at the structure-based design of drugs against sleeping sickness, analogs of 2'-deoxy-2'-(3-methoxybenzamido)adenosine (1) were synthesized and tested to establish structure-activity relationships for inhibiting glycosomal glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Compound 1 was recently designed using the NAD:GAPDH complexes of the human enzyme and that of Trypanosoma brucei, the causative
在继续进行旨在针对睡眠病的药物的基于结构的设计的项目时,合成并测试了2'-脱氧-2'-(3-甲氧基苯甲酰胺基)腺苷(1)的类似物,并建立了抑制糖体的构效关系。 3-磷酸甘油醛脱氢酶(GAPDH)。最近使用人类酶和昏睡锥虫(Trypanosoma brucei)的NAD:GAPDH复合物设计了化合物1。为了利用寄生虫酶的Val 207来开发额外的疏水结构域,合成了几种新的2'-酰胺基-2'-脱氧腺苷。与1相比,其中一些显示出抑制活性的有趣改善。碳环或无环类似物显示出明显的活性损失,说明了典型(C-2' -endo)核糖部分的起皱。我们还描述了一对化合物的合成,该化合物结合了2-和8-取代的腺嘌呤部分对效能的有益作用与2'-酰胺基对选择性的有益作用。不幸的是,在两种情况下,IC50值都证明了这些组合修饰的不相容性。最后,在5'-脱氧腺苷上引入疏水的5'-氨基基团显着增强了对原生动物酶的抑制
