A method for simply measuring a 1,2-dicarbonyl derivative in multiple specimens is provided, which comprises converting a 1,2-dicarbonyl derivative to a pyrazine derivative represented by the formula (I):
wherein R1 and R2 independently represent a hydrogen atom, a methyl group, a hydroxymethyl group, a hydroxyethyl group, a dihydroxyethyl group, a dihydroxypropyl group, a trihydroxypropyl group, or a trihydroxybutyl group, A represents a group that binds to the pyrazine ring to form a 6-membered aromatic hydrocarbon group, a 5- or 6-membered aromatic heterocyclic group, or a 5- or 6-membered alicyclic hydrocarbon group, and R3 represents a linking residue, wherein said 5-membered ring formed by A may have 1 or 2 substituents and said 6-membered ring may have 1 to 3 substituents, in addition to R3 and measuring the pyrazine derivative by an immunological method using an antibody that recognizes the pyrazine derivative.
提供了一种简单测量多个标本中1,2-二羰基衍生物的方法,该方法包括将1,2-二羰基衍生物转化为由式(I)表示的吡嗪衍生物,其中R1和R2分别表示氢原子,甲基,羟甲基,羟乙基,二羟乙基,二羟丙基,三羟丙基或三羟丁基,A表示结合到吡嗪环形成6-成员芳香烃基,5-或6-成员芳香杂环基或5-或6-成员脂环烃基的基团,R3表示连接残基,其中由A形成的5-成员环可能具有1或2个取代基,6-成员环可能具有1到3个取代基,除了R3之外,通过使用识别吡嗪衍生物的抗体的免疫学方法测量吡嗪衍生物。
