 Use of Nelonicline citrate


Nelonicline (ABT-126) citrate is an orally active and selective α7 nicotinic receptor agonist with high affinity to α7 nAChRs in human brain (Ki=12.3 nM). Nelonicline citrate is used for the research of shizophrenia and Alzheimer's disease[1][2][3].

Description Nelonicline (ABT-126) citrate is an orally active and selective α7 nicotinic receptor agonist with high affinity to α7 nAChRs in human brain (Ki=12.3 nM). Nelonicline citrate is used for the research of shizophrenia and Alzheimer's disease[1][2][3].
Related Catalog
In Vitro Nelonicline citrate is an agonist that binds with high affinity to α7 nAChRs in human brain (Ki= 12.3 nM) and activates currents in Xenopus oocytes expressing recombinant human α7 nAChRs (EC50=2 μM; intrinsic activity of 74% relative to acetylcholine). Nelonicline citrate does bind to α3β4* nAChRs in human IMR-32 neuroblastoma cells (Ki=60 nM), but has only 12% efficacy at 100,000 nM in a calcium flux assay in these cell. Like some other α7 nAChR agonists, Nelonicline citrate is also a 5-HT3 receptor antagonist, but it has >10-fold lower affinity for this receptor than for α7 nAChRs (Ki of 140 nM)[1].
