Huperzine A and Its Neuroprotective Molecular Signaling in Alzheimer’s Disease

Summary: Huperzine A, an alkaloid from the club moss Huperzia serrata, has been traditionally used in Chinese medicine to treat dementia and shows promise for Alzheimer’s disease due to its neuroprotective properties and ability to inhibit acetylcholinesterase. This study reviews Huperzine A’s interactions with various molecular pathways, including Wnt signaling, synaptic mechanisms, amyloid precursor protein processing, amyloid-β accumulation, and mitochondrial protection, aiming to provide a comprehensive understanding of its effects on Alzheimer’s disease.

Ginkgolides and Huperzine A for complementary treatment of Alzheimer’s disease

Summary: Alzheimer’s disease lacks successful pharmacological treatments, but certain plant-based therapies like Ginkgo biloba (EGb 761®) and Huperzine A have shown promise in improving cognitive function and neuropsychiatric symptoms in patients. This review highlights the positive outcomes of these interventions in the last decade, supporting their potential use in Alzheimer’s therapy.

Delineating biosynthesis of Huperzine A, A plant-derived medicine for the treatment of Alzheimer’s disease

Summary: Huperzine A (HupA), a treatment for Alzheimer’s, is currently extracted from the slow-growing plant Huperzia serrate, which is unable to meet growing demand. This review explores alternative methods for producing HupA, including biosynthesis and pathway engineering, detailing the latest advancements in synthetic pathways, key enzymes, and catalytic mechanisms.

The effects of Huperzine A on dementia and mild cognitive impairment: An overview of systematic reviews

Summary: This study overviewed existing research on Huperzine A’s effectiveness for dementia and mild cognitive impairment, finding it may help Alzheimer’s patients with cognitive function and daily activities but lacks sufficient evidence for other types of cognitive impairments. No serious side effects were reported, but the study calls for more high-quality, long-term research to confirm the results.

Huperzine a ameliorates sepsis-induced acute lung injury by suppressing inflammation and oxidative stress via α7 nicotinic acetylcholine receptor

Summary: This study found that Huperzine A (HupA) can improve survival and reduce lung injury in sepsis-induced acute lung injury by activating the α7 nicotinic acetylcholine receptor (α7nAChR) in mice. The research demonstrated that HupA reduces inflammation and oxidative stress, alters immune cell composition, regulates gut microbiota, and promotes beneficial compounds, suggesting a promising new treatment approach for sepsis.

Administration of Huperzine A microspheres ameliorates myocardial ischemic injury via α7nAChR-dependent JAK2/STAT3 signaling pathway

Summary: The study investigated whether a sustained-release formulation of huperzine A (a type of acetylcholinesterase inhibitor, AChEI) could protect against heart damage in a mouse model of myocardial ischemia (heart attack). The results showed that huperzine A microspheres (HAM) reduced markers of heart injury and inflammation, suggesting that continuous inhibition of AChE might protect the heart by regulating specific anti-inflammatory pathways.
