摘要:
An object of the present invention is to provide novel carbazole derivatives, solvates thereof, or pharmaceutically acceptable salts thereof having an excellent adipose tissue weight reducing effect, hypoglycemic effect, and hypolipidemic effect, which are useful as a preventive and/or therapeutic agent for fatty liver, obesity, lipid metabolism abnormality, visceral adiposity, diabetes, hyperlipemia, impaired glucose tolerance, hypertension, non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, and the like.The above-mentioned object can be achieved by carbazole derivatives, solvates thereof, or pharmaceutically acceptable salts thereof, wherein the carbazole derivatives are represented by the following general formula (I): (In the formula (I), the ring A represents phenyl group or the like; X represents —O— or the like; Y represents ═N— or the like; a and b represent methylene group or the like; both V and Z represent —O— or the like; W represents a C1-C10 alkylene group whose 1 or 2 hydrogen atoms may be substituted by a phenyl group or a C1-C6 alkyl group; 1,2-phenylene group; 1,3-cyclohexyl group; or the like; R1 represents methyl group or the like; R2 represents methoxy group or the like; and R3 represents carboxy group or the like.).
摘要:
A benzimidazole derivative of formula (1): (wherein R represents a hydrogen atom or a methoxy group, and n is 0 or 1) or a salt thereof; and a medicament containing the same. The compounds of the present invention, due to minimized difference in therapeutic effect between subjects, which difference would otherwise be derived from different CYP2C19 activity from subject to subject, ensure that all patients can enjoy proper therapeutic effects at the same dose of the drug. Also, the compounds of the invention have low risk of drug interaction caused by induction of CYP1A family member enzymes, as well as low risk of development of cancer, and thus is useful as a remedy for peptic ulcer, reliably providing therapeutic effects with safety.
