describe novel acetohydroxamic acid derivatives with potent activity against cultured bloodstream-form Trypanosoma brucei and selectivity indices of >1000. These analogues were derived from conformationally constrained, lipophilic, spiro carbocyclic 2,6-diketopiperazine (2,6-DKP) scaffolds by attaching acetohydroxamic acid moieties to the imidic nitrogen. Optimal activity was achieved by placing benzyl
我们描述了新的乙酰异羟肟酸衍生物,其对培养的血流型布氏锥虫具有强效活性,选择性指数大于 1000。这些类似物源自构象受限的亲脂性螺碳环 2,6-二酮哌嗪 (2,6-DKP) 支架,通过将乙酰异羟肟酸部分连接到亚胺氮。通过将苄基与 2,6-DKP 核心的碱性氮相邻放置来实现最佳活性。S-对映异构体7d是对布氏木霉(IC 50 = 6.8 nM) 和克氏木霉(IC 50 = 0.21 μM)最具活性的衍生物。
