nav1.5 channel

Sulcardine 2HCl is a multi-ion channel blocker with antiarrhythmic effects that blocks the properties of hERG and hNav1.5 channels and can be used to study atrial fibrillation and ventricular arrhythmias.

AZD 7009 is a novel antiarrhythmic compound that inhibits the sodium current of hNav1.5 in CHO K1 cells with an IC50 of 11 uM. AZD 7009 inhibited late sodium current in isolated rabbit atrial and ventricular myocytes, and prolonged E-4031-induced action potential duration, promoting early post-depolarization of Purkinye fibers (EADs).

AZD7507 is a CSF-1R inhibitor with an IC50 of 32 nM. AZD7507 has antitumor activity.

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

Lu AE98134, an activator of voltage-gated sodium channels, acts as a partly selective positive modulator of Nav1.1 channels and also increases the activity of Nav1.2 and Nav1.5 channels while not affecting 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) is a nanomolar potent small molecule Nav1.7 channel inhibitor with IC50 of 19 nM for rat Nav1.7, with little or no activity against human Nav1.5 or Nav1.7 channels.

Flecainide acetate (R-818) is a class Ic antiarrhythmic agent used to prevent and treat tachyarrhythmias (abnormally fast heart rhythms).

Phlo1a (μ-TrTx-Phlo1a), a 35-amino acid peptide toxin, demonstrates a weak inhibitory effect on Nav1.2 and Nav1.5 channels [1]. Meanwhile, Phlo1b acts as a selective inhibitor of the Nav1.7 channel.

F 15845 is a blocker of the persistent sodium current prevents consequences of hypoxia in rat femoral artery. F15845 has been shown to selectively inhibit the persistent sodium current of Nav1.5[1] exerting cardioprotective effects following ischemia. In vitro testing showed minimal effects of F15845 on other important ion channels of the heart, including major Ca2+ and K+ channels.[1] This characteristic is thought to account for the limited effect of F15845 to change other heart parameters such as basal cardiac function, hemodynamic functions and ventricular fibrillation. F15845 was also shown to exert improved effects when the membrane potential was depolarized,[1] by acting on the extracellular side of the channel.

Ceratotoxin-1 (CcoTx1) is a peptide toxin that functions as an inhibitor of various voltage-gated sodium channel subtypes. It selectively inhibits Nav1.1 β1, Nav1.2 β1, Nav1.4 β1, and Nav1.5 β1 with IC50 values of 523 nM, 3 nM, 888 nM, and 323 nM, respectively. Additionally, Ceratotoxin-1 is known to inhibit Nav1.8 β1 [1].

GS-462808 is a late sodium current inhibitor of the cardiac Nav1.5 channel. GS-462808 had lower brain penetration and serendipitously lower activity at the brain isoforms.
