摘要:
Aminophenol derivatives of the following formula (I) ##STR1## wherein X is hydrogen atom, lower alkyl or a protecting group for phenolic hydroxy, Y is hydrogen atom or lower alkyl, Z is hydrogen atom, lower alkyl, halogen atom or trifluoromethyl, A is hydrogen atom or lower alkyl, t is an integer of 1 to 5, l and m are respectively an integer of 2 to 4, E and W are nitrogen atoms, F is a direct bond or oxygen atom, P and Q are each hydrogen atom, halogen atom, lower alkyl or lower alkoxy, and R.sup.8 is hydrogen atom, hydroxy or a hydroxy-protecting group, and their pharmcologically acceptable salts. Since the aminophenol derivatives (I) of the present invention have excellent antioxidative action and antiinflammatory and antiallergic action in mammalian animals including human, they are extremely useful as pharmaceuticals such as an antiinflammatory or an antiallergic.
摘要:
An agent for the prophylaxis and treatment of immune-related diseases, in particular, immunosuppressant, an agent for the prophylaxis and treatment of allergic diseases, an agent for the prophylaxis and treatment of eosinophil-related diseases and an eosinophilia inhibitor, comprising, as an active ingredient, a series of triazole derivatives of the following formula (I) ##STR1## or the following formula (III) ##STR2## wherein each symbol is as defined in the specification, or a pharmaceutically acceptable salt thereof. A novel monocyclic or bicyclic triazole derivative. The agent for the prophylaxis and treatment of immune-related diseases, in particular, immunosuppressant, the agent for the prophylaxis and treatment of allergic diseases, the agent for the prophylaxis and treatment of eosinophil-related diseases, the eosinophilia inhibitor and the novel triazole derivative of the present invention all, have superior eosinophilia-inhibitory action and lymphocyte activation-inhibitory action. They are low toxic and persistent in action. They are particularly effective in the treatment of accumulation and activation of eosinophil and lymphocytes, inflammatory respiratory tract diseases, eosinophil-related diseases such as eosinophilia, and immune-related diseases.
摘要:
The present invention relates to a novel sulfonic acid derivative of hydroxamic acid or a pharmacologically acceptable salt thereof. More particularly, the present invention relates to a sulfonic acid derivative of hydroxamic acid or a pharmacologically acceptable salt thereof, which is useful as an inhibitor of lipopolysaccharides (LPS). In addition, the present invention relates to a novel intermediate compound useful for the synthesis of this sulfonic acid derivative of hydroxamic acid.
