Abstract
Novel 1,2,4-oxadiazole benzoic acid compounds, methods of using and pharmaceutical compositions comprising an 1,2,4-oxadiazole benzoic acid derivative are disclosed. The methods include methods of treating or preventing a disease ameliorated by modulation of premature translation termination or nonsense-mediated mRNA decay, or ameliorating one or more symptoms associated therewith.
Claims20
A method for treating a disease or disorder associated with a nonsense mutation in a patient having a disease or disorder associated with a nonsense mutation, comprising administering to the patient a therapeutically effective amount of a compound having the formula:
- or a pharmaceutically acceptable salt thereof, wherein:
- Z is substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted heterocycle, substituted or unsubstituted arylalkyl;
- R1 is hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl or —(CH2CH2O)nR6;
- R2, R3, R4, R5 and R6 are independently hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl;
- substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, alkoxy, aryloxy, heteroaryloxy, halogen, CF3, OCF3, OCHF2, CN, COOH, COOR7, SO2R7, NO2, NH2, or N(R7)2;
- each occurrence of R7 is independently hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl;
- substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, alkoxy, aryloxy, heteroaryloxy, halogen or CF3;
- and
- n is an integer from 1 to 7,
- wherein the disease or disorder associated with a nonsense mutation is cystic fibrosis, a muscular dystrophy, retinitis pigmentosa, hemophilia, ataxia-telangiectasia, tuberous sclerosis, neurofibromatosis, Marfan syndrome, Parkinson's disease, mucopolysaccharidosis type III A, mucopolysaccharidosis type VI or mucopolysaccharidosis type VII.
A method for increasing the expression of full-length dystrophin protein in a patient having a muscular dystrophy, comprising administering an effective amount of 3-[5-(2-fluoro-phenyl)-[1,2,4]oxadiazol-3-yl]-benzoic acid or a pharmaceutically acceptable salt thereof to said patient.
A method for increasing the expression of full length CFTR protein in a patient having cystic fibrosis, comprising administering an effective amount of 3-[5-(2-fluoro-phenyl)-[1,2,4]oxadiazol-3-yl]-benzoic acid or a pharmaceutically acceptable salt thereof to said patient.
