Myosmine, a specific tobacco alkaloid in nuts and nut products, has low affinity for a4b2 nicotinic acetylcholinergic receptors (nAChR) with a Ki of 3300 nM[1][2].

Name	3-(3,4-dihydro-2H-pyrrol-5-yl)pyridine
Synonyms	Prestwick_202 3-(4,5-dihydro-3H-pyrrol-2-yl)-pyridine Pyridine, 3-(1-pyrrolin-2-yl)- dehydronornicotine 3-(3,4-Dihydro-2H-pyrrol-5-yl)pyridine Pyridine, 3-(3,4-dihydro-2H-pyrrol-5-yl)- MFCD00052019 3-(1-Pyrrolin-2-yl)pyridine Myosmine Pyridine,3-(3,4-dihydro-2H-pyrrol-5-yl)

Description	Myosmine, a specific tobacco alkaloid in nuts and nut products, has low affinity for a4b2 nicotinic acetylcholinergic receptors (nAChR) with a Ki of 3300 nM[1][2].
Related Catalog	Signaling Pathways >> Membrane Transporter/Ion Channel >> nAChR Signaling Pathways >> Neuronal Signaling >> nAChR Research Areas >> Metabolic Disease
Target	Ki: 3300 nM (a4b2 nAChR) and >10 µM (AT1)[1]
In Vitro	Myosmine is easily nitrosated, yielding 4-hydroxy-1-(3-pyridyl)-1-butanone (HPB) and the esophageal tobacco carcinogen N'-nitrosonornicotine[2].
In Vivo	Myosmine (0.001, 0.005, 0.5, and 50 micromol/kg; oral; in Wistar rats) causes a higher percentage of the radioactivity excreted in urine (86.2% and 88.9%) at the two lower doses (0.001 and 0.005 micromol/kg),as compared with the higher doses (0.5 and 50 micromol/kg), where only 77.8% and 75.4% of the dose is found in urine[2].
