A-196 is a potent and selective inhibitor of SUV420H1 and SUV420H2 with IC50 values of 25 nM and 144 nM, respectively. A-196 inhibits SUV4-20 biochemically in a substrate-competitive manner. A-196 represents a first-in-class chemical probe of SUV4-20 to investigate the role of histone methyltransferases in genomic integrity.

How to use

In Vitro:

A-196 (0-5 μM; 48 hours; U2OS cells) treatment results in an increase in H4K20me1 (EC50 value of 735 nM) and a decrease in both H4K20me2 and H4K20me3 (EC50 values of 262 and 370 nM, respectively). A-196 (10 μM; 72 hours; Wild-type, Suv4-20h double knockout and inhibitortreated mouse embryonic fibroblast cells) inhibits both SUV4-20 enzymes in cells in multiple tissue types without overt toxicity.
