Previously, thiazoles resulted in an increase in anti-T. cruzi activity in comparison to thiosemicarbazones. Here, we report the structural planning, synthesis and anti-T. cruzi evaluation of new thiazoles derivatives (3a-m and 4a-m), designed from molecular hybridization associated with non-classical bioisosterism. By varying substituents attached to the phenyl and thiazole rings, substituents were
由运动质体原生动物寄生虫克氏锥虫引起的恰加斯病仍然是疾病和过早死亡的重要原因,据估计全世界有600万至700万人受到感染。尽管化学疗法的选择受到限制,但会带来严重的问题,例如疗效低和毒性高。T. cruzi对噻唑很敏感,这使得这类化合物对药物开发具有吸引力。以前,噻唑导致抗T的增加。与硫代半脲相比,克鲁兹活性更高。在这里,我们报告结构规划,综合和反T。Cruzi评价新的噻唑衍生物(3a-m和4a-m),该衍生物是通过与非经典生物等排相关的分子杂交而设计的。通过改变连接在苯基和噻唑环上的取代基,可以观察到取代基保留,增强或大大提高其抗T能力。与相应的硫半脲相比,其具有克鲁索活性。在大多数情况下,吸电子取代基(如溴,3,4-二氯和硝基)大大提高了抗寄生虫活性。具体来说,鉴定出了新的噻唑类,它们抑制了近鞭毛象的增殖,并且对锥鞭毛象有毒,而不会影响巨噬细胞的生存能力。还评估了这些化合物对克鲁萨因的
