| | Dihydro-β-erythroidine hydrobromide Usage And Synthesis |
| Uses | Dihydro-β-erythroidine is an alkaloid isolated from the seeds of erythrina and a competitive antagonist at the nicotinic acetylcholine receptor (nAChR). | | Definition | ChEBI: Dihydro-beta-erythroidine hydrobromide is a member of indoles. | | Biological Activity | Competitive nicotinic acetylcholine receptor antagonist with moderate selectivity for the neuronal α 4 receptor subunit (IC 50 values are 0.19 and 0.37 μ M for α 4 β 4 and α 4 β 2 receptors respectively). Antagonizes behavioral effects of nicotine in vivo . | | in vitro | dhβe has been shown to be a purely competitive antagonist of the neuronal nicotinic receptor [1]. | | in vivo | dhβe is able to block some of the central actions of nicotine after systemic and intrathecal administration. the mechanism of blockade is different from that of mecamylamine, a classical ganglionic antagonist, and may involve a direct action of dhβe on nicotine receptor [2]. | | IC 50 | 1.3 μm for α2β2, 2.3 μm for α2β4, 0.41 μm for α3β2, 23.1 μm for α3β4, 0.37 μm for α4β2, and 0.19 μm for α4β4 [1] | | storage | Desiccate at RT | | references | [1] harvey sc, maddox fn, luetje cw. multiple determinants of dihydro-beta-erythroidine sensitivity on rat neuronal nicotinic receptor alpha subunits. j neurochem. 1996 nov;67(5):1953-9.
