medical need. These parasites are unable to synthesize the purine ring de novo, and therefore rely on purine salvage to meet their purine demand. Evaluating purine nucleoside analogs is therefore an attractive strategy to identify antikinetoplastid agents. Several anti-Trypanosoma cruzi and anti-Trypanosoma brucei 7-deazapurine nucleosides were previously discovered, with the removal of the 3′-hydroxyl
运动质体寄生虫是被忽视的热带病的病原体,医疗需求未得到满足。这些寄生虫无法从头合成嘌呤环,因此只能依靠嘌呤挽救来满足其嘌呤需求。因此,评价嘌呤核苷类似物是鉴定抗动素体药物的一种有吸引力的策略。几种抗克氏锥虫和抗布鲁氏锥虫先前已发现7-脱氮嘌呤核苷,并去除了3'-羟基,从而显着提高了活性。因此,在这项工作中,我们决定评估在7-脱氮嘌呤核苷中引入3'-氟取代基对抗动素体活性的影响。因此,我们合成了两个系列的3'-脱氧-3'- fluororibofuranosyl和3'-脱氧-3' - fluoroxylofuranosyl核苷包括7-脱氮腺嘌呤和次黄嘌呤碱,并测定这些对于抗寄生虫活性。发现了几种对克鲁斯氏锥虫和布鲁氏菌具有有效活性的类似物,表明3'-位的氟原子是发现抗寄生虫核苷的有前途的修饰。
