(Discrete Typing Units). Therefore, new drugs to treat this disease are necessary. Thiazole compounds have been described as potent trypanocidal agents. Here we report the structural planning, synthesis and anti-T. cruzi evaluation of a new series of 1,3-thiazoles (7–28), which were designed by placing this heterocycle instead of thiazolidin-4-one ring. The synthesis was conducted in an ultrasonic bath
恰加斯病是美洲大陆最严重的健康问题之一。苯并硝唑(BDZ)和尼呋替莫(NFX)是唯一获准用于治疗的药物,除了在T. cruzi DTU(Discrete Typing Units)之间的易感性不同之外,在慢性阶段还表现出强烈的副作用和无效性。因此,治疗这种疾病的新药是必要的。噻唑化合物已被描述为有效的锥虫杀虫剂。在这里,我们报告了一系列新的1,3-噻唑类化合物的结构规划,合成和抗T. cruzi评估(7–28),这是通过放置该杂环而不是噻唑烷丁4一环来设计的。在室温下在超声浴中以2-丙醇为溶剂进行合成。通过改变连接在苯基和噻唑环上的取代基,观察到取代基保留,增强或大大提高了它们的抗克鲁维氏球菌活性。在一些情况下,在噻唑(化合物的5位甲基9,12和23)增加的杀锥虫属性。苯基交换为吡啶基杂环导致活性增加,从而产生最有效的抗锥虫病菌形式的化合物(14,IC 50trypo = 0.37μM)。
