产品介绍
Ataluren (PTC124) 是可口服的CFTR-G542X无义等位基因抑制剂。
生物活性

Ataluren (PTC124) is an orally availableCFTR-G542Xnonsense allele inhibitor.

IC50& Target

CFTR[1]

体外研究
(In Vitro)

This premature “stop” signal (a class I mutation) prevents the cell from producing a full-length CFTR protein[1]. Ataluren (PTC124)-a new chemical entity that selectively induces ribosomal readthrough of premature but not normal termination codons[2].

体内研究
(In Vivo)

Ataluren (PTC124) activity, optimized using nonsense-containing reporters, promotes dystrophin production in primary muscle cells from humans andmdxmice expressing dystrophin nonsense alleles, and rescues striated muscle function inmdxmice within 2-8 weeks of drug exposure. Ataluren (PTC124) is well tolerated in animals at plasma exposures substantially in excess of those required for nonsense suppression[2]. To induce nonsense suppression and increase PPT1 enzyme activity, the read-through drug Ataluren (PTC124) is given via intraperitoneal (i.p.) injection to maleCln1R151Xmice at 2 months of age. These treatments are performed four times daily for 2 consecutive days in a proof-of-principle study. Used at 10 mg/kg, Ataluren (PTC124) increased PPT1 enzyme activity (P=0.0001 by unpaired t-test) and protein level (P=0.0014 by unpaired t-test) in the liver, but did not increase PPT1 enzyme activity or protein level in the cortex. This tissue-specific effect is likely due to the inability of Ataluren (PTC124) to breach the blood brain barrier (BBB), which decreased the bioavailability of Ataluren (PTC124) within the brain, and prevented Ataluren (PTC124) from reaching an efficacious concentration within the therapeutic window[3].
