WebWith such a wide range of activities, d -tubocurarine is of limited utility. Dihydro-β-erythroidine (DHβE) is a plant-derived competitive antagonist of heteromeric nicotinic receptors. It is somewhat more effective at α4-and β2-containing receptors than at those containing α3 and much less effective at α7 nAChRs. Webβ-erythroidine have been isolated and structurally characterized from the methanolic extract of the stem bark of E. poeppigiana.
