Twenty-eight compounds related to dehydrozingerone (1), isoeugenol (3), and 2-hydroxychalcone (4) were synthesized and evaluated in vitro against human tumor cell replication. Except for isoeugenol analogues 27-35, most compounds exhibited moderate or strong cytotoxic activity against KB, KB-VCR (a multidrug-resistant derivative), and A549 cell lines. In particular, chalcone 15 showed significant cytotoxic activity against the A549 cell line with an IC50 value of 0.6 microg/mL. Furthermore, dehydrozingerone analogue 11 and chalcones 16 and 17 showed significant and similar cytotoxic activity against both KB (IC50 values of 2.0, 1.0, and 2.0 microg/mL, respectively) and KB-VCR (IC50 values of 1.9, 1.0, and 2.0 microg/mL, respectively) cells, suggesting that they are not substrates for the P-glycoprotein drug efflux pump.
合成了28种与脱氢姜酮(1)、异丁香酚(3)和2-羟基查耳酮(4)相关的化合物,并对其进行体外抗人肿瘤细胞复制活性评估。除异丁香酚类似物27 - 35外,大多数化合物对KB、KB - VCR(一种多药耐药衍生物)和A549细胞系表现出中度或强细胞毒性活性。特别是,查耳酮15对A549细胞系表现出显著的细胞毒性活性,IC50值为0.6μg/mL。此外,脱氢姜酮类似物11以及查耳酮16和17对KB(IC50值分别为2.0、1.0和2.0μg/mL)和KB - VCR(IC50值分别为1.9、1.0和2.0μg/mL)细胞均表现出显著且相似的细胞毒性活性,表明它们不是P - 糖蛋白药物外排泵的底物。
