  Oligomeric Cholates:  Amphiphilic Foldamers with Nanometer-Sized Hydrophilic Cavities

  摘要：

  The hydroxyl at the C-3 of cholic acid was converted to an amino group, and the resulting aminofunctionalized cholic acid was used as a monomer to prepare amide-linked oligomeric cholates. These cholate oligomers fold into helical structures with nanometer-sized hydrophilic internal cavities in solvent mixtures consisting of mostly nonpolar solvents such as carbon tetrachloride or ethyl acetate/hexane and 2-5% of a polar solvent such as methanol or DMSO. The conformations of the foldamers; were studied by UV, fluorescence, fluorescence quenching, and fluorescence resonance energy transfer. The nature of the polar/nonpolar solvents and their miscibility strongly influenced the folding reaction. Folding was cooperative, as evidenced by the sigmoidal curves in solvent denaturation experiments. The folded conformers became more stable with an increase in the chain length. The folding/unfolding equilibrium was highly sensitive toward the amount of polar solvent. One percent variation in the solvent composition could change the folding free energies by 0.5-1.4 kcal/mol.

  近红外荧光新型胆汁酸衍生物的合成、表征和在肝功能评估中的潜在用途 （NIRBAD）

  摘要：

  传统的血清标志物通常无法准确检测伴随许多肝脏疾病的胆汁淤积。虽然血清胆汁酸 （BA） 水平升高敏感地反映了肝胆功能受损，但改变 BA 池大小和肠肝循环的其他因素也会影响这些水平。为了通过实时监测方法开发用于体外无创肝胆功能评估的荧光探针，使用 1,3-偶极环加成反应将近红外 （NIR） 荧光染料与叠氮化物功能化 BA 衍生物 （BAD） 偶联。对所得化合物 （NIRBADs） 进行色谱（FC 和 PTLC）纯化 （>95%），并使用 ESI 电离与四极杆 TOF 质谱联用，通过荧光法、1H NMR 和 HRMS 进行表征。通过流式细胞术使用稳定表达 BA 载体 NTCP 的 CHO 细胞进行转运研究。通过高分辨率成像分析在麻醉大鼠中检测到体外荧光。通过将炔诺菁 718 与胆酸 （CA） 在酯 （NIRBAD-1） 或酰胺 （NIRBAD-3） 垫片在 COOH 基团，或在 3α 位通过三唑键

  candidates is reported. The disclosed methodology relied on the installation of azide and thiol functionalities at the head and tail positions, respectively, of the BA scaffold and its subsequent decoration by orthogonal click reactions (copper-catalyzed azide–alkyne cycloaddition, thiol–ene or thiol–yne coupling) to introduce BP units and a fluorophore. Because of the troublesome isolation of the target

  据报道，合成了少量新的胆汁酸-双膦酸盐（BA-BP）偶联物作为潜在的候选药物。所披露的方法分别依赖于BA支架的头尾位置上的叠氮化物和硫醇官能团的安装以及随后通过正交点击反应（铜催化的叠氮化物-炔环加成，硫醇-烯或硫醇-炔偶联）的修饰）引入BP单元和荧光团。由于通过标准程序难以分离靶标结合物，因此该方法最终以具有轻质荧光标签的BA支架功能化，从而通过荧光固相萃取快速有效地纯化中间体和最终产物。

The process comprised the solution-phase synthesis of oligopeptides featuring varied chain length and amino acid sequence as well as the preparation of a small library of azidosteroids bearing the azido group either at the side chain or the steroidal nucleus. An alternative strategy relying on a sequential peptide coupling/CuAAC-based macrocyclization procedure was also developed
