  • Patent number: 8252945
    Abstract: As a result of intensive studies for the purpose of finding a new medicinal use of an indazole derivative, it was found that an indazole derivative inhibits glutamate-induced retinal neuronal cell death in rat fetal retinal neuronal cells, in other words, the indazole derivative acts directly on the retinal neuronal cells and exhibits an effect of protecting retinal neuronal cells. Accordingly, the indazole derivative is useful for the prevention or treatment of an eye disease associated with retinal neuronal cell damage or retinal damage.
