Target	Ki: <0.1 nM (Y641N EZH2)[1].
In Vivo	PF-06821497 (compound 23a: 100 mg/kg, PO twice daily for 31 days) treatment results in significant inhibition of tumor growth, and the the tumor regressition effect can be sustained for another 40 days after the terminal administration[1]. PF-06821497 with the dose of 300 mg/kg has minimal impact on animal body weights[1]. Animal Model: Mice bearing Karpas-422 DLBCL tumor xenografts (which contain the Y641N EZH2 mutation)[1]. Dosage: 100 mg/kg and 300 mg/kg. Administration: PO twice daily for 31 days. Result: 100 mg/kg dose resulted in significant inhibition of tumor growth and 300 mg/kg dose minimal effected animal body weights.
