    摘要: A pyridine derivative represented by the following formula: ##STR1## where R.sup.1 and R.sup.2 are as defined in the specification, or a salt thereof. These compounds directly or indirectly act on neuronal cells in vivo and are effective in the amelioration and curing of nerve disorders due to neuronal degeneration, such as, for example, traumatic symptoms and maladies, disorders induced by drugs such as alcohol and antineoplastic agents, inflammatory disorders, metabolic disorders observed in diabetes, and disorders due to idiopathic degeneration of peripheral nerves. These compounds are also effective for ameliorating and curing symptoms and maladies due to degeneration of central nerves, for example, Alzheimer's disease and cerebrovascular ischemia, Down's syndrome, Parkinson's disease, Huntington's chorea, diseases secondary to cerebral ischemia, cerebral infarction, intracerebral bleeding, head injuries, amnesia, and spinal neuropathy.

    摘要: A novel phthalocyanine compound having improved solubility and high purity and containing a polymerizable vinyl group within its molecule is provided. Intermediates to this phthalocyanine compound also have improved solubility and high purity. Further, with the novel phthalocyanine compound used as a starting monomer, a novel polymer is obtained which has a high content of (metal) phthalocyanine and is easy to control the orientation of phthalocyanine rings. The polymer having improved solubility and high purity is expected of use as functional material such as catalysts and recording material.
