Description

technical field [0001] The invention belongs to the field of medicine and chemical industry, and specifically relates to tacrine-bifendate hybrid compound, its preparation method and application. Background technique [0002] Alzheimer's disease (Alzheimer disease, AD) is a neurodegenerative disease, discovered by the German neuropathologist Alois Alzheimer in 1907, manifested as the degeneration of the central nervous system, neurofibrillary tangles and cellular The pathological features of senile plaques appear outside. Clinically, patients gradually develop memory loss, cognitive dysfunction, behavioral abnormalities, and social barriers, etc., and usually the condition is progressively aggravated until they completely lose the ability to live independently. [0003] Alzheimer's is a very common disease among the elderly, and has become the fourth leading cause of death in the elderly after tumors, heart disease, and cerebrovascular diseases. With the acceleration of th...
