  • Patent number: 10383859
    Abstract: The present invention provides a benzo[d]thiazole derivative or its pharmaceutically acceptable salt, a process for the preparation thereof, and a pharmaceutical composition comprising the same. The benzo[d]thiazole derivative or its pharmaceutically acceptable salt can selectively inhibit the protein-protein interaction between KRS and a laminin receptor (LR), thereby inhibiting migration of cancer cells. Therefore, the benzo[d]thiazole derivative or its pharmaceutically acceptable salt may be usefully applied for preventing or treating the diseases associated with cancer cell metastasis.
