Novel nucleoside analogues named "triazoxins" were synthesized. Of these, two analogues were found to be highly effective against Giardia lamblia, an intestinal parasite and a major cause of waterborne infection, worldwide. While compound 7 reduced the growth of trophozoites in culture (IC50, ~5 μM), compound 21 blocked the in vitro cyst production (IC50 ~5 μM). Compound 21 was also effective against
合成了名为“三唑嗪”的新型核苷类似物。其中,有两种类似物被发现对对抗兰氏贾第鞭毛虫非常有效,兰氏贾第鞭毛虫是一种肠道寄生虫,也是全世界水传播感染的主要原因。化合物 7 减少培养物中滋养体的生长(IC50,~5 μM),而化合物 21 则阻断体外包囊生成(IC50~5 μM)。化合物 21 对滋养体也有效(IC50,~36 μM)。第三种类似物(化合物 8)对滋养体(IC50,~36 μM)和包囊(IC50,~20 μM)均有效,尽管浓度较高。因此,三唑嗪类似物是独特的并且表现出针对贾第鞭毛虫的形态学(即,长孢子或包囊)特异性作用。
