This paper describes the synthesis and in vitro biological activities of imidazolidine and hexahydropyrimidine
derivatives against bacteria (Escherichia coli, Staphylococcus aureus and Mycobacterium tuberculosis) and Leishmania
protozoa. Out of sixteen heterocyclic derivatives tested, none were cytotoxic against mammalian cells. The compounds
showed significant bacterial effects and leishmanicidal activity. Compounds 4a and 4c were active against S. aureus and
E. coli, respectively. Compounds 3a-3f, 4h and 4i presented promising results against M. tuberculosis, with MIC values
ranging from 12.5 to 25.0 μg/mL, comparable to the “first and second line” drugs used to treat tuberculosis. Compounds
4a, 4c and 4e were active against L major. Three of them were structurally characterized by single-crystal X-ray diffraction.
本文介绍了咪唑烷和六氢嘧啶衍生物的合成及其对细菌(大肠杆菌、金黄色葡萄球菌和结核分枝杆菌)和利什曼原虫的体外生物活性。在测试的 16 种杂环衍生物中,没有一种对哺乳动物细胞具有细胞毒性。这些化合物具有明显的杀菌作用和杀利什曼原虫活性。化合物 4a 和 4c 分别对金黄色葡萄球菌和大肠杆菌具有活性。化合物 3a-3f、4h 和 4i 对结核杆菌有很好的疗效,其 MIC 值介于 12.5 至 25.0 μg/mL 之间,与用于治疗结核病的 "一线和二线 "药物相当。化合物 4a、4c 和 4e 对大肠杆菌具有活性。单晶 X 射线衍射对其中三种化合物进行了结构表征。
