Popis: | Quercetin (QUE) has a wide range of health benefits; however, its application is limited due to its low solubility. We synthesized mono-6-deoxy-6-aminoethylamino-β-cyclodextrin (Et-β-CD) to overcome this limitation. The solubility of QUE was increased 35.1-fold compared with QUE, by its complexation with Et-β-CD. Changes in physicochemical properties following successful complexation were investigated using field emission scanning electron microscope, differential scanning calorimetry, and Fourier transform infrared spectroscopy. The complexation behavior of QUE and Et-β-CD in aqueous solution was monitored by 1H nuclear magnetic resonance (NMR), 2D rotating frame nuclear overhauser, and diffusion-ordered spectroscopy. The molecular docking simulation showed that the oblong shaped QUE is suitable for the formation of a stable complex with a characteristic cavity of Et-β-CD. Furthermore, the antioxidant activity and photostability of QUE was also improved after its complexation with Et-β-CD. From these results, we suggest that the characteristic elliptical cavity of Et-β-CD can be utilized for other hardly soluble drug molecules, which can expand the development of drug delivery systems. |
