MS8709 (EX-A11295) is a first-in-class G9a/GLP proteolysis targeting chimera (PROTAC) degrader, that induces G9a/GLP degradation in a concentration, time, and ubiquitin-proteasome system (UPS)-dependent manner, and does not alter the mRNA expression of G9a/GLP over other methyltransferases. It displays superior cell growth inhibition in prostate, leukemia, and lung cancer cells over parent G9a/GLP inhibitors.
