Description

Exaluren (ELX-02; NB-124) disulfate is an synthetic eukaryotic ribosome-selective glycoside that induces read-through of nonsense mutations, resulting in normally localized full-length functional proteins. Exaluren disulfate is used for the research of cystic fibrosis caused by nonsense mutations[1][2].

In Vitro

Exaluren disulfate induces significant premature stop codon read-through with maintained native stop codon fidelity in DMS-114 cells, increasing p53 protein expression and reducing nonsense-mediated mRNA decay of TP53 mRNA[1].
Exaluren disulfate exhibits consistent nonsense mutation read-through activity and efficacy in human bronchial epithelial cells, Fischer rat thyroid cells, and a dual luciferase cystic fibrosis model[1].
Exaluren disulfate induces read-through of the CTNS W138X nonsense allele in human cystinosis fibroblasts, increasing cystinosin protein and CTNS mRNA levels while reducing half-cystine levels[1].

Exaluren (10 mg/kg; s.c.; 7 injections over a 3-week period) disulfate reduces kidney cell cystine levels by 30% in CTNSY226X nonsense mutant mice without overt renal toxicity[1].

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.
