SMILES: [Tofersen (sodium)]
Biological Activity: Tofersen (BIIB067) sodium is an antisense oligonucleotide and SOD1 mRNA inhibitor with an IC50 of 320 pM. Tofersen sodium mediates RNase H-dependent degradation of SOD1 mRNA to reduce SOD1 protein levels in cerebrospinal fluid and serum. Tofersen sodium downregulates cerebrospinal fluid neurofilament light chain, neurofilament heavy chain, amyloid-beta 1-40, amyloid-beta 1-42, neuropeptide Y, ubiquitin C-terminal hydrolase L1, neuropentraxins 1, 2, R, corticotropin-releasing hormone, IL-15, and serum neurofilament light chain, neurofilament heavy chain. Tofersen sodium can be used for the research of superoxide dismutase 1-associated amyotrophic lateral sclerosis[1][2][3][4][5][6][7][8][9].
