Inhibitor of aspartic acid synthesis in tumor cells, inhibitor of spheroid formation of tumor cells, inhibitor of tumor cell metastasis, activity enhancer of glycolytic inhibitor, and pharmaceutical composition for suppressing and/or preventing tumor metastasis

Abstract

Provided is a highly safe metastasis inhibitor of tumor cells that can be substituted for a conventionally known metastasis inhibitor of tumor cells. A compound represented by Chemical Formula 1A or Chemical Formula 1B described in the description is used as an aspartic acid synthesis inhibitor in tumor cells, a spheroid formation inhibitor of tumor cells, or an action enhancer of glycolysis inhibitors. These inhibitors have a function as a highly potent metastasis inhibitor of tumor cells.
