some compounds and to the B ring in others, with additional substituents placed on the chalcone moiety. The present aim was to evaluate the effect of the substitution pattern on leishmanicidal and trypanocidal activity. When tested at a single concentration, the compounds exerting a metabolic inhibition close to or exceeding 50% for Leishmania mexicana were 11, 17 and 12, and for Trypanosoma cruzi were
除其他问题外,可用于治疗利什曼病和美国锥虫病的可用药物具有高毒性和多种副作用。迫切需要更有效和毒性更小的治疗。合成并表征了一系列含有异戊烯氧基或香叶基氧基取代基的查耳酮。在某些化合物中,每个取代基均连接至A环,而在另一些化合物中,均连接至B环,查尔酮部分上还带有其他取代基。本发明的目的是评估取代模式对利什曼和锥虫活性的影响。当在单一浓度下测试,施加代谢抑制接近或超过50%的所述化合物墨西哥利什曼原虫是11,17和12和用于克氏锥虫是11,17,15和26。一旦确定选择性指数(SI = IC 50 / CC 50),这些值分别为80.9,1.24和55.12为11,17和12(分别)与墨西哥利什曼原虫,和75.1,1.43,27.36和33.52为11,17,15和26(分别)与T. cruzi相比。结构异构体11和17对墨西哥乳杆菌均具有活性和克氏锥虫菌株,尽管17的较高的细胞毒活性导致较
