The present invention provides pyrazole derivatives represented by the general formula:
wherein R
1
represents H, an optionally substituted C
1-6
alkyl group etc.; one of Q and T represents a group selected from the following groups:
and the other represents —(CH
2
)
n
—Ar wherein Ar represents an optionally substituted C
6-10
aryl group or an optionally substituted C
1-9
heteroaryl group; and n represents an integral number from 0 to 2, an optionally substituted C
1-6
alkoxyl group, an optionally substituted amino group, an optionally substituted C
2-9
heterocycloalkyl group or an optionally substituted heterocycle-fused phenyl group; R represents an optionally substituted C
3-8
cycloalkyl group, an optionally substituted C
6-10
aryl group etc., pharmaceutically acceptable salts thereof or prodrugs thereof, which exhibit an excellent inhibitory activity in human 1,5-anhydroglucitol/fructose/mannose transporter 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 or a disease associated with hyperglycemia (e.g., diabetic complications, diabetes, etc.), and pharmaceutical compositions comprising the same, pharmaceutical uses thereof, and intermediates for production thereof.
本发明提供了由下式表示的吡唑衍生物:其中,R1代表H、可选取代的C1-6烷基等;Q和T中的一个代表以下基团之一:另一个代表—(CH2)n—Ar,其中Ar代表可选取代的C6-10芳基基团或可选取代的C1-9杂环芳基基团;n表示0至2的整数、可选取代的C1-6烷氧基基团、可选取代的氨基基团、可选取代的C2-9杂环烷基基团或可选取代的杂环融合苯基团;R代表可选取代的C3-8环烷基基团、可选取代的C6-10芳基基团等,以及其药学上可接受的盐或前药,其在人类1,5-脱水葡萄糖/果糖/甘露糖转运体中表现出优异的抑制活性,并且可用作预防、抑制进展或治疗与葡萄糖、果糖和甘露糖中至少一种的过度摄取或高血糖相关的疾病的药物(例如糖尿病并发症、糖尿病等),以及包含它们的制药组合物、制药用途和其制备的中间体。
