families of N-oxide containing heterocycles were evaluated as in vitro growth inhibitors of T. cruzi. Both families of heterocycles were selected from our in-house library of compounds as analogues of active anti-T. cruzi N-oxide containing heterocycles. Derivatives from pyrimido[1,2-a]quinoxaline 6-oxide family were poorly active at the assayed doses. However, phenazine 5,10-dioxide derivatives displayed
评价了两个不同的含N-氧化物的杂环家族作为克鲁维酵母的体外生长抑制剂。这两个杂环家族均选自我们内部的化合物库,作为活性抗T的类似物。含Cruzi N-氧化物的杂环。在测定的剂量下,嘧啶并[1,2-a]喹喔啉6-氧化物家族的衍生物活性较弱。然而,吩嗪5,10-二氧化物衍生物表现出良好至优异的抗T。克鲁兹活动。反T。吩嗪衍生物的cruzi活性与取代基的电子描述符sigma(p)(-)相关。衍生物19、20和23是对原生动物最具细胞毒性的化合物,并成为进一步结构修饰的极好选择。
