Abstract: The present disclosure provides a compound of a specific chemical structure or a pharmaceutically acceptable salt thereof, which has the activity of inhibiting and/or degrading mutant EGFR protein. The present disclosure also provides a composition comprising such a compound or a pharmaceutically acceptable salt thereof. The present disclosure provides a pharmaceutical use of a compound according to the present disclosure, a salt thereof, and a composition comprising same for the treatment or prevention of cancer with EGFR mutation, especially lung cancer. The present disclosure also provides a method for treatment or prevention of EGFR mutation cancer, especially lung cancer, the method comprising administering an effective amount of the compound according to the present invention, a salt thereof, or a composition containing same to a subject in need of treatment.

Abstract: A novel deuterium-substituted pyrimidine derivative compound of Formula 1, or a pharmaceutically acceptable salt thereof is disclosed. A composition containing the compound and uses thereof in treating cancer are also disclosed.

Abstract: The present invention provides a novel compound represented by Chemical Formula 1 or a salt thereof and a pharmaceutical composition for treating lung cancer containing same. A pyrimidine derivative compound represented by Chemical Formula 1 effectively inhibits the growth of cancer cells with an ALK mutation and an EGFR mutation, thereby being effectively usable in the treatment of lung cancer.

Abstract: A novel pyrimidine derivative compound and a salt thereof are disclosed. The pyrimidine derivative compound effectively inhibits the growth of C797S mutant EGFR-expressed and MET-amplified cancer cells, which are the main resistance mechanisms of third generation EGFR anticancer agents, and thus may be effectively used in the treatment of lung cancer.
