ligand exchange reaction with six-coordinated 99mTc(V) complex of N,N'-ethylenebis(acetylacetone imine), DM-PETS formed only one neutral 99mTc complex. 99mTc-PETS-L2, the more lipophilic complex of the two 99mTc-PETS, was obtained with a much higher yield than 99mTc-PETS-L1 by the ligand exchange reaction of PETS with the five-coordinated 99mTc(V) complex of glucoheptonate. In addition, while 99mTc-PETS-L2
使用新的双阴离子PETS衍生物3,3-二甲基戊烷-2对戊烷-2,4-二酮双-(N-甲基硫代半碳zone)(PETS)的两种中性tech- 99m(99mTc)配合物进行了进一步表征,4-二酮双(N-甲基硫代半碳酰胺)(DM-PETS),以及特征明确的2,2,9,9-四甲基-4,7-二氮杂-1,10-癸二硫醇(DADT)的99mTc络合物作为参考。PETS通过亚锡还原方法和与N,N'-亚乙基双(乙酰丙酮亚胺)六配位的99mTc(V)络合物的配位体交换反应生成了两个中性的99mTc络合物99mTc-PETS-L1和99mTc-PETS-L2 ),DM-PETS仅形成一种中性的99mTc复合物。99mTc-PETS-L2,这是两个99mTc-PETS中的亲脂性更高的复合物,通过PETS与5个配位的葡庚糖酸盐的99mTc(V)配合物进行配体交换反应,可得到比99mTc-PETS-L1高得多的收率。
