PUROTOXIN-1 | Product ID | L8424-100UG |
| Name | PUROTOXIN-1 |
| Molecular formula | C155H248N50O48S8 |
| Description |
A 35 amino-acids peptide with 4 disulfide bridges , synthetic, initially isolated from the venom of a species of burrowing wolf spider from Central Asia, Geolycosa sp. |
| Biological activity | Purotoxin-1 (PT-1) inhibits selectively P2X3 receptor channels at a 100 nM concentration, making it the most potent and selective ligand for P2X3. Studies did not show any inhibitory effect of PT-1 on voltage-gated channels (potentials range tested from -100 to 20 mV), neither on TRPV1 (after activation with 500 nM capsaicin). Therapeutic interest : pain, as P2X3 receptors are known to be implicated in pain mechanisms. |
