糖脂生物表面活性剂受到各个行业领域的关注。我们报道了含有肉豆蔻酰 (C14)、棕榈酰 (C16) 或硬脂酰 (C18) 末端链长度的对映体纯聚酰胺糖 (PAS) 作为糖脂生物表面活性剂的模拟物的合成和表征。这些两亲聚合物是水溶性的,采用螺旋二级结构,在高于240°C的温度下分解,无细胞毒性,并自组装成纳米结构。包含较短亲水链长度和疏水 C14 链的聚合物在所有聚合物中表现出最低的表面张力。
Glycolipid biosurfactants are of interest for various industry sectors. We report the synthesis and characterization of enantiopure poly-amido-saccharides (PASs) containing myristoyl (C14), palmitoyl (C16), or stearoyl (C18) terminal chain lengths as mimetics of glycolipid biosurfactants. These amphiphilic polymers are water soluble, adopt a helical secondary structure, decompose at temperatures greater than 240 °C, are non-cytotoxic, and self-assemble into nanostructures. Polymers containing the shorter hydrophilic chain lengths and the hydrophobic C14 chain exhibit the lowest surface tension among all polymers.
