ABSTRACT
Alzheimer's disease, the commonest cause of dementia, is a growing global health concern with huge implications for individuals and society. Stroke has still been a significant challenge in clinics for a long time, which is the second leading cause of death in the world, especially ischemic stroke. Both Alzheimer's disease and stroke are closely related to oxidative stress and HIF-1 signaling pathways in nerve cells. Herein, we describe our structure-based design, synthesis, and biological evaluation of a new class of 8-biaryl-2,2-dimethylbenzopyranamide derivatives as natural product derivatives. Our efforts have resulted in the discovery of highly potent neuroprotective agents, as exemplified by compound D13 as a HIF-1α inhibitor, which significant improvement in the behavior of Alzheimer's disease mice and shows great potential improvement of brain infarct volume in pMCAO model rats, improves the increase of blood-brain barrier permeability after cerebral ischemia in rats, neuroprotective effect, reduce the level of apoptotic cells in rats after cerebral ischemia, better than Edaravone.
