Novel 3,5-bis(benzylidene)-1-[3-(2-hydroxyethylthio)propanoyl]piperidin-4-ones (3a-e) display potent cytotoxicity and a preferential lethality toward various neoplasms compared to some normal cells. The corresponding sulfonic acid analogues 5a−e and an isostere 4 demonstrated substantially lower activity. The leads 3d and 3e possess very high activity against colon cancer and leukemia cell lines, caused
与一些正常细胞相比,新型 3,5-双(亚苄基)-1-[3-(2-羟乙硫基)丙酰基]哌啶-4-酮 ( 3a-e)显示出有效的细胞毒性和对各种肿瘤的优先致死率。相应的磺酸类似物5a - e和等排体4表现出显着较低的活性。3d和3e导联对结肠癌和白血病细胞系具有非常高的活性,导致 DNA 断裂,并激活 HL-60 细胞中的 caspase-3。在小鼠的短期毒性筛选中,烯酮3b - e具有良好的耐受性。
