Zotadirsen

Customer Review

Based on 1 Customer Validation

Zotadirsen is the core component of the AOC drug Delpacibart zotadirsen (AOC1044) (HY-177564), consisting of a phosphorodiamidate morpholino oligonucleotide (PMO) targeting exon 44 of the dystrophin gene and an SMCC linker (HY-42360). Upon conjugation with the anti-TfR1 antibody Delpacibart (HY-P990051), Zotadirsen exerts splicing regulatory activity and mediates exon skipping. Zotadirsen can be used in studies related to AOC synthesis.

Biological Activity

Description

In Vivo

Zotadirsen, which composes Delpacibart zotadirsen (AOC1044), can accumulate in muscle tissue to reach therapeutically effective concentrations^[1].
Zotadirsen, the active oligonucleotide component of Delpacibart zotadirsen (5–10 mg/kg), induces exon 44 skipping in a dose-dependent manner, elevates dystrophin expression in DMD44 subjects, reduces serum markers of muscle injury, and exhibits favorable safety and tolerability profiles^[2].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
