• 6,6′-((Methylazanedyl)bis(methylene))bis(2,4-dimethylphenol) Induces Autophagic Associated Cell Death through mTOR-Mediated Autophagy in Lung Cancer

  Autophagy is the multistep mechanism for the elimination of damaged organelles and misfolded proteins. This mechanism is preceded and may induce other program cell deaths such as apoptosis. This study unraveled the potential pharmacological effect of 24MD in inducing the autophagy of lung cancer cells. Results showed that 24MD was concomitant with autophagy induction, indicating by autophagosome staining and the induction of ATG5, ATG7 and ubiquitinated protein, p62 expression after 12-h treatment. LC3-I was strongly conversed to LC3-II, and p62 was downregulated after 24-h treatment. The apoptosis-inducing activity was found after 48-h treatment as indicated by annexin V-FITC/propidium iodide staining and the activation of caspase-3. From a mechanistic perspective, 24-h treatment of 24MD at 60 μM substantially downregulated p-mTOR. Meanwhile, p-PI3K and p-Akt were also suppressed by 24MD at concentrations of 80 and 100 μM, respectively. We further confirmed m-TOR-mediated autophagic activity by comparing the effect of 24MD with rapamycin, a potent standard mTOR1 inhibitor through Western blot and immunofluorescence assays. Although 24MD could not suppress p-mTOR as much as rapamycin, the combination of rapamycin and 24MD could increase the mTOR suppressive activity and LC3 activation. Changing the substituent groups (R groups) from dimethylphenol to ethylphenol in EMD or changing methylazanedyl to cyclohexylazanedyl in 24CD could only induce apoptosis activity but not autophagic inducing activity. We identified 24MD as a novel compound targeting autophagic cell death by affecting mTOR-mediated autophagy.

  自噬是消除受损细胞器和错误折叠蛋白质的多步骤机制。该机制具有先导性，可诱导细胞凋亡等其他程序的细胞死亡。本研究揭示了 24MD 在诱导肺癌细胞自噬方面的潜在药理作用。结果表明，24MD 可同时诱导自噬，自噬体染色和 ATG5、ATG7 的诱导以及泛素化蛋白 p62 的表达表明了这一点。处理 24 小时后，LC3-I 与 LC3-II 发生了强烈的对话，p62 则出现了下调。附件素 V-FITC/ 碘化丙啶染色和 caspase-3 激活表明，48 小时处理后发现了凋亡诱导活性。从机理角度来看，60 μM 的 24MD 处理 24 小时后会大幅下调 p-mTOR。同时，p-PI3K 和 p-Akt 也分别被浓度为 80 μM 和 100 μM 的 24MD 所抑制。我们通过 Western 印迹和免疫荧光检测，比较了 24MD 与雷帕霉素（一种强效的标准 mTOR1 抑制剂）的作用，进一步证实了 m-TOR 介导的自噬活性。虽然 24MD 对 p-mTOR 的抑制作用不如雷帕霉素，但雷帕霉素和 24MD 的联合使用可增强 mTOR 抑制活性和 LC3 活化。将 EMD 中的取代基（R 基）从二甲基苯酚改为乙基苯酚，或将 24CD 中的甲基氮杂环丁基改为环己基氮杂环丁基，只能诱导细胞凋亡活性，而不能诱导自噬活性。我们发现 24MD 是一种新型化合物，它通过影响 mTOR 介导的自噬作用来靶向自噬细胞死亡。

• Selective crown ether based macrocyclization: a model case study from N,N-bis(2-hydroxyalkylbenzyl)alkylamine

  A model case of selective crown ether based macrocycles, i.e., [1+1] or [2+2] macrocycles, obtained from a simple reaction of N,N-bis(2-hydroxyalkylbenzyl)alkylamine, HBA, and ditosylated compounds is proposed. For HBA with the methyl group at ortho and para positions, and at N atom, 1, the reaction between this derivative and the ditosylated compound with three, four, five, or eight atom chain length gives only a [1+1] macrocycle. For HBA with the methyl group at ortho and para positions, but a cyclohexyl group at N atom, 2, the reaction gives both [1+1] and [2+2] macrocyclic types when reacting with the ditosylated compound. The present work indicates that the structure of HBA induces selective macrocyclization to provide both [1+1] and [2+2] macrocycles. (C) 2009 Elsevier Ltd. All rights reserved.

  Structure and conformation of three tridentate ligands are determined. All these three compounds crystallize in different space groups, the details are as follows: Bis[(3,5-dimethyl, 2-hydroxy)-2'-hydroxy-5'-methoxy]benzylcyclohexylamine (DHBC): monoclinic I2/a (a = 17.691(1) Angstrom, b = 9.707(1) Angstrom, c = 24.235(2) Angstrom, beta = 91.028(1)degrees); bis[(3,5-dimethyl, 2-hydroxy)-2'-hydroxy-5'-bromo]benzylcyclohexylamine (DHBrBC): tetragonal P4(1)2(1)2(a = b = 12.1138(1) Angstrom, c = 28.485(1) Angstrom, and bis[(3,5-dimethyl, 2-hydroxy)-2'-hydroxy-5'-bromo]benzylmethylamine (DHBrBM): triclinic P (1) over bar (a = 5.228(1) Angstrom, b = 12.364(1) Angstrom, c = 13.234(1) Angstrom, alpha = 94.04(1)degrees, beta = 95.72(1); degrees gamma = 95.90(1)degrees). The cyclohexane rings in DHBC and DHBrBC assume chair conformation. Both the phenyl rings are planar in all the molecules and orient at angles of 75.5(1)degrees, 62.2(1)degrees, and 53.9(2)degrees, respectively with each other. The bond angles around N atom show the sp(3) character. Inter- and intramolecular O - H ... N and O - H ... O types of hydrogen bondings stabilize the molecules in the unit cell in addition to van der Waals forces.
