Rivanicline hemioxalate (RJR-2403 hemioxalate; (E)-Metanicotine hemioxalate) 是神经元烟碱受体 (neuronal nicotinic receptor) 激动剂，对 α4β2 亚型有高度选择性，K_i 为 26 nM，而对 α7 受体的 K_i 则为3.6 μM。

Rivanicline hemioxalate (RJR-2403 hemioxalate; (E)-Metanicotine hemioxalate) is a neuronal nicotinic receptor agonist, showing high selectivity for the α4β2 subtype (K i =26 nM); > 1,000 fold selectivity than α7 receptors(K i = 3.6 μM). IC50 value: 26 nM [1] Target: α4β2 nAChR in vitro: At concentrations up to 1 mM, Rivanicline does not significantly activate nAChRs in PC12 cells, muscle type nAChRs or muscarinic receptors. Dose-response curves for agonist-induced ileum contraction indicate that Rivanicline is less than one-tenth as potent as nicotine with greatly reduced efficacy. Rivanicline does not antagonize nicotine-stimulated muscle or ganglionic nAChR function (IC50 > 1 mM). Chronic exposure of M10 cells to Rivanicline (10 microM) results in an up-regulation of high-affinity nAChRs phenomenologically similar to that seen with nicotine
