Nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels involved in fast synaptic transmission. nAChRs are pentameric receptors formed from a combination of different or similar subunits to produce heteromeric or homomeric channels. The heteromeric, α9α10 nAChR subtype is well-known for its role in the auditory system, being expressed in(More)
Accumulation of the amyloid protein (Abeta) in the brain is an important step in the pathogenesis of Alzheimer's disease. However, the mechanism by which Abeta exerts its neurotoxic effect is largely unknown. It has been suggested that the peptide can bind to the alpha7 nicotinic acetylcholine receptor (alpha7nAChR). In this study, we examined the binding(More)
The consumption of flavonoid-rich foods, in particular fruits and vegetables, has been epidemiologically associated with a reduced risk of heart disease, neurodegenerative disease, cancer and other chronic diseases. Flavonoid glycosides, the main class of flavonoids, have been shown to exert CNS-mediated activities, particularly as sedative-hypnotics,(More)
Bicyclic analogues of methyllycaconitine (MLA), such as 12, have been synthesised that incorporate the C1-OMe substituent present in the natural product. Electrophysiology experiments using Xenopus oocytes expressing nicotinic acetylcholine receptors (nAChRs) were conducted on these analogues and a related tricyclic analogue 2. The most potent compound, 2,(More)
Alzheimer's disease (AD) is caused by the accumulation of β-amyloid protein (Aβ) in the brain. The aggregation of β-amyloid protein to higher molecular weight fibrillar forms is also considered to be an important step in the pathogenesis of the disease. The memory problems associated with AD are likely to be caused by changes in synaptic plasticity. Recent(More)
