Curcuminoids have been reported to possess multiple bioactivities, such as antioxidant, anticancer and anti-inflammatory properties. Three novel series of curcuminoid derivatives (11a-h, 15a-h and 19a-d) with enhanced bioactivity have been synthesized. Among the synthesized compounds, 11b exhibited the most significant activity with an MIC of 0.5 µM /mL against selected medically important Gram-positive cocci (S. aureus and S. viridans) and Gram-negative bacilli (E. coli and E. cloacae). The derivatives exhibited remarkable results in an antioxidant test with an IC50 2.4- to 9.3-folder smaller than curcuminoids. With respect to antiproliferative activity against Hep-G2, LX-2, SMMC7221 and MDA-MB-231, the derivatives exhibited an effect stronger than curcuminoids with an IC50 ranging from 0.18 to 4.25 µM.
姜黄素类化合物已被报道具有多种生物活性,如抗氧化、抗癌和抗炎特性。已经合成了三个具有增强生物活性的新型姜黄素类衍生物系列(11a-h、15a-h和19a-d)。在合成的化合物中,11b表现出最显著的活性,对选定的医学上重要的革兰氏阳性球菌(金黄色葡萄球菌和绿色链球菌)和革兰氏阴性杆菌(大肠杆菌和阴沟肠杆菌)的最低抑菌浓度为0.5 μM/mL。这些衍生物在抗氧化试验中表现出显著结果,其半数抑制浓度(IC50)比姜黄素类化合物小2.4至9.3倍。关于对肝癌细胞Hep-G2、肝星状细胞LX-2、肝癌细胞SMMC7221和乳腺癌细胞MDA-MB-231的抗增殖活性,这些衍生物表现出比姜黄素类化合物更强的作用,IC50范围为0.18至4.25 μM。
