| Hazard Information | Back Directory | [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.
