trypomastigote T. cruzi and their scaffold has been used as inspiration to design new derivatives with improved potency and chemical properties. We describe here the planning and microwave-irradiated synthesis of 26 isoxazole derivatives based on the structure of the lignans 1 and 2. In addition, the in vitro evaluation against culture trypomastigotes and intracellular amastigotes of T. cruzi and intracellular
恰加斯病和利什曼病是发展中国家中被忽视的热带病(NTD)。尽管有可用于治疗的药物,但是寻找新的有效疗法的努力仍在继续。天然木脂素Grandisin(1)和veraguensin(2)表现出对抗锥虫T. cruzi的活性,其脚手架已被启发用于设计具有更高效价和化学性质的新衍生物。我们在这里基于木脂素1和2的结构描述26种异恶唑衍生物的计划和微波辐射合成。此外,体外评估培养的锥虫和胞内变形虫的抗性。据报道,亚马逊乳杆菌和婴儿乳杆菌的克鲁氏锥虫和胞内变形虫。中合成的衍生物,化合物17(IC 50 = 5.26μM为克氏锥虫),29(IC 50 = 1.74μM为锥虫)和31(IC 50 = 1.13μM为锥虫和IC 50 = 5.08μM为亚马逊乳杆菌(L. amazonensis)是最活跃的,并且在其作用机理的初步研究中还针对抗克鲁斯氏锥虫的重组锥虫硫醚还原酶进行了评估。
