(+)-7-deaza-5'-noraristeromycin (1), as an L-like analogue of aristeromycin, possessed meaningful anti-trypanosomal properties has prompted a search of other 7-deazapurines with similar or improved anti-trypanosomal responses. In that direction a series of pyrazolo[3,4-d]pyrimidines (that is, 8-aza-7-deaza-5'-noraristeromycin derivatives, 2-11) related to 1 have been prepared. These derivatives were evaluated
最近的观察表明(+)-7-deaza-5'-noraristeromycin(1)作为Aristeromycin的L样类似物,具有有意义的抗锥蛋白特性,这促使人们寻找其他具有相似或改进的抗胰蛋白酶作用的7-deazapurines。锥虫反应。在该方向上,已经制备了与1有关的一系列吡唑并[3,4-d]嘧啶(即8-氮杂-7-脱氮杂5'-诺拉霉素霉素衍生物2-11)。针对体外生长的布鲁氏锥虫和罗氏锥虫的血流形式对这些衍生物进行了评估。在这些化合物中,母体L状衍生物2(IC50 40-70 microM)的效价比1(IC50 0.165-5.3 microM)弱,而D状类似物3则无活性,这与之前用7- deaza-5'-诺拉霉素。有趣的是,有些适度的活动(IC50 12.2-16。
