Sophocarpine Attenuates Cognitive Impairment and Promotes Neurogenesis in a Mouse Model of Alzheimer's Disease.

Introduction: Alzheimer's disease (AD), which is characterized by abnormal deposition of amyloid-β (Aβ) plaques and impaired neurogenesis and cognition, still lacks an optimally effective therapeutic agent for its management, and mounting evidence has shown that inflammatory processes are implicated in AD. Sophocarpine has been reported to exert inflammation-regulating effects in various diseases. However, whether sophocarpine can exert anti-neuroinflammatory and neuroprotective effects in AD remains unclear.

β-Sitosterol treatment attenuates cognitive deficits and prevents amyloid plaque deposition in amyloid protein precursor/presenilin 1 mice.

Alzheimer's disease (AD) is the most common neurodegenerative disorder causing dementia worldwide, and is mainly characterized by aggregated β-amyloid (Aβ). Increasing evidence has shown that plant extracts have the potential to delay AD development. The plant sterol β-Sitosterol has a potential role in inhibiting the production of platelet Aβ, suggesting that it may be useful for AD prevention.
