The compositions are used to inhibit Maillard's reaction in human body, the reaction which may be responsible for the development of diabetic complications and age-associated disorders. Methods of treatment and prophylaxis of such complications and disorders are also presented.
摘要:
Provided are dental plaque inhibitor compositions comprising a compound of the formula: wherein R₁, R₂ and R₃ are the same or different and each is a hydrogen atom or a methyl group or a pharmaceutically acceptable salt thereof. The compositions inhibit the formation of dental plaque by inhibiting the transformation of sucrose into insoluble polysaccharides.
摘要:
The present invention relates to a pharmaceutical composition for the prophylaxis and treatment of ischemic disorder in mammalian organs which contains, as an ingredient, a compound of the formula: wherein R₁, R₂ and R₃ are independently the methyl group or a hydrogen atom, or a salt thereof.
摘要:
Phosphoric diesters of general formula: [wherein R₁ and R₂ are the same or different and each means a methyl group or a hydrogen atom, provided that at least one of R₁ and R₂ is a hydrogen atom, or a salt thereof] can be produced by reacting β, γ or δ-tocopherol with a halophosphorylating agent such as phosphorus oxychloride, reacting the resultant product with ascorbic acid whereof hydroxyl groups at 5- and 6-positions are protected, and then removing protected groups from the hydroxy groups. The phosphoric diesters are novel compounds having antiinflammatory activity.
摘要:
The compounds represented by the general formula wherein R is an alkyl group having 1-10 carbon atoms are novel compounds which have not been reported in the literature. Since they have excellent affinities for tissues with particular high corneal permeability and show anticataract activity at low concentration, the compounds are of value as prophylactic and therapeutic agents for cataract.
摘要:
An ophthalmic topical agent for remedy of diseases of iris and ciliary body containing 5-(3-ethoxy-4-pentyloxyphenyl)-2,4-thiazolidinedion and/or a physiological acceptable salt as an active ingredient.
摘要:
A compound represented by the formula (wherein X represents a hydrogen atom or a halogen atom) provided in accordance with the invention are novel compound of value as nonsteroidal antiinflamatory agents. Alpha-tocopherol 5-halouridine phosphoric acid diesters, in particular, are expected to be employable for antitumor agents as well.
摘要:
Phosphoric acid diesters of the formula: and salts thereof are produced by reacting a-tocopherol with a halogenophosphorylating agent, reacting the resultant product with ascorbic acid having protecting hydroxy groups in the 5- and 6-positions, and removing the protected groups. The compounds can be employed as prophylactic and therapeutic agents for cataracts and climacteric hazards and also as an ingredient for cosmetics having skin-beautifying action.
摘要:
