Abstract:
The present invention relates to a pharmaceutical composition for preventing or treating inflammatory bowel disease, containing, as an active ingredient, a pyridinol derivative or a pharmaceutically acceptable salt thereof. A pyridinol derivative represented by chemical formula 1 or a pharmaceutically acceptable salt thereof has an excellent colitis inhibitory effect in an inflammatory bowel disease model, and thus can be useful as a medicine for preventing or treating inflammatory bowel disease.

Claim (Index 1):
A compound represented by Formula 1 or pharmaceutically acceptable salt thereof: wherein R 2 , R 3  and R 4  are each independently alkyl having 1 to 8 carbon atoms, R 5  is any one selected from the group consisting of hydrogen; halogen; alkyl having 1 to 8 carbon atoms; \u2014Si(R 6 ) 3 ; and aryl having 6 to 18 carbon atoms, wherein the alkyl having 1 to 8 carbon atoms or aryl having 6 to 18 carbon atoms of R 5  is each independently substituted with alkyl having 1 to 8 carbon atoms or aryl having 6 to 18 carbon atoms, or not substituted, R 6  is any one selected from the group consisting of hydrogen, alkyl having 1 to 8 carbon atoms and aryl having 6 to 18 carbon atoms, R 1  is any one selected from the group consisting of hydrogen; sulfonyl; carbonyl; alkyl having 1 to 12 carbon atoms; and aryl having 6 to 18 carbon atoms, wherein the sulfonyl or carbonyl of R 1  is each independently substituted or not substituted with one or more substituents selected from the group consisting of alkyl having 1 to 8 carbon atoms, which is substituted or not substituted with a halogen; and aryl having 6 to 18 carbon atoms, which is substituted or not substituted with alkyl having 1 to 8 carbon atoms or halogen, and the alkyl having 1 to 12 carbon atoms or aryl having 6 to 18 carbon atoms of R 1  is each independently substituted or not substituted with one or more selected from the group consisting of halogen; \u2014NO 2 ; alkyl having 1 to 8 carbon atoms, which is substituted or not substituted with halogen; alkoxy having 1 to 8 carbon atoms, which is substituted or not substituted with halogen; and aryl having 6 to 18 carbon atoms, which is substituted or not substituted with alkyl having 1 to 8 carbon atoms or halogen, L is \u2014O\u2014 or a linker represented by Formula 2 or 3 below, in Formula 2, Q is O or S, and P is \u2014NH\u2014 or \u2014O\u2014, and in Formula 3, Z is a single bond or \u2014NH\u2014.
