Keap1-Nrf2-IN-30
Keap1-Nrf2-IN-30 is an orally active, blood-brain barrier-permeable Keap1-Nrf2 protein-protein interaction inhibitor with a Keap1 Kd value of 157 nM. Keap1-Nrf2-IN-30 selectively inhibits the Keap1-Nrf2 protein-protein interaction, promotes Nrf2 nuclear translocation, suppresses induced ferroptosis, reduces the expression of Aβ and p-Tau, and upregulates the expression of GPX4 and SLC7A11. Keap1-Nrf2-IN-30 upregulates the expression of HO-1 and NQO1, alleviates neuronal damage, and improves cognitive and spatial memory deficits. Keap1-Nrf2-IN-30 can be used in the research of Alzheimer's disease.

Keap1-Nrf2-IN-30 (compound 4-95) binds directly to purified Keap1 protein, with a KD value of 157 nM[1].
Keap1-Nrf2-IN-30 (8-32 μM; 8 h) dose-dependently restores the viability of HT-22 and SH-SY5Y cells undergoing ferroptosis induced by RSL-3 (HY-100218A) and Erastin (HY-15763)[1].
Keap1-Nrf2-IN-30 (32 μM) protects SH-SY5Y cells against Erastin-induced ferroptosis and lipid peroxidation in a Keap1-Nrf2-GPX4 axis-dependent manner, as knockdown of Keap1 or GPX4 abolishes its protective effect[1].
Keap1-Nrf2-IN-30 (32 μM) upregulates the protein expression of SLC7A11 and GPX4 in Erastin-induced ferroptotic SH-SY5Y cells in a Keap1-dependent manner, as Keap1 knockdown abolishes its effect[1].
Keap1-Nrf2-IN-30 (8-32 μM) dose-dependently restores GSH levels and reduces MDA levels and lipid peroxidation levels in HT-22 and SH-SY5Y cells undergoing Erastin-induced ferroptosis; it also inhibits ferroptotic morphological changes, cell death and mitochondrial damage[1].
Keap1-Nrf2-IN-30 (8-32 μM) upregulates the protein expression of GPX4 and SLC7A11 in a dose-dependent manner in Aβ1-42-treated SH-SY5Y cells, reduces Aβ accumulation and excessive phosphorylation of Tau; it activates the Keap1-Nrf2 pathway in a dose-dependent manner in Aβ1-42-treated SH-SY5Y cells by promoting Nrf2 nuclear translocation and upregulating downstream targets HO-1 and NQO1[1].
