For determining 3-deoxyglucosone derivatives which are intermediate metabolites of the Maillard reaction in body fluids such as blood, urine, serum, plasma and the like in gas chromatography/mass spectrometry, ¹³C-labelled compounds or ¹⁴C-labelled compounds are useful as an internal standard substance. More specifically, 3-deoxyglucosone derivatives having the formula (I):
wherein *C is ¹³C or ¹⁴C, X is O or N-OR wherein R is Me, Et or H, and Y is SiMe₃ or SiMe₂tBu, and their production are provided. The measurement of 3-deoxyglucosone derivatives is useful in diagnosing diseases such as diabetes and diseases complicated with diabetes, including diabetic nephrosis, various renal disorders, renal insufficiency, metabolic diseases of carbohydrate and the like.
在气相色谱/质谱法中测定血液、尿液、血清、血浆等体液中作为 Maillard 反应中间代谢产物的 3-脱氧
葡萄糖酮衍
生物时,¹³C 标记的化合物或 ¹⁴C 标记的化合物可作为内标物质。更具体地说,具有式 (I) 的 3-脱氧
葡萄糖苷衍
生物:
其中 *C 是 ¹³C 或 ¹⁴C,X 是 O 或 N-OR,其中 R 是 Me、Et 或 H,Y 是 SiMe₃或 SiMe₂tBu。测量 3-脱氧
