PLoS ONE 2013, 8 (12) , e82726. … WebJan 1, 1997 · The agonist profile observed in hα7 also differs from that reported for its rat homolog (Seguela et al. , 1993). Human α4β2 and hα4β4 nAChRs were more sensitive to dihydro-β-erythroidine than d-tubocurarine, whereas hα7 and hα3β4 were more sensitive to d-tubocurarine than dihydro-β-erythroidine.

DHβE is used both in vitro and in vivo for its ability to block α4β2 nAChRs. This system was studied by three molecular dynamics simulations with a combined simulation time of 2.6 μs. dr katie keck ophthalmology richland

Competitive nicotinic acetylcholine receptor antagonist with moderate selectivity for the neuronal α4 receptor subunit ... 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. coherent labmax touch pro
