Descrizione

Descrizione generale

A cell-permeable, non-toxic, orally bioavailable oxadiazole compound that is reported to promote read-through of premature, but not normal, translation termination codons and thereby suppress premature termination in protein synthesis caused by nonsense mutations (in ~10 to 100 nM with maximal activity reported at 3 µM). Promotes the suppression of nonsense alleles of the dystrophin gene in primary human muscle cells and in a mouse model of Duchenne muscular dystrophy (mdx). Also reported to rescue striated muscle function in mdx mice with a noticeable reduction in their serum creatine kinase values. Subcutaneous or oral administration of PTC124 to a mice expressing human CFTR-G542X transgene is shown to suppress G542X nonsense mutation and restore hCFTR function and cAMP-stimulated chloride channel activity (60 mg/kg for 3 weeks). Also acts as a potent and reversible inhibitor of purified firefly luciferase (FLuc; IC₅₀ ~ 10 nM) and protects it from tryptic degradation, but does not affect Renilla reniformis luciferase (RLuc).
