Abstract

A new class of pseudo-trisaccharide aminoglycosides having an alkyl group at the 5″ position, exhibiting efficient stop codon mutation readthrough activity, low cytotoxicity and high selectivity towards eukaryotic translation systems are provided. Also provided are pharmaceutical compositions containing the same, and uses thereof in the treatment of genetic disorders, as well as processes of preparing these aminoglycosides. The disclosed aminoglycosides can be represented by the general formula I:

or a pharmaceutically acceptable salt thereof, wherein R 1 is selected from the group consisting of alkyl, cycloalkyl and aryl; and all other variables and features are as described in the specification.

First claim

What is claimed is:

1. A method for treating a genetic disorder associated with a premature stop codon mutation, the method comprising administering to a subject in need thereof a therapeutically effective amount of the compound:

or a pharmaceutically acceptable salt thereof.

2. The method of claim 1 , wherein the genetic disorder is selected from the group consisting of cystic fibrosis (CF), Duchenne muscular dystrophy (DMD), ataxia-telangiectasia, Hurler syndrome, hemophilia A, hemophilia B, Usher syndrome, Tay-Sachs Becker muscular dystrophy (BMD), Congenital muscular dystrophy (CMD), Factor VII deficiency, Familial atrial fibrillation, Hailey-Hailey disease, McArdle disease, Mucopolysaccharidosis, Nephropathic cystinosis, Polycystic kidney disease, Rett syndrome, Spinal muscular atrophy (SMA), X-linked nephrogenic diabetes insipidus (XNDI) and X-linked retinitis pigmentosa.

3. The method of claim 1 , further comprising administering to the subject an additional agent useful in treating the genetic disorder.

4. A pharmaceutical composition being packaged in a packaging material and identified in print, in or on said packaging material, for use in the treatment of a genetic disorder associated with a premature stop codon mutation, the composition comprising the compound:

or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier.

5. The pharmaceutical composition of claim 4 , wherein said genetic disorder is selected from the group consisting of cystic fibrosis (CF), Duchenne muscular dystrophy (DMD), ataxia-telangiectasia, Hurler syndrome, hemophilia A, hemophilia B, Usher syndrome, Tay-Sachs Becker muscular dystrophy (BMD), Congenital muscular dystrophy (CMD), Factor VII deficiency, Familial atrial fibrillation, Hailey-Hailey disease, McArdle disease, Mucopolysaccharidosis, Nephropathic cystinosis, Polycystic kidney disease, Rett syndrome, Spinal muscular atrophy (SMA), X-linked nephrogenic diabetes insipidus (XNDI) and X-linked retinitis pigmentosa.
