Customer Review

    MKC8866 purchased from MCE. Usage Cited in: Cancer Lett. 2020 Oct 10;490:76-88.  [Abstract]

    RH30 and RD cells are treated with MKC8866 (20 μM) and/or AMGEN44 (2 μM) for 72 hours and Western blot confirmes IRE1 and PERK signalling inhibition. In cells treated with AMGEN44 alone or in combination with MKC8866, PERK phosphorylation is reduced and p-eIF2α protein levels are diminished. In cells treated with MKC8866 alone or in combination with AMGEN44, XBP1s protein levels are completely abolished.

    生物活性

    MKC8866, a salicylaldehyde analog, is a potent, selective IRE1 RNase inhibitor with an IC50 of 0.29?μM in human vitro. MKC8866 strongly inhibits Dithiothreitol-induced X-box-binding protein 1-spliced (XBP1s) expression with an EC50 of 0.52?μM and unstresses RPMI 8226 cells with an IC50 of 0.14?μM[1]. MKC8866 inhibits IRE1 RNase in breast cancer cells leading to the decreased production of pro-tumorigenic factors and it can inhibits prostate cancer (PCa) tumor growth[2].

    IC50 & Target

    IC50: 0.29?μM (IRE1 RNase)[1]

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
