Background

RJR-2403 Description:
Ki: RJR-2403 compound binds with high affinity to [3H]nicotine binding sites in rat brain (Ki 526 nM) but possesses weak affinity (36 mM) for the 125I-labeled a-bungarotoxin-sensitive nAChR subtype [1].
RJR-2403 (TC-2403, Rivanicline, (E)-metanicotine) is a drug which acts as a partial agonist at neural nicotinic acetylcholine receptors. It is subtype-selective, binding primarily to the α4β2 subtype. It has nootropic effects and was originally developed as a potential treatment for Alzheimer's disease, but a second action that was subsequently found was that it inhibits the production of Interleukin-8 and thus produces an antiinflammatory effect, and so it has also been developed as a potential treatment for ulcerative colitis. RJR-2403 also has stimulant and analgesic actions which are thought to be mediated through stimulation of noradrenaline release, and so it could potentially also have other applications.
In vitro: Prevous in vitro results suggest that RJR-2403 interacts with higher potency at CNS nAChR sub-types than at muscle, ganglionic or enteric nAChRs and has higher selectivity for CNS vs. muscle or ganglionic nAChRs than does nicotine. [2].
In vivo: The data from an in vivo study demonstrate the efficacy of oral RJR 2403 in improving cognitive performance and the long duration of action of RJR 2403 in young adult rats. In contrast, no significant memory improvement was seen in aged rats aged (24–26 months old) after RJR 2403 administration. The inability of RJR 2403 to enhanced cognitive functions in aged rats might be related to the decrease in the number of α4β2 nicotinic receptors, which occurs with age. A similar decreased responsiveness in aged rats has been seen with nicotine. The persistence of action of RJR 2403 provides additional promise for its potential as a treatment for cognitive dysfunction [3].
Clinical trial: Up to now, RJR-2403 is still in the preclinical development stage.
