    Product Description

    CPI-169 is a selective EZH2 inhibitor with IC50 values of 0.24, 0.51, and 6.1 nM for wild-type EZH2, Y641N mutant EZH2, and wild-type EZH1, respectively.1 It decreases cellular levels of H3K27me3 (EC50 = 70 nM), triggering cell cycle arrest and ultimately resulting in apoptosis in a large panel of non-Hodgkin’s lymphoma (NHL) cell lines.1 With subcutaneous administration of 200 mg/kg/twice a day, CPI-169 was shown to inhibit tumor growth in a NHL xenograft model, reducing global H3K27me3.1 It has also been shown to synergize with the B-cell lymphoma 2 inhibitor, ABT-199 (Item No. 16233), to suppress the growth of NHL cell lines.1
