Recent advances in neuroscience have revealed a greater, in-depth understanding of the complexities associated with memory. Contemporary theories hold that an integral relationship between memory formation, stabilization and consolidation revolve around plasticity of neuronal networks. The

Huperzine A (HupA), a novel Lycopodium alkaloid isolated from Chinese folk medicine Huperzia serrata (Qian Ceng Ta), is a potent, selective and well-tolerated inhibitor of acetylcholinesterase (AChE). It has been proven to significantly improve the learning and memory impairment in Alzheimer's

Neonatal hypoxia-ischemia (HI) is an etiologic component of several neurologic pathologies associated to cognitive impairment. The mechanisms involved in HI-induced tissue damage start immediately after HI and extend for days. Acetylcholine is an important neurotransmitter in the central nervous

Alkaloids having acetylcholinesterase (AChE) inhibitory activity are commonly found in traditional Chinese medicine (TCM); for example, berberine from Coptis chinensis, galantamine from Lycoris radiata, and huperzine A from Huperzia serrata. In practice of TCM, Stephaniae

Huperzine A, alkaloid from the Chinese herbal medicine Qian Ceng Ta, which is prepared from the moss Huperzia serrata, has been used in China for centuries to treat fever and inflammation. Huperzine A is a strong inhibitor of cholinesterases with high selectivity to acetylcholinesterase and in China

Huperzine A is an alkaloid which was first isolated from Huperzia serrata (Thumb) Trev by Zhejiang Academy of Medical Sciences and Shanghai Institute of Materia Medica, Chinese Academy of Sciences. It exhibits a significant anticholinesterase activity and has been used on myasthenia gravis patients.

Huperzine A (HupA) is an effective inhibitor of acetylcholinesterase and has attracted great interest as a therapeutic candidate for Alzheimer's disease. However, the use of HupA is limited by resource scarcity as well as by its low yields from Huperzia serrata, its primary plant source.

Free radical-induced oxidative damage is implicated in the pathogenesis of neurodegenerative disorders, and antioxidants are presumably of therapeutic value in such diseases. Our previous data indicated that free radicals are strongly associated with brain aging and also play an important role in

Hup A, a novel alkaloid isolated from Chineses herb Huperzia serrata, is a potent and selective inhibitor of AChE, with a rapid absorption and penetration into the brain in experimental animals. The inhibition is reversible with a longer duration of action. Hup A exhibited memory-enhancing

Imbalance between production and scavenging of free radicals and other reactive oxygen species (ROS) is a component of many diseases, but it is especially important in aging-related diseases of the central nervous system. Oxidative stress-induced neuronal dysfunction plays an important role in the

Two new tetranorlabdane diterpenoids, named botryosphaerins G (1) and H (2), were isolated from the solid fermentation products of Botryosphaeria sp. P483 along with seven known tetranorlabdane diterpenes (3-9). Their structures were elucidated by extensive analysis, including 1D and 2D nuclear

Dementia pathologies such as Alzheimer's disease (AD) are reaching epidemic proportions, yet they are not successfully managed by effective symptomatic treatments. Only five drugs have been developed to alleviate cognitive symptoms, and more effective and safe treatments are needed for both the

Huperzine A (Hup A) is a lycopodium alkaloid from Huperzia serrata, which has been used as a therapeutic agent in several neurological disorders. Despite the diverse pharmacological activities Hup A has, its role in hippocampal neurogenesis remains to be established. This study showed that Hup A not

Huperzine A (HUP-A), first isolated from the Chinese club moss Huperzia serrata, is a potent, reversible and selective inhibitor of acetylcholinesterase (AChE) over butyrylcholinesterase (BChE) (Life Sci. 54: 991-997). Because HUP-A has been shown to penetrate the blood-brain barrier, is more stable

Huperzine A (HupA), isolated from Chinese herb Huperzia serrata, is a potent, highly specific and reversible inhibitor of acetylcholinesterase. It has been found to reverse or attenuate cognitive deficits in a broad range of animal models. Clinical trials in China have demonstrated that HupA
