MAPT and Alzheimer disease: Through upregulating HSPB1 chaperone to reduce Tau misfolding, and enhancing NRF2 and CREB pathways to reduce ROS and apoptosis in ΔK280 TauRD‐DsRed SH‐SY5Y cells, as well as promoting neuron survival and cognitive function in hyperglycemic 3×Tg‐AD mice, LM‐031 (3‐benzoyl‐5‐hydroxychromen‐2‐one) displays potential for Alzheimer’s disease treatment.
