nav1.7/nav1.8

DSP-2230 is a selective blocker of Nav1.7/Nav1.8.

(R)-DSP-2230 is the R-isomer of DSP-2230. DSP-2230 is a selective blocker of Nav1.7/Nav1.8.

E0199 is an innovative and potent KV7/NaV dual-target modulator that activates KV7 potassium channels, including KV7.2/7.3 (EC50 = 12.78 nM), KV7.2 (EC50 = 0.50 μM), and KV7.5 (EC50 = 27.14 nM), while inhibiting NaV1.7 (IC50 = 0.52 μM), NaV1.8 (IC50 = 0.24 μM), and NaV1.9 (IC50 = 0.16 μM) sodium channels. In a mouse model of chronic constriction injury (CCI) to the sciatic nerve, E0199 demonstrated potent analgesic effects without significant impact on cardiac and skeletal muscle ion channels. E0199 is applicable in studies related to neuropathic pain (NP).

TC-N 1752 is an orally active inhibitor of Nav1.7 channel with IC50 of 0.17 μM. TC-N 1752 shows analgesic activities.

4,9-Anhydrotetrodotoxin (4,9-anhydro-TTX) is a derivative of TTX that selectively blocks inward sodium current through Nav1.6 voltage-activated sodium channels (IC50 = 7.8 nM in Xenopus oocytes). [1][2][3] It demonstrates IC50 values of 1.3, 0.34, 0.99, 78.5, 1.3, and >30 &#181M for Nav1.2, Nav1.3, Nav1.4, Nav1.5, Nav1.7, and Nav1.8, respectively.[1]

ABBV-318 can be used as small molecule Nav1.7/Nav1.8 blockers for the treatment of pain, with IC50 values of 2.8 μM for hNav1.7 and 3.8 μM for hNav1.8. ABBV-318 can be used to study pain-related disorders.

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.

Heteropodatoxin-1 (HpTx1), a spider peptide toxin, inhibits Kv4.2 and Nav1.7 currents while activating Nav1.9 channels, with no effect on Nav1.8 channels [1].

LTGO-33 is a species-specific inhibitor of the voltage-gated sodium channel NaV1.8, inhibiting NaV1.8, NaV1.1-NaV1.7, and NaV1.9.LTGO-33 inhibits wild-type and multiple NaV1.8 variants associated with human pain disorders and can be used for the study of pain.hBChE-IN-2 is a low affinity Nurr1 agonist.

3'-Methoxydaidzein is a dual isoflavone and Sodium Channel inhibitor. 3'-Methoxydaidzein inhibited NaV1.7, NaV1.8 and NaV1.3 with IC50 of 181 nM, 397 nM and 505 nM, respectively. 3'-Methoxydaidzein was specific for collagen-induced platelet aggregation with IC50 values of 12.3 and 61.5µM, respectively. 3'-Methoxydaidzein acts as an analgesic by inhibiting voltage-gated sodium channels. 3'-Methoxydaidzein showed antioxidant activity and antiplatelet aggregation activity.
