synthesized by rhodium-catalyzed C-H bond activation and palladium-catalyzed cross-coupling reactions, were evaluated against bloodstream trypomastigotes of T. cruzi. We have identified fifteen compounds with IC50/24 h values of less than 2 μM. Electrochemical studies on A-ring functionalized naphthoquinones were also performed aiming to correlate redox properties with trypanocidal activity. For instance
通过铑催化的CH键活化和钯催化的交叉偶联反应合成的三十四个含卤素和硒的醌,对克氏锥虫的血色伪鞭毛体进行了评估。我们确定了15种化合物的IC 50/24 h值小于2μM。还进行了A环官能化萘醌的电化学研究,旨在将氧化还原特性与锥虫杀灭活性联系起来。例如(E)-5-styryl-1,4-naphthoquinone 59和5,8-diiodo-1,4-naphthoquinone 3其潜在活性是标准药物苯甲硝唑的约50倍,是有待进一步研究的潜在衍生物。这些化合物代表了在南美锥虫病治疗中有用的强大新药。
