摘要:
利用FMOC化学固相多肽合成法合成了3种含精氨酸的小分子硼酸肽(标记为BPs(13))。在生理pH下,含阳离子的硼酸肽可自组装形成有序超分子纳米组装体。二羟基酚染料茜素红与硼酸肽可特异性结合形成五元环硼酸酯,伴随荧光和颜色的显著变化,可进一步调控硼酸肽的自组装行为。通过扫描电镜研究茜素红调控前后硼酸肽的自组装形态,并用红外光谱和圆二色谱研究其自组装机理。结果表明,3种含精氨酸硼酸肽在生理pH下可自组装形成不同的超分子纳米组装体。通过茜素红的调控,茜素红/硼酸肽化合物,可自组装形成更有序,更精致的超分子聚集体。
Abstract:
Three arginine containing oligo borono peptides (BPs(1 3)) were synthesized by employing a standard FMOC chemistry SPPS. BPs(13) could spontaneously selfassemble into supramolecular architectures at a physiological environment. With recognition between BPs and alizarin red S (ARS), the fivemembered ring borate esters (ARS/BPs) could be formed with dramatic changes in fluorescent feature and visible color. These selfassembled supramolecular architectures were observed by scanning electron microscope (SEM) and their selfassembly mechanisms were explored by Fourier Transform Infrared Spectroscopy (FTIR) and Circular Dichroism (CD). It was found that BPs were capable of selfassembling into wellordered supramolecular architectures, and after recognition of ARS, ARS/BPs could further selfassemble into more ordered and sophisticated supramolecular architectures.
