inactive on trypanothione reductase. Two derivatives 6 and 12 of this compound, one symmetrical and one dissymmetrical, were synthesized via a reductive amination reaction, to prepare affinity chromatography columns, which allowed us to isolate three parasitic proteins. Among these, the major ligand 6- and 12-binding protein having an apparent molecular weight of 52 kDa has been identified as the thiol-disulfide
一系列对称取代的1,4-双(3-氨基丙基哌嗪)中最有效的锥虫杀虫剂对克氏锥虫锥虫的IC50值为5 microM,对锥虫硫磷还原酶没有活性。通过还原胺化反应合成了该化合物的两种衍生物6和12,一种是对称的,一种是不对称的,以制备亲和色谱柱,可分离出三种寄生蛋白。其中,表观分子量为52 kDa的主要配体6和12结合蛋白已被鉴定为巯基二硫键氧化还原酶Tc52,以前在克鲁斯锥虫中有特征。
