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.

First claim

What is claimed is:

R 1 is hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, —(CH 2 CH 2 O) n R 6 or any biohydrolyzable group;
R 2 , R 3 , R 4 , R 5 and R 6 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, CF 3 , OCF 3 , OCHF 2 , CN, COOH, COOR 7 , SO 2 R 7 , NO 2 , NH 2 , or N(R 7 ) 2 ;
each occurrence of R 7 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 CF 3 ; and
n is an integer from 1 to 7.

2. The method of claim 1 , wherein the compound has 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; and R is hydrogen or halogen.

3. The method of claim 1 , wherein the compound has the formula:

or a pharmaceutically acceptable salt thereof, wherein:
Z is substituted or unsubstituted aryl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted arylalkyl;
R 1 is hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, or —(CH 2 CH 2 O) n R 6 ;
R 2 , R 3 , R 4 , R 5 and R 6 are independently hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl; substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, alkoxy, aryloxy, halogen, CF 3 , OCF 3 , OCHF 2 , CN, COOH, COOR 7 , SO 2 R 7 , NO 2 , NH 2 , or N(R 7 ) 2 ;
each occurrence of R 7 is independently hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl; substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, alkoxy, aryloxy, halogen or CF 3 ; and
n is an integer from 1 to 7.

4. The method of claim 1 , wherein the compound has the formula:

or a pharmaceutically acceptable salt thereof, wherein:
Z is substituted aryl, substituted or unsubstituted cycloalkyl, substituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted arylalkyl;
R 1 is hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, —(CH 2 CH 2 O) n R 6 or any biohydrolyzable group;
R 2 , R 3 , R 4 , R 5 and R 6 are independently hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl;
substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, alkoxy, aryloxy, halogen, CF 3 , OCF 3 , OCHF 2 , CN, COOH, COOR 7 , SO 2 R 7 , NO 2 , NH 2 , or N(R 7 ) 2 ;
each occurrence of R 7 is independently hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl; substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, alkoxy, aryloxy, halogen or CF 3 ; and
n is an integer from 1 to 7.

5. The method of claim 1 , wherein the compound has the formula:

or a pharmaceutically acceptable salt thereof, wherein:
X is halogen, substituted alkyl, alkoxy or hydroxy;
R 1 is hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, —(CH 2 CH 2 O) n R 6 or any biohydrolyzable group;
R 2 , R 3 , R 4 , R 5 and R 6 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, CF 3 , OCF 3 , OCHF 2 , CN, COOH, COOR 7 , SO 2 R 7 , NO 2 , NH 2 , or N(R 7 ) 2 ;
each occurrence of R 7 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 CF 3 ; and
