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. |

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. |
