library of 62 compounds [i.e. alkane, diphenyl, and azaalkane bisguanidines and bis(2-aminoimidazolines)], which were chosen for their structural similarity to the trypanocidal agents synthalin (1,10-decanediguanidine) and 4,4'-diguanidinodiphenylmethane and the polyamine N(1)-(3-amino-propyl)propane-1,3-diamine, respectively, is reported. The original synthetic procedure for the preparation of 21 of these
在内部筛选62种化合物(即烷烃,二苯基和氮杂烷双胍和双(2-氨基咪唑啉))的库中针对布氏锥虫的锥虫杀虫活性,选择这些化合物的原因是其与锥虫杀虫剂合成素的结构相似性据报道,分别有(1,10-癸烷二胍)和4,4'-二胍二苯甲烷和多胺N(1)-(3-氨基-丙基)丙烷-1,3-二胺。还报道了制备21种这些化合物的原始合成方法。大多数化合物显示出较低的微摩尔抗锥虫活性,其中五种对寄生虫具有纳摩尔抑制作用:1,9-壬二胍(1c),1,12-十二烷二胍(1d),4,4'-双[1,3-双(叔丁氧羰基)-2-咪唑啉亚胺基]二苯胺(28a),4,4'-双(4,5-二氢-1H-2-咪唑基氨基)二苯胺(28b)和4,4′-二胍基二苯胺(32b)。那些表现出出色的体外活性以及对寄生虫具有高选择性的分子[例如1c(IC(50)= 49 nM; SI> 5294),28b(IC(50)= 69 nM; SI = 3072),32b
