  The incidence of cancer has been increasing worldwide. Unfortunately, the drugs used in cancer chemotherapy are toxic to both neoplasms and normal tissues, while many available medications have low potencies. Conjugated α,β-unsaturated ketones differ structurally from contemporary anticancer medications, and some of which have

  To design and synthesize highly potent cytotoxins with far greater toxicity to neoplasms than to non-malignant cells.

  A series of N-acyl-3,5-bis(benzylidene)-4-piperidone hydrochlorides 4a-n were prepared and evaluated against Ca9-22, HSC-2, HSC-3, and HSC-4 squamous cell carcinomas as well as aginst HGF, HPLF, and HPC non-malignant cells. QSAR and western blot analyses were performed.

  The majority of compounds display submicromolar CC50 values towards the neoplasms; the figures for some of the compounds are below 10-7 M. In general, 4a-n have much lower CC50 values than those of melphalan, 5-fluorouracil, and methotrexate, while some compounds are equitoxic with doxorubicin. The compounds are far less toxic to the non-malignant cells, giving rise to substantial selectivity index (SI) figures. A QSAR study revealed that both potency and the SI data were controlled to a large extent by the electronic properties of the substituents in the arylidene aryl rings. Two representative compounds 4f and 4g caused apoptosis in HSC-2 cells.

  The compounds in series 4 are potent cytotoxins displaying tumor-selective toxicity. In particular, 4g with an average CC50 value of 0.04 µM towards four malignant cell lines and a selectivity index of 46.3 is clearly a lead molecule that should be further evaluated.

  背景：癌症发病率正在全球范围内增加。不幸的是，用于癌症化疗的药物对肿瘤和正常组织都有毒性，而许多可用药物的效力较低。共轭α，β-不饱和酮在结构上与现代抗癌药物不同，其中一些具有... 目标：设计和合成高效的细胞毒素，对肿瘤细胞的毒性远高于非恶性细胞。 方法：制备了一系列N-酰基-3,5-双(苄亚甲基)-4-哌啶酮盐酸盐4a-n，并对Ca9-22、HSC-2、HSC-3和HSC-4鳞状细胞癌以及HGF、HPLF和HPC非恶性细胞进行了评估。进行了QSAR和Western blot分析。 结果：大多数化合物在肿瘤细胞上显示亚微摩尔水平的CC50值；其中一些化合物的数值低于10-7 M。总体而言，4a-n的CC50值远低于甲氧氨基甲烷、5-氟尿嘧啶和甲氨蝶呤，而一些化合物与多柔比星的毒性相当。这些化合物对非恶性细胞的毒性远低于肿瘤细胞，产生了相当大的选择性指数（SI）值。QSAR研究表明，芳基亚甲基环上取代基的电子性质在很大程度上控制了效力和SI数据。两个代表性化合物4f和4g在HSC-2细胞中引起了凋亡。 结论：系列4中的化合物是具有肿瘤选择性毒性的有效细胞毒素。特别是4g，其对四种恶性细胞系的平均CC50值为0.04 µM，选择性指数为46.3，显然是一个应该进一步评估的领头化合物。

  Cancer remains the second most common cause of death in the US. Due to a recurrent problem with anticancer drug resistance, there is a current need for anticancer drugs with distinct modes of action for combination drug therapy We have tested two novel piperidone compounds, named 2608 (1-dichloroacetyl − 3,5-bis(3,4-difluorobenzylidene)-4-piperidone) and 2610 (1-dichloroacetyl-3,5-bis(3,4-dichlorobenzylidene)-4-piperidone), for their potential cytotoxicity on numerous human cancer cell lines. We found that both compounds were cytotoxic for breast, pancreatic, leukemia, lymphoma, colon, and fibroblast cell lines, with a cytotoxic concentration 50% (CC50) in the low micromolar to nanomolar concentration range. Further assays focused primarily on an acute lymphoblastic lymphoma and colon cancer cell lines since they were the most sensitive and resistant to the experimental piperidones. The cell death mechanism was evaluated through assays commonly used to detect the induction of apoptosis. These assays revealed that both 2608 and 2610 induced reactive oxygen species (ROS) accumulation, mitochondrial depolarization, and activated caspase-3/7. Our findings suggest that the piperidones induced cell death via the intrinsic apoptotic pathway. Additional assays revealed that both piperidones cause cell cycle alteration in lymphoma and colon cell lines. Both piperidones elicited DNA fragmentation, as evidenced by an increment in the sub-G0/G1 subpopulation in both cell lines. Similar to other related compounds, both piperidones were found to act as proteasome inhibitors by increasing the levels of poly-ubiquitinated proteins in both lymphoma and colon cell lines. Hence, the two piperidones exhibited attractive cytotoxic properties and suitable mechanisms of action, which makes them good candidates as anticancer drugs.

  癌症仍是美国第二大常见死因。由于抗癌药物耐药性反复出现，目前需要作用机理不同的抗癌药物进行联合用药。我们测试了两种新型哌啶酮化合物，分别是2608（1-二氯乙酰基-3,5-双（3,4-二氟苄叉）-4-哌啶酮）和2610（1-二氯乙酰基-3,5-双（3,4-二氯苄叉）-4-哌啶酮），测试它们对多种人类癌细胞系的潜在细胞毒性。我们发现这两种化合物对乳腺癌、胰腺癌、白血病、淋巴瘤、结肠癌和成纤维细胞系具有细胞毒性，细胞毒性浓度50%（CC50）在低微摩尔至纳摩尔浓度范围内。进一步的实验主要集中于急性淋巴细胞白血病和结肠癌细胞系，因为它们对实验性哌啶酮最敏感且耐受性最强。通过常用检测细胞凋亡诱导的实验评估细胞死亡机制。这些实验表明，2608和2610均诱导活性氧（ROS）积累、线粒体去极化和激活的半胱天冬酶-3/7。我们的研究结果表明，哌啶酮通过固有凋亡途径诱导细胞死亡。其他实验表明，
