摘要:
The present invention provides a 2,3-dihydro-6-nitroimidazo[2,1-b]oxazole compound represented by the following general formula: wherein R 1 represents a hydrogen atom or C1-C6 alkyl group, n represents an integer of 0 to 6, R 2 represents a group -OR 3 or the like, and R 3 represents a hydrogen atom, C1-C6 alkyl group or the like, or R 1 and -(CH 2 ) n R 2 may bind to each other together with carbon atoms adjacent thereto through nitrogen atoms so as to form a spiro ring represented by the general formula (H): wherein R 41 is hydrogen, C1-C6 alkyl group or the like. The present compound has an excellent bactericidal action against Mycobacterium tuberculosis, multi-drug-resistant Mycobacterium tuberculosis, and a typical acid-fast bacteria.
摘要:
The present invention provides a novel diazepine compound that blocks the I Kur current or the Kv1.5 channel potently and more selectively than other K + channels. The present invention relates to a diazepine compound represented by General Formula (1) or a salt thereof, wherein R 1 , R 2 , R 3 , and R 4 are each independently hydrogen, lower alkyl, cyclo lower alkyl or lower alkoxy lower alkyl; R 2 and R 3 may be linked to form lower alkylene; A 1 is lower alkylene optionally substituted with one or more substituents selected from the group consisting of hydroxyl and oxo; Y 1 and Y 2 are each independently -N= or -CH=; and R 5 is group represented by (2) wherein R 6 and R 7 are each independently hydrogen or organic group; R 6 and R 7 may be linked to form a ring together with the neighboring group -X A -N-X B -; X A and X B are each independently a bond, lower alkylene, etc.
摘要:
This invention relates to a cyanotriazole compound represented by the formula (1): wherein each symbols are defined in the specification, or a salt thereof. The compound or a salt thereof stimulates the citric acid cycle activity and/or improves hyperglycemia with less side effects, and excellent safety, and therefore, it is useful for treating and/or preventing diseases or disorders on which citric acid cycle activation and/or improvement of hyperglycemia has a prophylactic and/or therapeutic effect, for example, diabetes, impaired glucose tolerance, insulin resistance, diabetic complications, obesity, dyslipidemia, hepatic steatosis, atherosclerosis and/or cardiovascular disease, as well as diseases or disorders that would benefit from stimulating energy expenditure.
摘要:
The present invention provides a 2,3-dihydro-6-nitroimidazo[2,1-b]oxazole compound represented by the following general formula: (1)in the above formula (1), R1 represents a hydrogen atom or C1-C6 alkyl group, n represents an integer of 0 to 6, R1 and -(CH2)nR2 may form a spiro ring represented by the formula (30) below, together with the adjacent carbon atom (in the formula below, RRR represents a piperidyl group which may have substituents on the piperidine ring), (30)and R2 represents a benzothiazolyloxy group, quinolyloxy group, pyridyloxy group or the like. The present compound has an excellent bactericidal action against Mycobacterium tuberculosis, multi-drug-resistant Mycobacterium tuberculosis, and atypical acid-fast bacteria.
摘要:
The present invention provides a novel dihydrophenazine derivative represented by general formula (1), wherein R1 is a lower alkyl group or a hydroxy-lower alkyl group, which has antibacterial and bactericidal activities to tubercle bacilli and a wide range of atypical acid-fast bacilli; and a pharmaceutically acceptable salt thereof.
