Viltolarsen (NS-065/NCNP-01) is a phosphorodiamidate morpholino antisense oligonucleotide. Viltolarsen 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 has the potential for Duchenne muscular dystrophy (DMD) research.

Description

Viltolarsen (NS-065/NCNP-01) is a phosphorodiamidate morpholino antisense oligonucleotide. Viltolarsen 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 has the potential for Duchenne muscular dystrophy (DMD) research[1][2].

In Vitro

Viltolarsen (NS-065/NCNP-01; 2 days) 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) causes the dystrophin protein expression in cells from a DMD model[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
