Altinicline (SIB-1508Y, SIB-1765F) is a drug which acts as an agonist at neural nicotinic acetylcholine receptors with high selectivity for the α4β2 subtype. It stimulates release of dopamine and acetylcholine in the brain in both rodent and primate models, and progressed as far as Phase II clinical trials for Parkinson's disease, where "no antiparkinsonian or cognitive-enhancing effects were demonstrated", although its current status is unclear.

Sample Use Guides

10 mg daily
Route of Administration: Oral
[3H]-DA uptake in rat striatal synaptosomes was conducted as described before: briefly, 100 μl of crude P2 synaptosomal fraction were preincubated in the presence of varying concentrations of test compounds (SIB-1765F) for 10 min before the addition of [3H]-DA final concentration of 10 nM
