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衍生物:
其中,R表示氢原子,低级烷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),而另一个表示低级烷基或卤代(低级烷基)基团;R2表示氢原子,低级烷基,低级烷氧基,低级烷基硫基,卤代(低级烷基)基团或卤素原子;但要注意,当R表示氢原子或低级烷基时,P不表示氢原子。本发明的衍生物在人体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,以及其药学上可接受的盐和药物用途。
