生物活性

製品説明	CPI-169 は、IC50 が EZH2 WT で 0.24 nM、EZH2 Y641N で 0.51 nM、EZH1 で 6.1 nM である、強力で選択的な EZH2 阻害剤です。
in vitro	In KARPAS-422 cells, CPI-169 shows a dose-dependent inhibitory effect on cell viability, and produces synergy anti-proliferative activity when used in combination with ABT-199. In 16 out of 25 NHL cell lines, this compound also suppresses cell growth with GI50 of <5 μM.
in vivo	In mice bearing KARPAS-422 xenografts, CPI-169 (200 mg/kg, s.c.) effectively suppresses H3K27me3 levels and results in lymphoma tumor regression without affecting body weight or causing any overt adverse effects.

キナーゼアッセイ	Biochemical Assays
キナーゼアッセイ	Compound potency is also assessed through incorporation of ³H-SAM into a biotinylated H3 peptide. Specifically, PRC2 containing either EZH1 (160 pM), wt EZH2 (40 pM), or Y641N mutant EZH2 (80 pM, both EZH2 prepared in-house) is pre-incubated with 3H-SAM (0.9 µM), 2 µM H3K27me3 activating peptide (H2N-RKQLATKAAR(Kme3)SAPATGGVKKP-amide) and this compound (as 10 point duplicate dose response titrations) for 120 min in a buffer consisting of 50 mM Tris (pH 8.5), 1 mM DTT, 0.07 mM Brij-35, 0.1% BSA, and 0.8% DMSO in a total volume of 12.5 µl in a black 384 well plate. Reaction is initiated with biotinylated H3 substrate peptides (H3K27me1 for wt EZH2, H3K27me2 for Y641N mutant EZH2; H2N-RKQLATKAAR(Kmen)SAPATGGVKKP-NTPEGBiot) as a 2 µM stock in 12.5 µL and allowed to react at room temperature for 5 h. Quenching is accomplished by addition of 20 µl of STOP solution (50 mM Tris (pH 8.5), 200 mM EDTA, 2 mM SAH). 35 µL of the quenched solution is transferred to Streptavidin Flashplates, incubated overnight, washed, and read in a TopCount Reader. For titrations all compound dilutions are in DMSO, final DMSO concentrations are 0.8% (v/v), and turnover is kept to less than < 5%. IC50s are calculated using non-linear least square four parameter fits (GraphPad 6.0).
細胞アッセイ	細胞株	25 NHL cell lines
	濃度	~10 μM
	反応時間	4 d
	実験の流れ	Relative cell numbers are assessed by Cell Titer-Glo (CTG) luminescent cell viability assay using an Envision instrument. GraphPad Prism 6.0 is used for curve fitting, IC50/GI50 and Hill coefficient (H) calculations. The GI90 is calculated using the formula: EC90 = (90 /100-90)^1/H * EC50.
