摘要
研究了在CH3OH,C2H5OH,H2O3种溶剂体系中99mTcO4-,乙酰苯肼(PhNHNHCOCH3,APH)、还原剂(Sn2+、三苯基膦、三(间磺酸钠)苯基膦)与配体Et2NCS2Na的反应,以制备含[99mTcVN—Ph]3+核的新配合物[TcVCl(NPh)(Et2NCS2)2]。用放射性纸层析、薄层色谱及放射性纸电泳对反应产物进行了检测,并测定了不同条件下产物在环己烷/水、正辛醇/水中的分配系数,得到了制备含[99mTcVN—Ph]3+核的配合物的相关条件,还进一步研究了这种配合物的动物分布。结果是该配合物在正常小白鼠体内不稳定,心和脑的摄取率低。
Reactions of 99mTcO 4 -,acetylphenylhydrazine (PhNHNHCOCH 3),reducing agent (Sn2+,Triphenylphosphine,Tris(m sulfophenyl) phosphine) and ligand Et 2NCS 2Na in CH 3OH,C 2H 5OH and H 2O solvent systems were studied.The final new product 99mTc VCl(NPh)(Et 2NCS 2) 2 was characterized by paper chromatography,thin layer chromatography and paper electrophoresis,and also partition coefficients in cyclohexane/water and n octanol/water systems were measured.The biodistribution of this complex was also determined,showing that the complex does not accumulate in heart,nor brain.
