Methamphetamine-like discriminative-stimulus effects of nicotinic agonists. [PDF]

open access: yesJ Pharmacol Exp Ther, 2014
Nicotine was recently shown to engender d-methamphetamine (MA)-like discriminative-stimulus effects in rats, which may be indicative of shared psychomotor stimulant properties. To further investigate such overlapping discriminative-stimulus effects, nicotinic agonists varying in efficacy and selectivity were studied in squirrel monkeys that ...

Nicotine receptor partial agonists for smoking cessation [PDF]

open access: yesSao Paulo Medical Journal, 2007
Nicotine receptor partial agonists may help people to stop smoking by a combination of maintaining moderate levels of dopamine to counteract withdrawal symptoms (acting as an agonist) and reducing smoking satisfaction (acting as an antagonist). Varenicline was developed as a nicotine receptor partial agonist from cytisine, a drug widely used in central

Nicotine receptor partial agonists for smoking cessation

open access: yesCochrane Database of Systematic Reviews, 2023
Nicotine receptor partial agonists may help people to stop smoking by a combination of maintaining moderate levels of dopamine to counteract withdrawal symptoms (acting as an agonist) and reducing smoking satisfaction (acting as an antagonist). This is an update of a Cochrane Review first published in 2007.To assess the effectiveness of nicotine ...

Cholinergic modulation of dopamine overflow in the rat neostriatum: A fast cyclic voltammetric study in vitro [PDF]

open access: yes, 1994
Stimulus-evoked dopamine overflow in rat neostriatal slices was determined using fast cyclic voltammetry. The dopamine efflux induced by intrastriatal stimulation increased with stimulus intensity and was found to be enhanced by more than 100% upon ...

Neonicotinoids disrupt memory, circadian behaviour and sleep

open access: yesScientific Reports, 2021
Globally, neonicotinoids are the most used insecticides, despite their well-documented sub-lethal effects on beneficial insects. Neonicotinoids are nicotinic acetylcholine receptor agonists.

Advances in small molecule selective ligands for heteromeric nicotinic acetylcholine receptors

open access: yesPharmacological Research, 2023
The study of nicotinic acetylcholine receptors (nAChRs) has significantly progressed in the last decade, due to a) the improved techniques available for structural studies; b) the identification of ligands interacting at orthosteric and allosteric ...
