S27-1047
S27-1047 is a brain-penetrant, potent and selective BChE (eqBChE IC50 = 7.16 nM; hBChE IC50 = 296.10 nM) inhibitor and Nrf2 activator. S27-1047 can directly bind Keap1, disrupt Keap1-Nrf2 interaction (FP IC50 = 36.87 nM), enhance antioxidant enzyme expression and activate the GSH-GPX4 axis to inhibit Aβ-induced ferroptosis. S27-1047 can protect against oxidative stress and neuroinflammation. S27-1047 can be used in Alzheimer's disease research.

S27-1047 (10 μM; 0-24 h) can significantly upregulate the expression of Nrf2 downstream proteins in a time-dependent manner and the effect is more obvious in 5 to 10 h [1].
S27-1047 (10 μM; 0-24 h) shows low neurotoxicity in L02 cells , BV2 microglia cells and SH-SY5Y cells[1].
S27-1047 (1-20 μM; 6 h) can significantly increase the level of Nrf2 and its downstream protein (HO-1, NQO1 and GCLM) in a dose-dependent manner and induces a nearly 5-fold increasein Nrf2 protein expression at a concentration of 5 μM[1].
S27-1047 (10μM) exhibits antioxidant activity in an Nrf2-dependent manner[1].
S27-1047 (10 μM; 0-24 h) reveals significant nuclear accumulation of Nrf2 during 2-5 h treatment periods[1].
S27-1047 (10 μM; 2 h; 37-51 °C) induces a pronounced thermal stabilization of Keap1[1].
S27-1047 (10 μM) significantly promotes Keap1 degradation, consequently upregulating Nrf2 protein levels and effectively disrupting the Keap1-Nrf2 complexformation (FP IC50 = 36.87 nM)[1].
S27-1047 (1-20 μM; pretreatment for 2 h + co-incubation with Aβ1-42 for 24 h) demonstrates a potent, dose-dependent cytoprotective effect against H2O2-induced oxidative damage in L02 cells[1].
S27-1047 (1-20 μM; pretreatment for 2 h + co-incubation with Aβ1-42 for 24 h) demonstrates a dose-dependent cytoprotective effect against toxic Aβ fibril-induced cytotoxicity in the human neuroblastoma SH-SY5Y cells[1].
S27-1047 (10 μM; pretreatment for 24 h + co-incubation with Aβ1-42 for 24 h) significantly attenuats ROS generation without affecting cellular viability[1].
S27-1047 (10 μM) significantly inhibits the upregulation of tumor necrosis factor-alpha (TNF-α) in LPS-stimulated BV2 microglia cells[1].
S27-1047 (10 μM; pretreatment for 24 h + co-incubation with Aβ1-42 for 24 h) significantly attenuated lipid peroxidation in SH-SY5Y cells. S27-1047 robustly activates the System Xc- /GSH/GPX4 axis, a critical antioxidant pathway, leading to marked increases in GSH levels and GPX4 activity. S27-1047 can mitigate Aβ-induced ferroptosis[1].
