Abstract

Official abstract text for this publication.

The present invention relates to a 2-hydroxyarylamide derivative or a pharmaceutically acceptable salt thereof, a preparation method thereof, and a pharmaceutical composition for preventing or treating cancer comprising the same as an active ingredient. The 2-hydroxyarylamide derivative prepared by the present invention is excellent in the inhibition of the activity of TMPRSS4 serine protease and the suppression of the infiltration of TMPRSS4-expressed cancer cells, and thus can be useful as a composition for preventing or treating cancer by inhibiting TMPRSS4 over-expressed in cancer cells, particularly, colorectal cancer, lung cancer, breast cancer, prostate cancer, ovarian cancer, pancreatic cancer, or stomach cancer cells.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for inhibiting colorectal cancer metastasis comprising: administrating a pharmaceutically effective dose of a 2-hydroxyarylamide derivative or a pharmaceutically acceptable salt thereof, wherein the 2-hydroxyarylamide derivative is selected from the group consisting of: (6) 5-chloro-2-hydroxy-N-(3-methoxy-5-(trifluoromethyl)phenyl)benzamide; (19) 5-chloro-N-(4-cyano-3-(trifluoromethyl)phenyl)-2-hydroxybenzamide; (25) 5-chloro-2-hydroxy-N-quinoline-3-yl-benzamide; (27) 5-chloro-N-(2-chloro-4-cyano-phenyl)-2-hydroxy-benzamide; (28) 5-chloro-2-hydroxy-N-(5-trifluoromethyl-[1,3,4]thiadiazole-2-yl)-benzamide; (32) 5-chloro-N-(4-chloro-3-(trifluoromethyl)phenyl)-2-hydroxybenzamide; (36) 5-chloro-2-hydroxy-N-(2-nitro-4-trifluoromethyl-phenyl)-benzamide; (37) 5-chloro-N-(5-cyano-pyridine-2-yl)-2-hydroxy-benzamide; and (53) 5-chloro-2-hydroxy-N-(4-phenylthiazole-2-yl)benzamide; wherein the 2-hydroxyarylamide derivative or a pharmaceutically acceptable salt thereof inhibits the activity of TMPRSS4 (transmembrane protease serine-4). 2. The method of claim 1 , wherein the 2-hydroxyarylamide derivative or a pharmaceutically acceptable salt thereof is administered orally or parenterally.
