ProTx II;
ProTx II 是 Nav1.7 钠通道的选择性阻滞剂，IC50 值为 0.3 nM，对 Nav1. 7的选择性是其他钠通道亚型的至少 100 倍。ProTx-II 通过降低通道电导和将激活的电压转移到更多的正电位来抑制钠离子通道，并阻止伤害感受器中动作电位的传播。

| 生物活性 |
ProTx II is a selective blocker of Nav1.7 sodium channels with an IC50 of 0.3 nM, and is at least 100-fold selective for Nav1.7 over other sodium channel subtypes. ProTx-II inhibits sodium channels by decreasing channel conductance and shifting activation to more positive potentials and blocks action potential propagation in nociceptors[1][2]. |
