體外研究活性 | 在時間分辨熒光能量共振轉移試驗中,TPCA-1抑制人IKK-2活性,IC50為17.9 nM。TPCA-1被證明是ATP競爭性的。此外,TPCA-1對IKK-1和JNK3分別表現(xiàn)出400 nM和3600 nM的IC50值。TPCA-1濃度依賴性抑制TNF-α,IL-6,和IL-8的產(chǎn)生,IC50值分別為170,290,和320 nM。[1] TPCA-1抑制膠質瘤細胞增殖,以及TNF誘導的RelA (p65)核轉運和NFκB依賴性IL8基因表達。重要的是,TPCA-1抑制IFN誘導的基因表達,完全抑制MX1和GBP1基因表達,而對ISG15表達僅具有很小的作用。[2] |

重組人IKK-2 (殘基1-756)在桿狀病毒中以N端GST標記的融合蛋白表達,其活性使用時間分辨熒光共振能量轉移測定法進行評估。簡而言之,IKK-2 (終濃度5 nM)在試驗緩沖液(50 mM HEPES,10 mM MgCl2,1 mM CHAPS,pH 7.4,1 mM DTT 和0.01% w/v BSA)中稀釋,加入包含不同濃度化合物或二甲基亞砜(DMSO)載體(終濃度3%)的孔中。加入總體積為30 μL 的GST-IκBα 底物(終濃度25 nM)/ATP (終濃度1 μM)起始反應。反應在室溫下培育30分鐘,然后加入15 μL 50 mM EDTA終止。加入包含W-1024銪螯合物標記的抗磷酸絲氨酸- IκBα-32/36單克隆抗體12C2,和別藻藍素標記的抗-GST抗體的檢測試劑(15 μL)緩沖液(100 mM HEPES,pH 7.4,150 mM NaCl,和0.1% w/v BSA),反應在室溫下進一步培養(yǎng)60分鐘。GST- IκBαis的磷酸化程度以特定665-nm能量轉移信號的比率,參考銪620-nm信號,使用Packard探測酶標儀測量。 | ||||
