Hainantoxin-III

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[1].
