The present invention provides glucopyranosyloxypyrazole derivatives represented by the general formula:
wherein R represents a hydrogen atom, a lower alkyl group or a group forming a prodrug; one of Q and T represents a group represented by the general formula:
(wherein P represents a hydrogen atom or a group forming a prodrug), while the other represents a lower alkyl group or a halo(lower alkyl) group; R
2
represents a hydrogen atom, a lower alkyl group, a lower alkoxy group, a lower alkylthio group, a halo (lower alkyl) group or a halogen atom; and with the proviso that P does not represent a hydrogen atom when R represents a hydrogen atom or a lower alkyl group, or pharmaceutically acceptable salts thereof, which exert an inhibitory activity in human SGLT2 and have an improved oral absorption, and therefore are useful as agents for the prevention or treatment of a disease associated with hyperglycemia such as diabetes, diabetic complications or obesity, and pharmaceutically acceptable salts thereof, and pharmaceutical uses thereof.
本发明提供了由下式表示的
葡萄糖吡唑基氧基
吡唑衍
生物:
其中R表示氢原子、低碳基或形成前药的基团;Q和T中的一个表示由下式表示的基团:
(其中P表示氢原子或形成前药的基团),而另一个表示低碳基或卤代(低碳基)基团;R2表示氢原子、低碳基、低碳氧基基团、低碳
硫基基团、卤代(低碳基)基团或卤素原子;但是在R表示氢原子或低碳基团时,P不表示氢原子。此类衍
生物在人类SGLT2中具有抑制活性,并具有改善口服吸收,因此可用作预防或治疗与高血糖有关的疾病,如糖尿病、糖尿病并发症或肥胖症的药物,以及其医药用途的药物可接受的盐。
