Summary for Patent: 8,436,049
Title:Uses of pentamidine and related compounds
Abstract: Methods are provided herein for treatment of myotonic dystrophy and other toxic RNA diseases in a subject. In some examples, the method comprises administration of a compound that binds a nucleotide repeat expansion in a ribonucleic acid molecule, thereby treating the disease. In additional examples, the method comprises administration of a compound that disrupts binding of muscleblind-like proteins to an RNA nucleotide repeat expansion. Compounds for use in the disclosed method include pentamidine or heptamidine or derivatives thereof. Representative compounds are described herein.
Inventor(s): Berglund; John Andrew (Eugene, OR), Warf; M. Bryan (Eugene, OR), Matthys; Catherine (Eugene, OR), Haley; Michael M. (Eugene, OR), Hilton; Cameron L. (Eugene, OR)
Assignee: State of Oregon Acting By and Through the State Board of Higher Education on behalf of the University of Oregon (Eugene, OR) N/A (N/A)
Application Number:12/918,696
Patent Claims:1. A method of treating myotonic dystrophy in a subject, comprising administering to the subject a compound, diamidine having the structure ##STR00020## wherein n=2-7, that binds a nucleotide repeat expansion in a ribonucleic acid molecule, thereby treating myotonic dystrophy.

2. The method of claim 1, wherein the nucleotide repeat expansion comprises a trinucleotide repeat expansion.

3. The method of claim 2, wherein the trinucleotide repeat expansion comprises a CUG repeat.

4. The method of claim 1, wherein the nucleotide repeat expansion comprises a trinucleotide repeat expansion in the pre-mRNA or mRNA of the dystrophia myotonica-protein kinase gene.

5. The method of claim 1, wherein the nucleotide repeat expansion comprises a tetranucleotide repeat expansion.

6. The method of claim 5, wherein the tetranucleotide repeat expansion comprises a CCUG repeat.

7. The method of claim 1, wherein the nucleotide repeat expansion comprises a tetranucleotide repeat expansion in a zinc finger 9 ribonucleic acid.

8. The method of claim 1, wherein the diamidine comprises pentamidine or heptamidine.

9. The method of claim 1, wherein the compound diamidine having the structure ##STR00021## wherein n=2-7, that binds the nucleotide repeat expansion disrupts the binding of muscleblind-like proteins to CUG repeats of dystrophia myotonica-protein kinase.

10. The method of claim 1, wherein the compound diamidine having the structure ##STR00022## wherein n=2-7, that binds the nucleotide repeat expansion disrupts binding of muscleblind-like proteins to CCUG repeats within intron 1 of zinc finger 9 pre-mRNA.

11. A method of treating myotonic dystrophy caused by toxic RNA in a subject, comprising administering to the subject a compound, diamidine having the structure ##STR00023## wherein n=2-7, that binds a nucleotide repeat expansion in a ribonucleic acid molecule, thereby treating the disease caused by toxic RNA.

12. A method of treating myotonic dystrophy caused by toxic RNA in a subject, comprising administering to the subject a compound, diamidine having the structure ##STR00024## wherein n=2-7, that displaces muscleblind-like (MBNL) protein from a nucleotide repeat expansion in a ribonucleic acid molecule, thereby treating the disease caused by toxic RNA.

13. The method of claim 11, wherein the diamidine comprises pentamidine or heptamidine.
