoptosis, inhibiting cell proliferation, and suppressing tumor growth. It has shown potential as an anti-cancer agent in preclinical studies, particularly in hematological malignancies such as leukemia. Chaetocin’s ability to modulate histone methylation and epigenetic processes makes it a promising candidate for further exploration in cancer therapy and epigenetic-based treatments.
