描述 Donepezil, as a acetylcholinesterase (AChE) inhibitors, inhibits AChE activity thereby increasing the acetylcholine (ACh) levels. Pretreatment with donepezil suppressed the TNFα-induced sustained intracellular Ca2+ elevation in both rat HAPI and mouse primary microglial cells[3]. Exposure to donepezil resulted in a rapid and reversible block of Kv1.5 currents, with an IC50 value of 72.5 μM. Donepezil can directly block Kv1.5 channels in its open and closed states[4]. Donepezil itself enhances neurogenesis and improves cognitive function following TBI(Traumatic Brain Injury), even when injury-induced neurogenesis was inhibited[5].
