摘要

The present invention relates to a compound expressed in the following chemical formula 1, to an isomer thereof, or to a pharmaceutically allowable salt thereof. The compound expressed in chemical formula 1 inhibits the tyrosine kinase activity of Discoidin Domain Receptor 1 (DDR1) and Discoidin Domain Receptor 2 (DDR2), and thus can be valuably used in the prevention or treatment of diseases such as a cancer, hepatocirrhosis, arteriosclerosis, rheumatoid arthritis, osteoarthritis, and the like, which are known to be mainly caused by an excessive activation of Discoidin Domain Receptor 1 or Discoidin Domain Receptor 2.
