Two radioiodinated analogs of benzoylcholine were investigated as possible myocardial-imaging agents. O-([2-125I]Iodobenzoyl)-choline and N-([2-125I]iodobenzoyl)cholamine were prepared by nucleophilic substitution of sodium [125I]iodide for stable iodine in O-(N,N]dimethylaminoethyl)-2-iodobenzoate and N-(N',N'-dimethylaminoethyl)-2-iodobenzamide, respectively, and by methylation with methyl iodide
研究了苯甲酰胆碱的两种放射性碘类似物作为可能的心肌显像剂。O-([2-125I]碘苯甲酰基)-胆碱和N-([2-125I]碘苯甲酰基)胆碱是通过将[125I]碘化钠亲核取代成O-(N,N]二甲基氨基乙基)-2中的稳定碘而制得的。 -碘代苯甲酸酯和N-(N',N'-二甲基氨基乙基)-2-碘代苯甲酰胺,并通过与甲基碘甲基化。确定每种化合物在小鼠中的体内分布作为时间的函数。用N-([2-125I]碘苯甲酰基)胆胺获得有利的心血和心肺比率。
