Abstract: The present invention relates to a novel benzopyran derivative useful for preparing a drug for treating cancer, and more specifically, to a novel benzopyran derivative which is a micromolecule having a macrophage inhibitory effect and is useful for preparing a drug for cancer treatment. The drug particularly inhibits the differentiation of immune macrophages to stimulate the immune system, and thus is useful for treating immune-related cancers.

Abstract: Disclosed are a composition and a method for diagnosing breast cancer using extracellular vesicle-miRNA. The composition for diagnosing the breast cancer according includes an agent that measures an expression level of at least one miRNA selected from a group consisting of miR-9, MiR-16, MiR-21, and MiR-429. Furthermore, the method for diagnosing breast cancer includes measuring an expression level of at least one miRNA selected from a group consisting of MiR-9, MiR-16, MiR-21, and MiR-429 from a sample, and diagnosing the breast cancer based on the measurement result.
