Acivicin analogues with an increased affinity for CTP synthetase (CTPS) were designed as potential new trypanocidal agents. The inhibitory activity against CTPS can be improved by increasing molecular complexity, by inserting groups able to establish additional interactions with the binding pocket of the enzyme. This strategy has been pursued with the synthesis of α‐amino‐substituted analogues of Acivicin
对 CTP 合成酶 (CTPS) 具有更高亲和力的 Acivicin 类似物被设计为潜在的新型杀锥虫剂。通过增加分子复杂性,插入能够与酶结合口袋建立额外相互作用的基团,可以提高对 CTPS 的抑制活性。这种策略已经通过合成 Acivicin 的 α-氨基取代类似物和 N1 取代的吡唑啉衍生物来实现。一般来说,酶活性与此处研究的衍生物的体外抗锥虫病功效之间存在直接相关性。然而,这不能作为一般规则,因为其他重要因素可能会起作用,特别是分子吸收/扩散到锥虫的能力。
