Biological Activity: Chaetocin inhibits SUV39H1 with an IC50 = 0.8 µM, G9a with an IC50 = 2.5µM , and DIM5 with an IC50 = 3 µM .
CAS Number: 28097-03-2
Description: Chaetocin is an inhibitor of histone methyltransferases (HMTs) including SUV39H1 and Lys9-specific HMTs such as G9a. It also has some inhibitory effects on SET7, EZH2, and SET7/9. Chaetocin can also induce cellular oxidative stress, selectively killing cancer cells and rapidly-proliferating primary cells. It is a fungal myotoxin. The inhibitor is useful in epigenetics and cancer research.
