Zusammenfassung: | A pyrazole derivative represented by the general formula (I) [wherein R1 is H, optionally substituted C1-6 alkyl, etc.; either of Q and T is the group of the formula (II) or the formula (III) and the other is optionally substituted C1-6 alkyl, etc.; R2 is H, halogeno, OH, optionally substituted C1-6 alkyl, etc.; X is a single bond, O, or S; Y is optionally substituted C1-6 alkylene, etc.; Z is -RB, -CORC, etc. (RB is optionally substituted C1-6 alkyl, etc.; and RC is optionally substituted C1-6 alkyl, etc.); R4 is H, optionally substituted C1-6 alkyl, etc.; and R3, R5, and R6 each is H, halogeno, etc.], a pharmacologically acceptable salt of the derivative, or a prodrug of either. They have excellent human SGLT1 inhibitory activity and are useful as a preventive or therapeutic agent for diseases attributable to hyperglycemia such as diabetes, impaired glucose tolerance, fasting blood sugar abnormality, complications of diabetes, and obesity and for diseases attributable to an increased blood galactose level such as galactosemia.
