  CLEFMA—An anti-proliferative curcuminoid from structure–activity relationship studies on 3,5-bis(benzylidene)-4-piperidones

  摘要：

  3,5-Bis(benzylidene)-4-piperidones are being advanced as synthetic analogs of curcumin for anti-cancer and anti-inflammatory properties. We performed structure-activity relationship studies, by testing several synthesized 3,5-bis(benzylidene)-4-piperidones for anti-proliferative activity in lung adenocarcinoma H441 cells. Compared to the lead compound 1, or 3,5-bis(2-fluorobenzylidene)-4-piperidone, five compounds were found to be more potent (IC50 <30 mu M), and 16 compounds possessed reduced cell-killing efficacy (IC50 >50 mu M). Based on the observations, we synthesized 4-[3,5-bis(2-chlorobenzyl-idene-4-oxo-piperidine-1-yl)-4-oxo-2-butenoic acid] (29 or CLEFMA) as a novel analog of 1. CLEFMA was evaluated for anti-proliferative activity in H441 cells, and was found to be several folds more potent than compound 1. We did not find apoptotic cell population in flow cytometry, and the absence of apoptosis was confirmed by the lack of caspase cleavage. The electron microscopy of H441cells indicated that CLEFMA and compound 1 induce autophagic cell death that was inhibited by specific autophagy inhibitor 3-methyladenine. The results suggest that the potent and novel curcuminoid, CLEFMA, offers an alternative mode of cell death in apoptosis-resistant cancers. (C) 2010 Elsevier Ltd. All rights reserved.

  3,5-二芳亚甲基-N-苯磺酰基-4-哌啶酮化合物及其制备方法

  摘要：

  本发明涉及十个具有抗肿瘤和抗炎活性的3,5‑二芳亚甲基‑N‑苯磺酰基‑4‑哌啶酮化合物，属于抗肿瘤和抗炎药物技术领域。其制备方法是首先通过4‑哌啶酮盐酸盐分别与芳醛进行克莱森‑施密特缩合反应得到3,5‑二芳亚甲基‑N‑H‑4‑哌啶酮盐酸盐中间体，进而与磺酰化试剂发生苯磺酰化反应得到3,5‑二芳亚甲基‑N‑苯磺酰基‑4‑哌啶酮化合物。该化合物抗肿瘤和抗炎活性好，可避免现在使用的抗肿瘤药的基因毒性，对正常细胞的毒性小，同时具有抗炎活性。制备方法操作简便，反应条件温和，合成产率高，利于其在抗肿瘤和抗炎领域的广泛推广。
