Sodium 4-phenylbutyrate reduces myofiber damage in a mouse model of Duchenne muscular dystrophy
2016
We performed a placebo-controlled pre-clinical study to determine if sodium 4-phenylbutyrate (4PB) can reduce contraction-induced myofiber damage in the mdx mouse model of Duchenne muscular dystrophy (DMD). At 72 h post-eccentric contractions, 4PB significantly increased contractile torque and reduced myofiber damage and macrophage infiltration. We conclude that 4PB, which is approved by Health Canada (Pheburane) and the United States Food and Drug Administration (Buphenyl) for urea cycle disorders, might modify disease severity in patients with DMD.
