The present invention provides a method for the synthesis of radioiodinated compounds which is advantageous over prior art methods. Using a hydrazine or an aminoxy in place of a primary amine for indirect radioiodination facilitates a much quicker reaction thus reducing reaction time and increasing the yield. In addition, where there are primary amines in the molecule to be radioiodinated, such as the N-terminus of a peptide or lysine residues, reaction at the hydrazine or aminoxy is greatly favoured.
本发明提供了一种合成放射性
碘化合物的方法,相比先前的方法具有优势。使用
肼或
氨氧基代替一级胺来进行间接放射性
碘化反应,可以加快反应速度,从而减少反应时间并增加产量。此外,如果分子中存在一级胺,例如肽的N-末端或赖
氨酸残基,则在
肼或
氨氧基处进行反应的倾向性大大增加。
