摘要:
A compound of the general formula: (I) (wherein the ring A represents a substituted or unsubstituted cyclic group; Q a substituted or unsubstituted alkyl or a substituted or unsubstituted cyclic group; the ring D a substituted or unsubstituted cyclic group; W a bond or a spacer with a principal chain of 1 to 4 atoms; and Y a spacer with a principal chain of 1 to 4 atoms), or its salt, N-oxide or solvate, or a prodrug thereof. The compound of the general formula (I), or its salt, N-oxide or solvate, or a prodrug thereof has affinity with MBR, thereby being useful as a preventive and/or curative drug for diseases caused by stress.
摘要:
Nitrogen-containing 5-membered cyclic compounds represented by the general formula (I) and nontoxic salts thereof, wherein each symbol is as defined in the description. Because of having a cysteine protease inhibitory activity, the compounds of the general formula (I) are useful as preventives and/or remedies for inflammatory diseases, diseases caused by apoptosis, diseases caused by immune response error, autoimmune diseases, diseases caused by the degradation of biological constituent proteins, shock, circulatory error, blood coagulation error, malignant tumor, acquired immunological deficiency syndrome (AIDS), AIDS related complex (ARC), parasitogenic diseases, neurodegenerative diseases, lung disorder, bone resorption diseases, hyper endocrine diseases, etc.
摘要:
Oxadiazole derivatives represented by general formula (I) (wherein R1 represents hydrogen or an amino-protecting group; and R?2, R3, and R4¿ each independently represents alkyl, cycloalkyl, optionally substituted phenyl, or 3,4-methylenedioxyphenyl, provided that R?3 and R4¿ may in combination represent C¿2-6? alkylene); and a process for producing an oxadiazole derivative represented by general formula (II) (wherein all symbols have the same meanings as the above) from any of the derivatives represented by general formula (I). By the process, a compound represented by general formula (II) can be produced in high yield through a smaller number of steps.
摘要:
The present invention relates to a diketohydrazine derivative of formula (I) and a pharmaceutically acceptable salt thereof (the symbols in the formula have the same meaning as described in the specification). The compound of formula (I) has an inhibitory activity against cysteine protease, and it is useful for the treatment of inflammatory diseases, immune diseases, ischemic diseases, respiratory diseases, circulatory diseases, blood diseases, neuronal diseases, hepatic or biliary diseases, osseous or articular diseases, metabolic diseases, etc. And the compound has inhibitory activity against elastase and it is also useful for the treatment of COPD (chronic obstacle pulmonary diseases).
摘要:
Form 2 crystals of 2-[5-amino-6-oxo-2-phenyl-1,6-dihydro-1-pyrimidyl]-N-[1-(2-[5-t-butyl-1,3,4-oxadiazolyl]carbonyl)-2-R,S)-methylpropyl]acetamide (I); a process for producing the crystals; and medicines containing the same as the active ingredient.
摘要:
Benzene-fused heterocycle derivatives of the general formula (I); and nontoxic salts thereof (wherein each symbol is as defined in the description). The compounds of the general formula (I) exhibit inhibitory activities against cysteine proteases and are useful as preventive and/or therapeutic drugs for immunopathy (such as autoimmune diseases and infectious diseases), inflammatory diseases (such as inflammatory diseases of intestine, multiple encephalosclerosis, and arthritis), nerve degeneration diseases (such as Alzheimer's disease and muscular dystrophy), bone resorptive diseases (such as osteoporosis), respiratory diseases, diabetes, shock, and so on.
