  • HY-P1681
    GpTx-1
    		Antagonist
    GpTx-1 is a peptide-based NaV1.7 sodium channel antagonist isolated from the venom of the Chilean spider Grammostola porter. GpTx-1 demonstrates potent inhibitory activity against the NaV1.7 channel with an IC50 value of 10 nM, while exhibiting excellent selectivity for NaV1.4 (IC50 = 0.301 μM) and NaV1.5 (IC50 = 4.20 μM), showing >20-fold and >950-fold selectivity respectively.
  • 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.
