Compound class: Synthetic organic
Comment: Nusinersen (ISIS 396443) is an antisense oligo(ribo)nucleotide (ASO) which induces survival motor neuron (SMN) protein expression from SMN2 genes with the exon 7-skipping mutation [7].
Nusinersen was initially available for use as a designated orphan drug (by the US FDA and EMA), and was the first drug to be fully approved for the treatment of spinal muscular atrophy (SMA).

The sequence contains 2'-O-(2-methoxyethyl) (2'-MOE)-oligoribonucleotides to reduce nuclease degradation and enhance binding affinity towards the complementary RNA. The full sequence is [2'-O-(2-methoxyethyl)](3'-5')(P-thio)(mU-mC-A-mC-mU-mU-mU-mC-A-mU-A-A-mU-G-mC-mU-G-G) as detailed in the INN record for the agent. A full structural rendering using SMILES from Chemspider is available here (CSID:34983394). The sequence for nusinersen is claimed in patent WO2010148249A1 as SEQ ID NO: 1 [1].
