The present invention is directed to labeled compounds, specifically
where each C* is selected from the group consisting of a carbon-12, i.e., 12C, or a carbon-13, i.e., 13C and at least one C* is 13C, R1 is selected from the group of C1-C4 lower alkyl and aryl, and X is selected from the group of —NR2R3 where R2 and R3 are each independently selected from the group of C1-C4 lower alkyl, alkoxy and aryl, —SR4 where R4 is selected from the group of C1-C4 lower alkyl, alkoxy and aryl, and —OR5 where R5 is selected from the group of C1-C4 lower alkyl, alkoxy and aryl with the proviso that when R1 is methyl then R5 is other than methyl, when R1 is ethyl then R5 is other than ethyl, and when R1 is benzyl then R5 is other than benzyl.
本发明涉及标记化合物,具体地说,其中每个C*选自群组,该群组由碳-12,即12C,或碳-13,即13C,至少有一个C*是13C,R1选自C1-C4低烷基和芳基群组,X选自—NR2R3群组,其中R2和R3分别独立选自C1-C4低烷基、烷氧基和芳基群组,—SR4群组,其中R4选自C1-C4低烷基、烷氧基和芳基群组,以及—OR5群组,其中R5选自C1-C4低烷基、烷氧基和芳基群组,但有一个条件,即当R1为甲基时,R5不是甲基,当R1为乙基时,R5不是乙基,当R1为苄基时,R5不是苄基。
