procedure for high level tritium labelling at the C2-H position of adenosine 5'-triphosphate ([2- 3 H]-ATP, 1), based on the tritiodehalogenation reaction of 2-bromoadenosine 5'-triphosphate (2) has been elaborated. This precursor was prepared in a six-step synthesis from guanosine. The tritiodehalogenation of (2) for three hours over palladium oxide in phosphate buffer yielded tritium labelled ATP with
基于 2-溴腺苷 5'-三磷酸 (2) 的三硫脱卤反应,在 5'-三磷酸腺苷 ([2- 3 H]-ATP, 1) 的 C2-H 位置进行高水平氚标记的程序已经详述。这种前体是通过六步合成从鸟苷中制备的。(2) 在磷酸盐缓冲液中用氧化钯进行三小时脱卤反应,以良好的化学产率产生具有高比活性的氚标记的 ATP。
