Rivanicline
Rivanicline (TC-2403, RJR-2403, (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,〔Jang J, Sin KS, Park H. Synthesis of (+/-)-methyl-(1-aryl-4-pyridin-3-yl-but-3-enyl)-amines. ''Archives of Pharmacal Research''. 2001 Dec;24(6):503-7. PMID 11794523〕〔Sapronov NS, Fedotova YO, Kuznetsova NN. Antiamnestic effect of alpha7-nicotinic receptor agonist RJR-2403 in middle-aged ovariectomized rats with Alzheimer type dementia. ''Bulletin of Experimental Biology and Medicine''. 2006 Dec;142(6):700-2. PMID 17603674〕 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.〔Spoettl T, Paetzel C, Herfarth H, Bencherif M, Schoelmerich J, Greinwald R, Gatto GJ, Rogler G. (E)-metanicotine hemigalactarate (TC-2403-12) inhibits IL-8 production in cells of the inflamed mucosa. ''International Journal of Colorectal Disease''. 2007 Mar;22(3):303-12. PMID 16715250〕 Rivanicline also has stimulant and analgesic actions which are thought to be mediated through stimulation of noradrenaline release,〔Li X, Eisenach JC. Nicotinic acetylcholine receptor regulation of spinal norepinephrine release. ''Anesthesiology''. 2002 Jun;96(6):1450-6. PMID 12170059〕 and so it could potentially also have other applications.
