HAINANTOXIN-III | Product ID | L8431-100UG |
| Name | HAINANTOXIN-III |
| Molecular formula | C154H228N44O45S6 |
| Description |
A 33 amino-acids peptide with 3 disulfide bridges , synthetic, initially isolated from the venom of the Chinese black earth tiger spider Haplopelma hainanus, also known as Cyriopagopus hainanus. |
| Biological activity | Hainantoxin-III is a sSelective antagonist of neuronal tetrodotoxin (TTX)-sensitive voltage-gated sodium channels (IC50=1270 nM on Nav1.1/SCN1A, 270 nM on Nav1.2/SCN2A, 491 nM on Nav1.3/SCN3A and 232 nM on Nav1.7/SCN9A). It also suppresses Nav1.7 current amplitude without significantly altering the activation, inactivation, and repriming kinetics. It has no activity on Nav1.4, Nav1.5, Nav1.8 and Nav1.9 sodium and calcium currents. |
