Novel 3,5-bis(arylidene)-4-piperidone dimers: Potent cytotoxins against colon cancer cells
摘要:
Two novel series of dimeric 3,5-bis(arylidene)-4-piperidones 7 and 8 were prepared as cytotoxic agents. A specific objective of this study was the discovery of novel compounds displaying potent anti-proliferative activities against colon cancers. Most of the compounds demonstrate potent cytotoxicity against HCT116 and HT29 colon cancer cell lines in which the IC50 values range from low micromolar to nanomolar values. In general, the majority of the compounds showed greater cytotoxicity and some degree of selectivity toward HCT116 cells compared to HT29 cells. Compound 9 in which the amidic carbonyl groups were excised was substantially less potent than 8a in both cell lines suggested that the amide groups are important components of the molecules for exhibiting cytotoxicity. Virtually all the compounds were more potent than a reference drug 5-fluorouracil which is used in treating colon cancers as well as a related enone curcumin. QSAR studies were undertaken and some guidelines for amplification of the project have been formulated. Flow cytometry analysis of a representative potent compound 7f revealed that it induces apoptosis in HCT116 cells. (C) 2013 Elsevier Masson SAS. All rights reserved.

treatment of cervical cancer. We describe the synthesis and biological characterization of a new series of 1,3-diphenylpropen-1-one (chalcone) based derivatives lacking the boronic acid moieties of the previously reported chalcone-based proteasome inhibitor 3,5-bis(4-boronic acid benzylidene)-1-methylpiperidin-4-one and bearing a variety of amino acid substitutions on the amino group of the 4-piperidone.
蛋白酶体抑制剂具有治疗宫颈癌的潜力。我们描述了一系列新的基于 1,3-diphenylpropen-1-one(查尔酮)的衍生物的合成和生物学表征,这些衍生物缺乏先前报道的基于查耳酮的蛋白酶体抑制剂 3,5-双(4-硼酸)的硼酸部分benzylidene)-1-methylpiperidin-4-one 并且在 4-piperidone 的氨基上带有多种氨基酸取代。我们的先导化合物2(RA-1) 抑制蛋白酶体活性,并在含有人乳头瘤病毒的宫颈癌细胞中具有改善的剂量依赖性抗增殖和促凋亡特性。此外,当与 FDA 批准的蛋白酶体抑制剂联合测试时,它会诱导协同杀死宫颈癌细胞系。我们的先导化合物使用计算机对接研究探索蛋白酶体抑制的潜在机制表明,其氧代哌啶部分的羰基容易受到蛋白酶体催化位点内 γ-羟基苏氨酸侧链的亲核攻击。

A number of 3,5-diarylidene-4-piperidones (1) and somerelatedquaternaryammonium salts (5) as well as closely relatedanalogs were prepared principally as candidate cytotoxic agents in two screens. The first test system used an average of 54 human tumor cell lines from eight neoplastic diseases, namely leukemia, melanoma, colon, non-small-cell lung, small-cell lung, central nervous system, ovarian
