Viltolarsen sodium  (Synonyms: NS-065/NCNP-01 sodium)

Viltolarsen (NS-065/NCNP-01) sodium is a phosphorodiamidate morpholino antisense oligonucleotide. Viltolarsen sodium binds to exon 53 of the dystrophin mRNA precursor and restores the amino acid open-reading frame by skipping exon 53, resulting in the production of a shortened dystrophin protein that contains essential functional portions. Viltolarsen sodium has the potential for Duchenne muscular dystrophy (DMD) research^[1][2].

Viltolarsen (NS-065/NCNP-01; 2 days) sodium induces exon 53 skipping in cells from a DMD model with a deletion of exons 45-52 with an EC₅₀ value of 0.63 μM and in cells with a deletion of exons 48-52 with an EC₅₀ value of 2.3 μM^[2].
Viltolarsen (10 μM; 3 days) sodium causes the dystrophin protein expression in cells from a DMD model^[2].
