result in many significant side effects. The study describes the synthesis and biological evaluation of 3,5-disubstituted isoxazoles. Isoxazoles were obtained by reaction of flavones and hydroxylamine and either alkylated at the free hydroxyl group and/or nitrated at the isoxazole ring. These compounds were evaluated for their in vitro anti-Trypanosoma cruzi activity against trypomastigote and amastigote
恰加斯病被列入被忽视的热带病清单,并且是21个拉丁美洲国家的地方病。目前可用于治疗南美锥虫病的两种药物是尼富替莫和苯尼达唑,两者均导致许多明显的副作用。该研究描述了3,5-二取代异恶唑的合成和生物学评估。通过黄酮与羟胺反应获得异恶唑,并在游离羟基处烷基化和/或在异恶唑环上进行硝化。评估了这些化合物的体外抗锥虫和锥虫的抗锥虫和锥虫形式的活性,所述锥虫和锥虫感染了克氏杆菌感染的细胞谱系。苯并咪唑用作体外测定的参考化合物,哺乳动物L929细胞用于评估细胞毒性。
