ProTx-III
ProTx-III is a selective and potent inhibitor of voltage-gated sodium channel Nav1.7, with an IC50 of 2.1 nM. ProTx-III is a spider venom peptide isolated from the venom of the Peruvian green velvet tarantella. ProTx-III has a typical inhibitor cystine knot motif (ICK). ProTx-III is able to reverse the pain response. ProTx-III can be used to study diseases such as chronic pain, epilepsy, and arrhythmia.

Nav1.7 2.1 nM (IC50) |
ProTx-III in native, recombinant and synthetic C-terminal acid and amide forms inhibit hNaV1.7 with IC50s of 2.1, 9.5, 11.5 and 2.5 nM, respectively[1].
.
ProTx-III inhibits hNav1.7 without significantly altering the voltage dependence of activation or inactivation[1].

Animal Model:OD1-induced mouse model of pain(300Nm; intraplantar injection)[1]
-
Dosage:100 nM, 300 nM, 1μM
-
Administration:intraplantar injection
-
Result:Showed at 1 μM (40 pmoles in a 40 μl injection) and 300 nM (12 pmoles in a 40 μl injection) significantly reduced spontaneous pain behaviour in a concentration dependent manner and this reduction in pain behaviour persisted for 25 min after injection of the highest concentration.
