摘要:
4-Hydroxypyridine derivative represented by the following formula ##STR1## wherein R represents a methyl group or an isopropyl group, and the method for preparing the derivative comprising the step of cultivating a strain belonging to Streptomyces karnatakensis are disclosed. Also disclosed are the pharmaceutical composition comprising the same and a method for treating circulatory diseases comprising the step of administering said compound to a patient.
摘要:
Compounds of the formula (I) ##STR1## wherein R is a hydrogen atom or a C.sub.1-6 alkyl group and n is an integer of 0 or 1, and pharmaceutical preparations thereof are provided. These pharmaceutical preparations are useful for the prevention or treatment of diseases associated with an abnormality in immunological regulatory function or vascularization.
摘要:
Salicylamide derivatives represented by formulae (1a) and (1b); intermediates in the production thereof; a process for producing the same; and drugs containing the same as the active ingredient. The salicylamide derivatives represented by formulae (1a) and (1b) are useful as anti-inflammatory agents and immunosuppressive agents which exert an effect of inhibiting the activation of NF-&kgr;B with little side effects.
摘要:
Optically active 1,4-dihydropyridine derivatives represented by general formula (I) and anion salts thereof and a production method therefor: ##STR1## (wherein R.sup.1 represents a C.sub.1-6 alkyl group, R.sup.2 represents a nitrogen-containing heterocyclic group forming a quaternary ammonium which may be substituted, and n is an integer of 1, 2 or 3). The optically active 1,4-dihydropyridine derivatives represented by general formula (I) have vasodilating activity and hypotensive activity and are excellent in water solubility so that they are useful as a drug for circulatory system such as a hypotensor or vasodilator.
