The purpose of this study is to investigate the mechanism of resistance to anticancer drugs based on cell biological theories and to find
natural substances that inhibit anticancer drug resistance. In this study, the colony formation assay method was used to find anticancer
drug resistance inhibitors. Based on the results of the experiments, five natural resources were presumed not to cause cytotoxicity in
human cells - Scrophularia buergeriana, Adenophora trachelioides, Bombyx mori Linne, Prunella Vulgaris var. aleutica Fernald,
Kalopanax pictus var typicus. Next, their solution extracts were exposed to with a cancer cell line that had acquired the resistance to
anticancer drugs. We then checked their medical capability as inhibitors. In this study, a strong inhibitory activity was observed in
the Bombyx mori Linne extracts. In addition, Hoechst 33342 staining was able to confirm the anticancer drug resistance. This study is
meaningful in that it will provide basic data for extracting substances for anticancer drug resistance from natural resources. However, the
medical potentials of the Bombyx mori Linne extracts as the inhibitor of anticancer drug resistance need to be scrutinized more through
follow-up mechanism studies.
