Product Data:
Biological target: NS3861 fumarate is an agonist of nicotinic acetylcholine receptors (nAChRs) and binds with high affinity to heteromeric α3β4 nAChR.
In vitro activity: The novel compound NS3861 and cytisine are agonists of nicotinic acetylcholine receptors (nAChRs) and both bind with high affinity to heteromeric α3β4 and α4β2 nAChRs. The maximal efficacy of NS3861 appeared solely dependent on the nature of the ligand-binding domain, whereas efficacy of cytisine was additionally affected by the nature of the β-subunit transmembrane domain. Reference: J Biol Chem. 2013 Jan 25;288(4):2559-70. https://pubmed.ncbi.nlm.nih.gov/23229547/
In vivo activity: The present study examined whether the increased sensitivity to nicotine could be observed in single enteric neurons after long-term morphine exposure, determined the subunits in mouse enteric neurons, and examined the effect of nicotine in reversing opioid-induced constipation. NS3861, a partial agonist at α3β4 nAChR, enhanced fecal pellet expulsion in a dose-dependent manner in mice that received long-term, but not short-term, morphine treatment.
