The present invention provides pyrazole derivatives represented by the general formula:
wherein R
1
represents H, an optionally substituted C
1-6
alkyl, etc.; one of Q and T represents a group selected from the following:
, and the other represents -Z-Ar wherein Z represents —O—, —S—, etc.; Ar represents an optionally substituted C
6-10
aryl, etc.; R represents an optionally substituted C
3-8
cycloalkyl, an optionally substituted C
6-10
aryl, etc., pharmaceutically acceptable salts thereof, and prodrugs thereof, which exhibit an excellent inhibitory activity in human sodium/glucose cotransporter (SGLT) and are useful as agents for the prevention, inhibition of progression or treatment of a disease associated with the excess uptake of at least a kind of carbohydrates selected from glucose, fructose and mannose (diabetes, postprandial hyperglycemia, impaired glucose tolerance, diabetic complications, etc.), and pharmaceutical compositions containing the same, medicinal uses thereof and intermediates for production therefor.
本发明提供了由下式表示的吡唑衍生物:
