nav1.4 channel

µ-Conotoxin-CnIIIC acetate 是一种高效的 NaV1.4 钠通道拮抗剂，是由22个氨基酸组成的芋螺肽，可用于肌肉松弛和缓解疼痛。

Lu AE98134, an activator of voltage-gated sodium channels, acts as a partly selective Nav1.1 channels positive modulator. Lu AE98134 also increases the activity of Nav1.2 and Nav1.5 channels but not of Nav1.4, Nav1.6 and Nav1.7 channels. Lu AE98134 can be used to analyze pathophysiological functions of the Nav1.1 channel in various central nervous system diseases, including cognitive restoring in schizophrenia, et al[1].

ICA-121431 (2,2-Diphenyl-N-[4-(thiazol-2-ylsulfamoyl) 是强效的、广谱的电压门控钠通道阻滞剂，对人 Nav1.1 和 Nav1.3 亚型具有等效选择性，IC50分别为 13 nM 和 23 nM。它对Nav1.2 的抑制作用较弱，IC50为240 nM，对 Nav1.4、Nav1.6、抗TTX 的人 Nav1.5、Nav1.8 通道表现出大于 1000 倍的选择性，IC50>10 μM。

μ-Conotoxin-CnIIIC为具有22个氨基酸残基的芋螺肽，源自(Conus consors)。它作为NaV1.4通道的阻断剂，展现出强效及长效性质。μ-Conotoxin-CnIIIC还表现出镇痛、麻醉和肌肉松弛的生物学功能。

μ-Conotoxin GIIIB为含22个氨基酸残基的多肽，源自鱼食性圆锥蜗牛Conus geographus的毒液。该化合物作用于NaV1.4通道，具有抑制功能，能够阻止肌肉细胞收缩。

GrTx1是一种从Grammostola rosea蜘蛛的毒液中分离的肽毒素。该分子能够阻断sodium channel，对Nav1.1，Nav1.2，Nav1.3，Nav1.4，Nav1.6和Nav1.7具有不同的抑制作用，IC50值分别为0.63 µM, 0.23 µM, 0.77 µM, 1.29 µM, 0.63 µM和0.37 µM，适用于神经疾病的研究领域。

Ceratotoxin-1 (CcoTx1)为电压门控钠通道亚型的抑制剂，特别是对Nav1.1 β1、Nav1.2 β1、Nav1.4 β1和Nav1.5 β1具有不同程度的抑制效果，其IC50值分别为523 nM、3 nM、888 nM和323 nM。此外，Ceratotoxin-1对Nav1.8 β1亦有抑制作用。

μ-Conotoxin BuIIIC 是一种针对Nav1.4离子通道的有效抑制剂。

Potent rat Nav1.7, human Nav1.4 and rat Nav1.6 channel activator (EC50 values are 7, 10 and 47 nM, respectively). Exhibits minimal activation at mammalian Nav1.2, Nav1.3 and Nav1.5 (EC50 values >3 μM). Inhibits fast inactivation on all channels. Increases

Selective NaV1.7 channel blocker. Preferentially inhibits neuronal NaV1.7, 1.2 and 1.3 (IC50 values are 26, 150 and 338 nM respectively), compared to muscle subtypes NaV1.4 and 1.5 (IC50 = >10 μM). Inhibits the channel by binding at the neurotoxin recepto
