| Description | (–)-Lobeline is an alkaloid that has been found in Lobelia and has diverse biological activities. It binds to nicotinic acetylcholine receptors (nAChRs) in rat brain homogenates (Ki = 4 nM) and has antinociceptive effects in the tail-flick assay in mice. (–)-Lobeline (0.3 and 0.9 mg/kg) reduces the number of errors in a repeated acquisition procedure in the radial arm maze in rats. It also decreases immobility time in the forced swim test and feeding latency in the novelty suppressed feeding test, indicating antidepressant-like activity, in mice when administered at doses of 1 and 4 mg/kg. | | Chemical Properties | White to Off-White Solid | | Uses | A neuronal nicotinic acetylcholine receptor agonist. A CNS stimulant. | | Uses | A neuronal nicotinic acetylcholine receptor agonist. A respiratory stimulant | | Biological Activity | High affinity nicotinic receptor ligand, with a K i value of 4.4 nM in rat brain. | | in vitro | clastogenicity of lobeline and possible interactions between lobeline and ethyl alcohol were investigated in a mutagen-sensitivity assay on cultures of human lymphoblastoid cell lines. lobeline alone was not clastogenic, but there was a marked increase in genetic damage resulting from a coclastogenic interaction between lobeline and ethyl alcohol. [5] | | in vivo | male c57bl/6j mice were individually housed and acclimatized to 10% alcohol. lobeline is a partial nicotinic agonist that attenuates alcohol consumption and preference in male c57bl/6j mice. [3] cf-1 male mice received an intraperitoneal injection of lobeline (5 or 10mg/kg). lobeline did not show genotoxic or mutagenic effects and did not increase the ethanol-induced genotoxic effects in blood. lobeline also protected blood cells against oxidative damage induced by hydrogen peroxide.
