生物活性 | MKC8866, a salicylaldehyde analog, is a potent, selectiveIRE1RNaseinhibitor with anIC50of 0.29 μM in human vitro. MKC8866 strongly inhibits Dithiothreitol-induced X-box-binding protein 1-spliced (XBP1s) expression with anEC50of 0.52 μM and unstresses RPMI 8226 cells with an IC50of 0.14 μM[1]. MKC8866 inhibitsIRE1RNase in breastcancercells leading to the decreased production of pro-tumorigenic factors and it can inhibits prostatecancer(PCa) tumor growth[2]. |
IC50& Target | IC50: 0.29 μM (IRE1 RNase)[1] |
体外研究 (In Vitro) | MKC8866 (20 μM; 6 days) decreases proliferation of all breast cancer cell lines[2]. MKC8866 (20 μM; 48 hours) reduces the number of cells entering S phase[2]. MKC8866 (0.2-10 μM; 3 days) suppresses the viability of all four cell lines in a dose-dependent manner under normal conditions, with the most robust effect in LNCaP cells[1]. MKC8866 (20 μM; 72 hours) is sufficient to completely block NSC 125973-induced expression of XBP1s[1].
