BMC Neuroscience, 2018 Background The treatment of Parkinson’s disease is often complicated by levodopa-induced dyskinesia (LID). Nicotinic acetylcholine receptor agonists can alleviate LID in animal models but may be less effective in conditions of severe dopaminergic ...

Suppression of methamphetamine-seeking behavior by nicotinic agonists [PDF]
Proceedings of the National Academy of Sciences, 2006 To understand the mechanism of methamphetamine (MAP) craving from the viewpoint of nicotinic acetylcholinergic transmission, we examined the responsible site of the brain for anticraving effects produced by nicotinic agonists by using a MAP self-administration paradigm in rats.

Neural signatures of cognitive flexibility and reward sensitivity following nicotinic receptor stimulation in dependent smokers : a randomized trial [PDF]
, 2017 IMPORTANCE Withdrawal from nicotine is an important contributor to smoking relapse. Understanding how reward-based decision making is affected by abstinence and by pharmacotherapies such as nicotine replacement therapy and varenicline tartrate may aid ...

Developmental sex differences in nicotinic currents of prefrontal layer VI neurons in mice and rats.
PLoS ONE, 2010 BackgroundThere is a large sex difference in the prevalence of attention deficit disorder; yet, relatively little is known about sex differences in the development of prefrontal attention circuitry.

Cyclic nucleotide-gated channels: structural basis of ligand efficacy and allosteric modulation [PDF]
, 1997 Most working proteins, including metabolic enzymes, transcription regulators, and membrane receptors, transporters, and ion channels, share the property of allosteric coupling. The term 'allosteric' means that these proteins mediate indirect interactions

The Nicotinic Agonist Cytisine: The Role of the NH···N Interaction
The Journal of Physical Chemistry Letters, 2022 We report a detailed structural study of cytisine, an alkaloid used to help with smoking cessation, looking forward to unveiling its role as a nicotinic agonist. High-resolution rotational spectroscopy has allowed us to characterize two different conformers exhibiting axial and equatorial arrangements of the piperidinic NH group.

Aspectos toxicológicos e químicos da Anatoxina-a e seus análogos
Química Nova, 2006 Anatoxin-a and its analogues are azabicyclic alkaloids that represent one of the most powerful nicotinic agonists known for the nicotinic acetylcholine receptor (nAChR). Because of this potent mechanism of action, anatoxin-a and its derivatives represent

Nicotinic alpha 7 receptor agonists EVP-6124 and BMS-933043, attenuate scopolamine-induced deficits in visuo-spatial paired associates learning. [PDF]
PLoS ONE, 2017 Agonists at the nicotinic acetylcholine alpha 7 receptor (nAChR α7) subtype have the potential to treat cognitive deficits in patients with Alzheimer's disease (AD) or schizophrenia.
