Sodium Channel Antagonist

Sodium Channel Antagonists (15):

Cat. No. Product Name Effect Purity
  • HY-A0082
    Diphenidol hydrochloride
    		Antagonist 99.95%
    Diphenidol hydrochloride (Difenidol hydrochloride) is a non-selective muscarinic M1-M4 receptor antagonist, has anti-arrhythmic activity. Diphenidol hydrochloride is also a potent non-specific blocker of voltage-gated ion channels (Na+, K+, and Ca2+) in neuronal cells. Diphenidol hydrochloride can be used in the study of antivertigo and antinausea.
  • HY-105283
    PF 04531083
    		Antagonist 98.96%
    PF 04531083 is a selective NaV1.8 blocker, and used for the research of neuropathic/inflammatory pain.
  • HY-B1657A
    Fosphenytoin disodium
    		Antagonist 99.81%
    Fosphenytoin sodium is a phenytoin proagent with similar anticonvulsant properties. Its main mechanism is to block frequency-dependent, use-dependent and voltage-dependent neuronal sodium channels, and therefore limit repetitive firing of action potentials.
  • HY-N3990
    Hardwickiic acid
    		Antagonist ≥98.0%
    Hardwickiic acid ((-)-Hardwikiic acid) is an antinociceptive compound that blocks Tetrodotoxin-sensitive voltage-dependent sodium channels. Hardwickiic acid shows insecticidal activity.
  • HY-108425
    AMG8379
    		Antagonist
    AMG8379 is a potent, orally active and selective sulfonamide antagonist of the voltage-gated sodium channel NaV1.7, with IC50s of 8.5 and 18.6 nM for hNaV1.7 and mNaV1.7, respectively. AMG8379 potently and reversibly blocks endogenous Tetrodotoxin (TTX)-sensitive sodium channels in dorsal root ganglia (DRG) neurons with an IC50 of 3.1 nM.
  • HY-108425B
    (Rac)-AMG8379
    		Antagonist
    (Rac)-AMG8379 ((Rac)-AMG8380) is a racemate of AMG8379. AMG8379 is a potent, orally active and selective sulfonamide antagonist of NaV1.7, with IC50s of 8.5 and 18.6 nM for hNaV1.7 and mNaV1.7, respectively .
  • HY-P5184
    Hainantoxin-IV
    		Antagonist
    Hainantoxin-IV is a specific antagonist of Sodium Channel, targeting to tetrodotoxin-sensitive (TTX-S) voltage-gated sodium channels. His28 and Lys32 are the key resiudes of Hainantoxin-IV for binding with target, while Hainantoxin-IV adopts an inhibitor cystine knot motif.
  • HY-107695
    Remacemide hydrochloride
    		Antagonist
    Remacemide hydrochloride (FPL 12924AA), a moderate inhibitor of the Na+ channel, is a weak uncompetitive NMDA receptor antagonist with IC50s of 68 μM and 76 μM for MK-801 binding and NMDA currents, respectively. Remacemide hydrochloride is an anticonvulsant agent.
  • HY-15082
    Irampanel
    		Antagonist
    Irampanel (BIIR 561) is an AMPA receptor and voltage-dependent sodium channel blocker. Irampanel inhibits kainate-induced currents in rat cortical neurons.
  • HY-108425A
    AMG8380
    		Antagonist
    AMG8380, an orally active and less active enantiomer of AMG8379, can serves as a negative control. AMG8380 inhibits human and mouse voltage-gated sodium channel NaV1.7 with IC50s of 0.907 and 0.387 μM, respectively. AMG8380 blocks Tetrodotoxin (TTX)-sensitive native channels with an IC50 of 2560 nM.
  • HY-B1657AS
    Fosphenytoin-d10 disodium
    		Antagonist
    Fosphenytoin-d10 (disodium) is deuterium labeled Fosphenytoin (disodium). Fosphenytoin sodium is a phenytoin proagent with similar anticonvulsant properties. Its main mechanism is to block frequency-dependent, use-dependent and voltage-dependent neuronal sodium channels, and therefore limit repetitive firing of action potentials.
  • HY-P1681
    GpTx-1
    		Antagonist
    GpTx-1 is a potent and selective NaV1.7 antagonist with an IC50 of 10 nM.
  • HY-P5180
    Hainantoxin-III
    		Antagonist
    Jingzhaotoxin-V is a peptide that inhibits potassium currents in Xenopus laevis oocytes with an IC50 value of 604.2 nM. Jingzhaotoxin-V also inhibits tetrodotoxin-resistant and tetrodotoxin-sensitive sodium currents in rat dorsal root ganglion neurons with IC50 values of 27.6 and 30.2 nM, respectively.
  • HY-A0270
    Diphenidol
    		Antagonist
    Diphenidol is a non-selective muscarinic M1-M4 receptor antagonist, has anti-arrhythmic activity. Diphenidol is also a potent non-specific blocker of voltage-gated ion channels (Na+, K+, and Ca2+) in neuronal cells. Diphenidol can be used in the study of antivertigo and antinausea.
