  • Patent number: 9156817
    Abstract: Compounds of Formula (I) promote axonal outgrowth angiogenesis and can therefore be used to reduce central nerve injuries such as head injury and spinal cord injury, cerebral infarction, ischemic heart diseases, peripheral arterial occlusive diseases, or after-effects of these diseases. in which Nx group is preferably a 6-membered aromatic ring containing two nitrogen atoms; R0, R1 and R2 are each independently a hydrogen atom, an alkyl group, or an amino group; E is an oxygen atom or an —NR8 group (wherein R8 is an alkyl group or the like); n is an integer of 0 to 5; X and Y are each a connecting bond, a cycloalkyl group, or —CO—; and Q is a hydrogen atom or a phenyl group.

  • Publication number: 20150265680
    Abstract: The present invention provides a therapeutic agent for amyotrophic lateral sclerosis comprising a growth hormone secretagogue receptor (GHS-R) agonist or a pharmaceutically acceptable salt thereof as an active ingredient. An object of the present invention is to provide a pharmaceutical product for amyotrophic lateral sclerosis for which no effective drug exists. The therapeutic agent for amyotrophic lateral sclerosis of the present invention comprises a GHS-R agonist typified by ghrelin as an active ingredient and is administered to a recipient individual having amyotrophic lateral sclerosis with non-serious dysphagia. The individual may also be unresponsive or insufficiently responsive to an existing therapeutic agent for ALS.
