Novel compound having tumor diagnosis or tumor growth inhibitory activity on EGFR mutant and medical uses comprising the same

摘要

The present invention relates to a novel compound having activities of diagnosing a tumor having an epidermal growth factor receptor (EGFR) mutant and inhibiting tumor growth, a salt thereof, a contrast medium comprising the same, and a pharmaceutical composition for treating or preventing EGFR-related cancer diseases comprising the same as an active ingredient. The novel compound or the salt thereof according to the present invention does not inhibit a wild type EGFR but selectively inhibits an EGFR variant, and thus can treat and prevent EGFR-related cancer diseases, including lung cancer, colon cancer or breast cancer. Particularly, the compound or the salt thereof according to the present invention can effectively treat and prevent non-small cell lung cancer upon which Iressa or Tarceva cannot have any significant effect. In addition, the compound or the salt thereof according to the present invention responses with a target of Gefitinib-sensitive cancer cells or cancer cells showing EGFR T790M mutation rather than wild type EGFR over-expressed cancer cells, and thus can be used advisably as a contrast medium capable of clearly differentiating EGFR-related cancer cells by imaging.
