DS-1971a Chemical Properties,Usage,Production

Uses

DS-1971a is a potent, selective, and orally active NaV1.7 inhibitor, with IC50s of 22.8 and 59.4 nM for hNaV1.7 and mNaV1.7, respectively. DS-1971a exerts analgesic effects[1].

in vivo

DS-1971a exhibits a favorable toxicological profile[1].
DS-1971a (0.1-1 mg/kg; p.o.) shows mitigated thermal hyperalgesia in a dose-dependent manner in partial sciatic nerve ligation (PSL) mice[1].

Animal Model:Male Slc:ddY mice (PSL model)[1]
Dosage:0.1, 0.3, and 1 mg/kg
Administration:P.o.
Result:A significant dose-dependent suppression of thermal hyperalgesiain 0.3 and 1 mg/kg administered groups. The ED50 of DS-1971a at the peak efficacy was 0.32 mg/kg.

IC 50

hNav1.7: 22.8 nM (IC50); mNav1.7: 59.4 nM (IC50)
