EPZ031686 is the first SMYD3 inhibitor.Set and Mynd Domain containing 3 (SMYD3), a lysine methyltransferase (KMT) expressed at high levels in a number of different cancer histologies, is reported to be associated with a poor clinical prognosis.In vitro: EPZ031686 was the first SMYD3 inhibitor found to show double-digit nanomolar cellular activity. In addition, EPZ031686 displayed noncompetitive inhibition to both SAM and MEKK2 with a Ki = 1.2 and 1.1 nM, respectively. Moreover, EPZ031686 showed less than 30% inhibition against 16 histone methyltransferase targets at a 10 μM [1]. Other sizes are also available. Please inqury us for quote.
