Information Dehydroevodiamine (DHE), a major phytochemical in fruits of Evodia rutaecarpa, can inhibitAChE. It has hypotensive and neuroprotective effects and modulates nitric oxide production. Targets AChE In vitro Dehydroevodiamine·HCl (DHED) treatment significantly recovers the decreases in the levels of neural cell adhesion molecule (NCAM) proteins caused by stress and the decreases in cell viability. It decreases intracellular calcium levels in primary cortical neurons. In vivo Dehydroevodiamine·HCl (DHED) can improve stress-induced memory impairments and depression-like behaviors. DHED significantly improves learning and memory in the Aβ 1-42 -infused rat model. Antiamnestic effects of DHED occur through an improvement of learning and memory and an inhibition of neuronal dysfunction in a scopolamine-induced amnesic rat model. Furthermore, Dehydroevodiamine·HCl (DHED) has hypotensive and neuroprotective effects and modulates nitric oxide production.
