RECEPTOR TYROSINE KINASE INHIBITOR-RESISTANT ANTICANCER DRUG COMPOSITION COMPRISING 3,4,5-TRIHYDROXYBENZOIC ACID, DERIVATIVE THEREOF OR SALT THEREOF AS ACTIVE INGREDIENT

摘要

The present invention relates to a composition for preventing or treating a cancer resistant to a target anticancer drug, the composition including, as an active ingredient, a 3,4,5-trihydroxybenzoic acid (gallic acid) compound or a derivative thereof which specifically inhibits cancer cells that exhibit resistance to an anticancer drug targeting receptor tyrosine kinase. Since the 3,4,5-trihydroxybenzoic acid (gallic acid) compound or a derivative thereof specifically kills cancer cells that exhibit resistance to an anticancer drug targeting receptor tyrosine kinase, cancer diseases that are resistant to a receptor tyrosine kinase inhibitor such as gefitinib can be prevented or treated.
