This work reports on the development of an efficient and ecofriendly ultrasound assisted method for the high yield synthesis (70.0-94.0%) of eighteen oxyalkylated derivatives of 2',4'-dihydroxychalcone. Synthesized compounds were subjected to in vitro biological assays against HT-29 (colorectal), MCF-7 (breast), and PC-3 (prostate) human tumor cell lines, these cell lines are among the ten most aggressive
这项工作报告了一种高效,环保的超声辅助方法的开发,该方法可以高产率地合成18种2',4'-二羟基查耳酮的烷氧基化衍生物(70.0-94.0%)。对合成的化合物进行了针对HT-29(结肠直肠),MCF-7(乳腺癌)和PC-3(前列腺)人类肿瘤细胞系的体外生物学分析,这些细胞系是世界上诊断出的十种最具侵袭性的恶性肿瘤之一。细胞毒性评估表明,四种合成的化合物对MCF-7(IC 50 = 8.4–34.3μM)和PC-3(IC 50 = 9.3-29.4μM)表现出中等至非常高的毒性,与5-氟尿嘧啶(IC 5016.4–22.3μM)。相同的化合物仅对HT-29(IC 50 15.3-36.3μM)具有中等活性,接近柔红霉素(IC 50 15.1μM )。接着,尽管化合物的选择性指数(SI)较弱,但化合物18对癌细胞显示出显着的选择性细胞毒性活性(5.8-10.57)。除此以外,大多数化合物显着降
