SCYLLATOXIN [R7]- | Product ID | L8224-100UG |
| Name | SCYLLATOXIN [R7]- |
| Molecular formula | |
| Description |
It is an inhibitor of the binding of [125I]-apamin to rat brain synaptosomes and a specific neurotoxicity in mice. A 31-amino acid peptide with 3 disulfide bonds , synthetic from the Leiurotoxin I, isolated from Leiurus quinquestriatus hebraeus scorpion venom |
| Biological activity | [R7]-Lei-OH inhibited binding of [125I]-apamin to its receptor in pharmacological experiments using rat brain synaptosomes and showed increased affinities when compared to natural toxins Lei-NH2 and Lei-OH. Experimental dose: EC50 at 0.08-0.1 nM |
