  • 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: 20140336209
    Abstract: Provided is a compound that has the ability to promote axonal outgrowth in combination with the ability to promote angiogenesis and can therefore be used to reduce central nerve injuries such as head injury and spinal cord injury, cerebral infarction, ischemic heart diseases such as myocardial infarction and organic angina, peripheral arterial occlusive diseases such as critical limb ischemia, or after-effects of these diseases. Specifically, the compound is represented by the following formula (I): 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, an amino group or the like; 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, —CO— or the like; and Q is a hydrogen atom or a phenyl group.
