Acetylcholinesterase (AChE) inhibitors have been used for the symptomatic treatment of Alzheimer's disease. Eleven whole plants from Panama belonging to the Lycopodiaceae family have been screened for their anticholinesterase inhibitory and antioxidant activities by a thin-layer chromatography (TLC) bioautography method.

The acetylcholinesterase inhibitor (-)-huperzine A was synthesized from (S)-4-hydroxycyclohex-2-enone in 17 steps by a route that involved two cyclobutane fragmentations. The first of these employed a retro-aldol cleavage to generate the α-pyridone ring of huperzine A, and the second invoked

Alzheimer's disease (AD) is a neurodegenerative disorder marked by progressive loss of memory and cognitive function. One of the new approaches for treating AD is direct stimulation of nicotinic acetylcholine receptors (nAChRs) in the brain. α4β2-nAChR agonists have shown promising

Diverse mechanisms including activation of NMDA receptors, microglial activation, reactive astrogliosis, loss of descending inhibition, and spasticity are responsible for ∼40% of cases of intractable neuropathic pain after spinal cord injury (SCI). Because conventional treatments blocking individual mechanisms elicit only
