在時間分辨熒光能量共振轉(zhuǎn)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(zhì)瘤細(xì)胞增殖,以及TNF誘導(dǎo)的RelA (p65)核轉(zhuǎn)運和NFκB依賴性IL8基因表達(dá)。重要的是,TPCA-1抑制IFN誘導(dǎo)的基因表達(dá),完全抑制MX1和GBP1基因表達(dá),而對ISG15表達(dá)僅具有很小的作用。[2]
