In many cases of Alzheimer-type senile dementia, many cholinergic neurons of the Meinert nucleus, which is a nerve cell that controls memory and thought, die and are lost. Many researchers have revealed that NGF is essential for cell survival and differentiation (Pharmacia, 22, 147 (198).

Further, NGF acts as a trophic factor for not only central nerves but also peripheral sensory and sympathetic nervous systems, and is an essential factor for nerve regeneration.

However, NGF has a molecular weight of 10,000.
Since it is a protein exceeding 0 and NGF itself is used as a therapeutic agent, pharmacological and pharmacological restrictions are large. From these viewpoints, as a substantial and effective replacement therapy for NGF, it is important to search for a low molecular weight compound having the ability to induce the production and secretion of NGF in a specific tissue. Examples of the compound having such an action include catechol derivatives (Furukawa.Y., J. Bio).

Senile cataract is associated with lens membrane dysfunction, amino acid metabolism disorder, lipid peroxide production, glucose metabolism disorder, oxidative disorder,
It is thought that UV damage, immune function deterioration, etc. progress in a complicated combination. In addition, quinoid compounds (benzoquinone acetic acid, adrenochrom, adrenaline quinone, quinone imino acid, etc.), which are generally caused by abnormal metabolism of amino acids (tyrosine, tryptophan), denature and insolubilize the water-soluble proteins of the lens, resulting in cataract. The quinoid theory is influential. It is said that diabetic cataract is caused by direct damage of glucose, abnormal metabolites caused by diabetes, and sorbitol, a sugar alcohol accumulated in cells. In this case, since aldose reductase increases in diabetic patients, glucose is reduced to sorbitol and sorbitol is accumulated in the cells. As a result, it is said that the constituent proteins of the lens are aggregated, the amount of insoluble protein is increased, and the lens becomes cloudy. Pyrroloquinoline quinone (PQ
Q) (Japanese Patent Laid-Open No. 63-41421) is reported,
Its inhibitory activity is not sufficient, and higher active compounds are desired.
