brucei infections in mice. A wide range of ED50 values was observed among 5-substituted derivatives of 4. The 5-amino analogue 5 and 5-acetamido analogue 6 were about twice as active as 4. 1,3,5-Triacetylbenzene tris(guanylhydrazone) (12) was about 9 times as active as 4 and was approximately one-half as active as the currently used trypanocide diminazene aceturate in this test system. Other 5-derivatives
基于1,3-二乙酰基苯双guan胍(4)和2,6-二乙酰基吡啶双(胍(17)的抗胰管体活性,许多取代的和杂环的1,3-亚芳基二酮双guan胍是制备并测试了针对小鼠布鲁氏锥虫感染的方法。在4的5个取代衍生物中观察到很宽的ED50值。5-氨基类似物5和5-乙酰氨基类似物6的活性约为4的两倍。1,3,5-三乙酰苯三(guan)(12)在该测试系统中,其活性约为4的9倍,活性约为目前使用的锥虫二甲基二氮杂苯乙酸乙酸盐的一半。其他5个衍生物的活性等于或低于母体化合物4的活性。三个新的杂环类似物的活性均低于2,6-二乙酰基吡啶衍生物17和苯衍生物4。邻位hydrhydr侧链的环取代总是不利于活性。侧链同系物1,3-二戊酰基苯双(胍基hydr)和1,3-二乙酰基苯双(2-咪唑啉-2-基hydr)基本上没有活性。
