the effect on bloodstream trypomastigotes of 16 new naphthoquinone analogues of β-lapachone modified in the pyran ring, aiming to find a new prototype with high trypanocidal activity. The new compounds presented a broad spectrum of activity, and five of them presented IC50/24 h in the range of 22–63 μM, whereas β-lapachone had a higher value of 391.5 ± 16.5 μM.
由克氏锥虫引起的南美锥虫病的可用化学疗法并不令人满意;因此,人们努力寻找治疗这种疾病的新药。在我们的实验室,我们分析了 16 种新型萘醌类似物在吡喃环上修饰的 β-拉帕醌对血流锥鞭毛体的影响,旨在寻找一种具有高杀锥虫活性的新原型。新化合物具有广谱活性,其中五种化合物的IC 50 /24 h 范围为22-63 μM,而β-拉帕酮的IC 50 /24 h 值更高,为391.5 ± 16.5 μM。
