      生物活性

      產(chǎn)品描述 GSK126 (GSK2816126A, GSK2816126) 是一種有效的,高選擇性EZH2 methyltransferase抑制劑,IC50為9.9 nM,對 EZH2 的選擇性比其他20種人甲基轉(zhuǎn)移酶高1000多倍。
      靶點
      EZH2 [1]
      (Cell-free assay)
      9.9 nM
      體外研究(In Vitro)
      體外研究活性 在體外,EZH2野生型和突變型DLBCL細胞系中,GSK126最有效地抑制H3K27me3,其次是H3K27me2。GSK126也能有效抑制EZH2突變型DLBCL細胞系的增殖,并誘導(dǎo)敏感細胞系中EZH2靶基因的轉(zhuǎn)錄激活。[1]在A687V EZH2突變細胞中,GSK126處理導(dǎo)致總體H3K27me3減少,強基因活化,胱天蛋白酶活化,以及增殖減少。[2]在親代H2087細胞中,GSK126抑制VEGF-A和磷酸化Ser(473)-AK的表達,因此引起對細胞增殖,遷移和代謝的抑制。[3]
      激酶實驗 EZH2 試驗
      制備包含野生型或突變型EZH2的5個組分的PRC2復(fù)合物(Flag–EZH2,EED,SUZ12,AEBP2,RbAp48)。GSK126在DMSO中溶解,以0.6?nM到300?nM的濃度測試,終DMSO濃度為2.5%。體外實驗中,相對于更傾向H3K27me0作為底物的野生型EZH2,EZH2 Y641傾向于H3K27me2作為底物,而對H3K27me0 或H3K27me1的活性很低。A677G不同于EZH2的野生型和Y641突變型,它有效地使H3K27me0,H3K27me1,和H3K27me2甲基化;因此,組蛋白H3多肽(殘基21–44;終濃度10?μM)與 K27me0 (野生型,A677G EZH2),K27me1 (A677G EZH2),或K27me2 (A677G,Y641N,Y641C,Y641H,Y641S 和 Y641F EZH2)用作甲基轉(zhuǎn)移酶底物。GSK126加入到板中,然后加入6?nM EZH2復(fù)合物和多肽。GSK126的效能處于或接近[SAM] = Km下進行的試驗的緊密結(jié)合界限,IC50值在競爭性底物SMA相對其Km(7.5 μM SAM,而 SAM Km為0.3?μM)較高濃度下測量。在這些條件下,酶濃度的作用相對非常小,可以計算出Ki的精確估計值。反應(yīng)通過[3H]-SAM起始,培養(yǎng)30分鐘,加入500倍過量未標記的SAM淬滅反應(yīng),甲基化產(chǎn)物肽在磷酸纖維素過濾器上根據(jù)供應(yīng)商提供的MSPH 多屏幕平板進行捕獲。表觀Ki值使用競爭性抑制劑的Cheng–Prusoff關(guān)系計算。IC50=Ki (1+[S]/Km)+[E]/2,其中E是酶,S為底物。
      細胞實驗 細胞系 46 淋巴瘤細胞系
      濃度 0~10 μM
      孵育時間 6天
      方法

      所有細胞系的最優(yōu)細胞接種根據(jù)經(jīng)驗確定,通過檢測在384孔板式中寬范圍的接種密度以確定可以增殖6天的試驗條件。然后細胞以最佳接種密度接種24小時,再用20點兩倍連續(xù)稀釋的GSK126 或0.15% DMSO處理(一式兩份)。板在37℃下在5% CO2中培養(yǎng)6天。然后將細胞用CellTiter-Glo (CTG)裂解,化學(xué)發(fā)光信號用TECAN Safire2酶標儀檢測。此外,未處理板中的細胞在化合物加入(T0)時進行采集以定量初始細胞數(shù)。處理6天后得到的CTG值表示為T0值的百分比,并以化合物濃度為橫坐標繪圖。數(shù)據(jù)擬合為4參數(shù)方程以產(chǎn)生濃度反應(yīng)曲線,并測定抑制50%生長(生長 IC50)的GSK126濃度。
