  7-Substituted 2-Nitro-5,6-dihydroimidazo[2,1-b][1,3]oxazines: Novel Antitubercular Agents Lead to a New Preclinical Candidate for Visceral Leishmaniasis

  摘要：

  Within a backup program for the clinical investigational agent pretomanid (PA-824), scaffold hopping from delamanid inspired the discovery of a novel class of potent antitubercular agents that unexpectedly possessed notable utility against the kinetoplastid disease visceral leishmaniasis (VL). Following the identification of delamanid analogue DNDI-VL-2098 as a VL preclinical candidate, this structurally related 7 substituted 2-nitro-5,6-dihydroimidazo [2,1-b][1,3]oxazine class was further explored, seeking efficacious backup compounds with improved solubility and safety. Commencing with a biphenyl lead, bioisosteres formed by replacing one phenyl by pyridine or pyrimidine showed improved solubility and potency, whereas more hydrophilic side chains reduced VL activity. In a Leishmania donovani mouse model, two racemic phenylpyridines (71 and 93) were superior, with the former providing >99% inhibition at 12.5 mg/kg (b.i.d., orally) in the Leishmania infantum hamster model. Overall, the 7R enantiomer of 71 (79) displayed more optimal efficacy, pharmacokinetics, and safety, leading to its selection as the preferred development candidate.

  2-nitroimidazo[2,1-b][1,3]oxazines were previously shown to exhibit potent antileishmanial and antitrypanosomal activities, culminating in a new clinical investigational drug for visceral leishmaniasis (DNDI-0690). To offset development risks, we continued to seek further leads with divergent candidate profiles, especially analogues possessing greater aqueous solubility. Starting from an efficacious monoaryl

  抗结核病7-取代的 2-硝基咪唑并[2,1- b ][1,3] 恶嗪先前已被证明具有有效的抗寄生虫和抗锥虫活性，最终产生了一种用于治疗内脏利什曼病的新临床研究药物 (DNDI-0690)。为了抵消开发风险，我们继续寻找具有不同候选特征的进一步线索，特别是具有更大水溶性的类似物。从一种有效的单芳基衍生物开始，首先探索了用新型胺、酰胺和脲官能团替代侧链醚键；前一种替代物在体外和体内均具有良好的耐受性但引起溶解度的微小变化（通过不太稳定的苄胺除外），而后一组导致溶解度显着提高（高达 53 倍），但抗虫效力降低至少 10 倍。最终，我们发现O-氨基甲酸酯66在内脏利什曼病小鼠模型中提供了更高的溶解度、合适的代谢稳定性、出色的口服生物利用度 (100%) 和强大的体内功效（25 mg 时寄生虫负荷减少 97% /公斤）。
