  胆汁酸-他莫昔芬偶联物在乳腺癌治疗中的设计，合成及机理研究

  摘要：

  我们已经合成了两个系列的胆汁酸他莫昔芬共轭物，使用了三种胆汁酸石胆酸（LCA），脱氧胆酸（DCA）和胆酸（CA）。这些胆汁酸-他莫昔芬共轭物具有1、2和3个他莫昔芬分子，这些分子与胆汁酸的羟基相连，在胆汁酸的尾部具有游离酸和胺官能团。在体外这些胆汁酸他莫昔芬结合物的抗癌活性表明，游离胺首基的基于胆酸-他莫昔芬结合物（CA-担3 -Am与母体药物他莫昔芬和其他基于酸和胺头基的胆汁酸-他莫昔芬结合物相比，）是最有效的抗癌结合物。带有三个他莫昔芬分子的胆酸-他莫昔芬共轭物（CA-Tam 3 -Am）在雌激素受体+ ve和雌激素受体-ve乳腺癌细胞系中均显示出增强的抗癌活性。CA-Tam 3 -Am的增强的抗癌活性是由于更有利的不可逆的静电相互作用，随后这些共轭物插入到膜脂质的疏水核中，导致膜流动性增加。基于膜联蛋白-FITC的FACS分析表明细胞发生凋亡，而细胞周期分析表明细胞停滞在sub G

• Deciphering the role of charge, hydration, and hydrophobicity for cytotoxic activities and membrane interactions of bile acid based facial amphiphiles

  We synthesized four cationic bile add based facial amphiphiles featuring trimethyl ammonium head groups. We evaluated the role of these amphiphiles for cytotoxic activities against colon cancer cells and their membrane interactions by varying charge, hydration and hydrophobicity. The singly charged cationic Lithocholic add based amphiphile (LCA-TMA(1)) is most cytotoxic, whereas the triply charged cationic Cholic add based amphiphile (CA-TMA(3)) is least cytotoxic. Light microscopy and Annexin-FITC assay revealed that these facial amphiphiles caused late apoptosis. In addition, we studied the interactions of these amphiphiles with model membrane systems by Prodan-based hydration, DPH-based anisotropy, and differential scanning calorimetry. LCA-TMA(1) is most hydrophobic with a hard charge causing efficient dehydration and maximum perturbations of membranes thereby facilitating translocation and high cytotoxicity against colon cancer cells. In contrast, the highly hydrated and multiple charged CA-TMA(3) caused least membrane perturbations leading to low translocation and less cytotoxicity. As expected, Chenodeoxycholic add and Deoxycholic add based amphiphiles (CDCA-TMA(2), DCA-TMA(2)) featuring two charged head groups showed intermediate behavior. Thus, we deciphered that charge, hydration, and hydrophobicity of these amphiphiles govern membrane interactions, translocation, and resulting cytoxicity against colon cancer cells.

  1,3-Dipolar cycloaddition of propargyl esters of bile acids to azide group attached at different positions of bile acids gave dimers, trimer, and tetramer linked with 1,2,3-triazole. These dimeric and oligomeric structures were able to solubilize hydrophilic dye-cresol red, in nonpolar solvent. (c) 2007 Elsevier Ltd. All rights reserved.
