This work describes the synthesis, structural characterization, trypanocide and cytotoxic evaluation of α,β-unsaturated ketones derived from eugenol and analogues. Among the synthesized compounds, the cyclopentanonic/dihydroeugenol derivative 12 was active against amastigote forms of Trypanosoma cruzi at 5.2 nM (700 times more potent than benznidazole) and represents a potential hit for future structural
这项工作描述了来自丁香酚和类似物的 α,β-不饱和酮的合成、结构表征、杀锥虫和细胞毒性评价。在合成的化合物中,环戊酸/二氢丁香酚衍生物12在 5.2 nM(比苯并硝唑的效力高 700 倍)时对克氏锥虫的无鞭毛体形式具有活性,并且代表了未来结构优化以降低其毒性的潜在影响。还针对健康人和四种癌细胞系对所有化合物进行了评估,衍生物10对三种癌细胞的活性比多柔比星更强(IC 50值在 2.03-23.51 µM 之间),并且在考虑人体细胞时显示出更高的选择性指数。衍生物14对两种癌细胞也比阿霉素更有效和更具选择性(IC 50值在 4.71–8.86 µM 之间)。
