Potent rat Nav1.7, human Nav1.4 and rat Nav1.6 channel activator (EC50 values are 7, 10 and 47 nM, respectively). Exhibits minimal activation at mammalian Nav1.2, Nav1.3 and Nav1.5 (EC50 values >3 μM). Inhibits fast inactivation on all channels. Increases
Tofersen (BIIB067) is an antisense oligonucleotide utilized to inhibit the synthesis of superoxide dismutase 1 (SOD1) protein by facilitating the degradation of SOD1 mRNA via the RNase H-dependent mechanism. This compound holds potential for amyotrophic lateral sclerosis (ALS) research.
