DC73683 LTGO-33 LTGO-33 is a potent, selective inhibitor of voltage-gated sodium channel NaV1.8 with IC50 of 44 nM (hNaV1.8), 600-fold selectivity against NaV1.1-NaV1.7 and NaV1.9.
DC70805 SSCI-2 SSCI-2 is a highly potent, selective NaV1.7 inhibitor with IC50 of 9 and 17 nM on human and rhesus Nav1.7 channels, respectively.SSCI-2 showed robust selectivity over other human and rhesus Nav channel paralogs, with the exception of Nav1.2 channels (IC50 183 nM for hNaV1.2), shows no other channels and receptors in 114 enzymatic, radioligand binding, and cellular assays.SSCI-2 also exhibits high potency in manual patch clamp experiments (IC50=24/62 nM for huma/rhesus Nav1.7 channels).SSCI-2 inhibits withdrawal responses to noxious heat in rhesus monkeys.
DC70247 BI 1265162 BI 1265162 is a potent ENaC inhibitor, inhibits Na+ transport with IC50 3 nM and 8 nM in M1 and NCI-H441 cells, respectively.BI 1265162 dose-dependently inhibited Na+ transport and decreased water resorption in cell line models.BI 1265162 reduced liquid absorption in rat lungs and increased MCC in sheep, with no effects on renal function in the animal models.BI 1265162 alone and in combination with CF transmembrane conductance regulator (CFTR) modulators decreased water transport and increased MCC in both normal and CF airway human epithelial models.
DC48532 Tocainide Tocainide hydrochloride is an orally activesodium channel blocker, it blocks the sodium channels in the pain-producing foci in the nerve membranes. Tocainide hydrochloride is a primary amine analog of lidocaine, can be used for the treatment of tinnitus.
DC48204 QX-222 chloride QX-222 chloride, a trimethyl analogue of Lignocaine, is a potent Na+ channel blocker.
DC47939 NBI-921352 NBI921352 is a Nav1.6 inhibitor with an IC50 value of 3.765 μM.
DC40101 Phenamil methanesulfonate Phenamil methanesulfonate, an analog of Amiloride, is a more potent and less reversible epithelial sodium channel (ENaC) blocker with an IC50 of 400 nM. Phenamil methanesulfonate is also a competive inhibitor of TRPP3 and inhibits TRPP3-mediated Ca2+ transport with an IC50 of 140 nM in a Ca2+ uptake assay. Phenamil methanesulfonate is an intriguing small molecule to promote bone repair by strongly activating BMP signaling pathway. Phenamil methanesulfonate is used for the research of cystic fibrosis lung disease.
DC28765 Ethacizine hydrochloride Ethacizine hydrochloride (Ethacizin; NIK-244) is a Class Ic antiarrhythmic agent, which means it is part of a group of drugs that primarily act by blocking sodium channels in the heart. This class of antiarrhythmic agents is known for their potent effects on slowing conduction in the heart, particularly in the atria, ventricles, and the His-Purkinje system.
DC28483 Nav1.1 activator 1 Nav1.1 activator 1 (compound 4), a highly potent Nav1.1 activator with BBB penetration, increases decay time constant (tau) of Nav1.1 currents at 0.03 μM along with significant selectivity against Nav1.2, Nav1.5, and Nav1.6.
DC7287 Ralfinamide Sodium channel blocker. Suppresses tetrodotoxin (TTX)-resistant Na+ currents approximately twice as selectively as TTX-sensitive currents. Antinociceptive; displays analgesic effects in animal models of inflammatory and neuropathic pain.
