Is active on muscle nAChR (IC(50)=113 nM on adult subtype (alpha-1-beta-1-gamma-delta/CHRNA1-CHRNB1-CHRNG-CHRND) and IC(50)=142 nM on fetal subtype (alpha-1-beta-1-delta-epsilon/CHRNA1-CHRNB1-CHRND-CHRNE)) (PubMed:35357806, PubMed:9174364). On mice muscle receptors, its higher affinity site is the alpha/delta nAChR subunit interface (PubMed:9174364). On Torpedo receptors, it does not distinguish between alpha/delta and alpha/gamma acetylcholine-binding sites (PubMed:9174364). In vivo, causes paralysis followed by death when injected into goldfish (PubMed:3196703). In contrast, has no effect on mice, when similar doses are intraperitoneally or intracerebrally injected (PubMed:3196703).<ref>PMID:3196703</ref> <ref>PMID:35357806</ref> <ref>PMID:9174364</ref> |
