of biological activities. In this study, 5-O-acyl derivatives of quercetin were synthesised and assessed for their antiproliferative activity against the HCT116 colon cancer and MDA-MB-231 breast cancer cell lines; and their radical scavenging activity against the 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical species.

槲皮素是一种黄酮类化合物,存在于许多植物材料中,包括通常食用的水果和蔬菜。该化合物以其广泛的生物活性而闻名。在这项研究中,合成了槲皮素的5- O-酰基衍生物,并评估了它们对HCT116结肠癌和MDA-MB-231乳腺癌细胞系的抗增殖活性;及其对2,2'-叠氮基双(3-乙基苯并噻唑啉-6-磺酸)(ABTS)自由基阳离子和2,2-二苯基-1-吡啶并肼基(DPPH)自由基的清除活性。与槲皮素相比,发现四种衍生物具有改善的抗增殖活性,同时保留了自由基清除活性。
