Abstract
A series of (+)-negamycin 1 analogues were synthesized, and their readthrough-promoting activity was evaluated for nonsense mutations in Duchenne muscular dystrophy (DMD). A structure-activity relationship study indicated that 11b was the most potent drug candidate. Immunohistochemical analyses suggested that treatment with 11b restored dystrophin expression in mdx mice, a DMD mouse model. Furthermore, 11b decreased serum creatine kinase (CK) levels, an indicator of muscle fiber destruction. Most importantly, 11b demonstrated lower toxicity than 1, and thus, it could be a useful candidate for long-term treatment of DMD.
