  • Patent number: 8569058
    Abstract: A nerve regeneration which comprises a compound is represented by formula (I): (wherein all symbols are shown in the description), a salt thereof or a prodrug thereof. The compound of the present invention is suppresses nerve cell death as a substance for accelerating growth and/or differentiation of stem cells (nerve stem cells, embryonic stem cells, bone marrow cells, etc.), a substance for accelerating growth and/or differentiation of nerve precursor cells, a potentiator for neurotrophic factor activity, a neurotrophic factor-like substance or a neurodegenerative suppressor, and accelerates repair and regeneration of nerve tissues by neogenesis, regeneration and/or axon evolution. In addition, the compound of the present invention is useful for preparation from brain tissues, bone marrow and/or embryonic stem cells of cells for transplant (nerve stem cells, nerve precursor cells, nerve cells, etc.

  • Patent number: 7687489
    Abstract: A pharmaceutical composition for the treatment and/or prevention of cerebral ischemic diseases, which comprises two components, i.e. an astrocyte function-improving agent, preferably a compound represented by the formula (I): (wherein R6 is hydroxy, etc., (1) n is 1, R11 is hydrogen and R5 is (alkyl of which one carbon atom is substituted by fluorine)-CH2— or (2) n is 0 or 1, R11 is hydrogen, etc., and R5 is alkyl, etc.) and a thrombolytic agent, preferably tissue plasminogen activator, as active ingredients. The pharmaceutical composition of the present invention exhibits a synergistic therapeutic effect compared to independent administration of an astrocyte function-improving agent and a thrombolytic agent.
