A safe and biodegradable γ-cyclodextrin-metal-organic-frameworks (γ-CD-MOFs) was successfully synthesized by using an improved hydrothermal method. In this study, curcumin (Cur) was chosen for testing the encapsulation stability and release performance of γ-CD-MOFs. Results of the crystal structure measurement indicated that the encapsulated curcumin within γ-CD-MOFs via van der Waals forces, hydrophobic interactions and hydrogen bonding was failed to disturb the inherent microtopography and crystallinity of γ-CD-MOFs. Compared to individual γ-CD, the γ-CD-MOFs exhibited improved loading capacity, physicochemical stability as well as controlled-release property in simulated digestion, and hence can be regarded as effective carriers for curcumin. Curcumin-loaded γ-CD-MOFs with a Cur : γ-CD-MOFs mass ratio of 2:3 (Cur-CD-MOFs/3), which showed the highest encapsulation efficiency (67.31 ± 2.25%), improved physicochemical stability and controlled-release performance, was selected for further research and industrialization. Our results demonstrate that γ-CD-MOFs can be regarded as a promising novel carrier for the delivery of curcumin or other hydrophobic nutraceuticals.
一种安全且可生物降解的 γ-环糊精-金属有机骨架(γ-CD-MOFs)通过改进的水热法成功合成。在本研究中,姜黄素(Cur)被选择用于测试 γ-CD-MOFs 的包封稳定性和释放性能。晶体结构测量结果表明,姜黄素通过范德华力、疏水相互作用和氢键被包封在 γ-CD-MOFs 内,这并没有干扰 γ-CD-MOFs 的固有微观形貌和结晶度。与单独的 γ-CD 相比,γ-CD-MOFs 在模拟消化中表现出更高的载药量、物理化学稳定性和控制释放性能,因此可以被视为姜黄素的有效载体。姜黄素负载的 γ-CD-MOFs 中姜黄素与 γ-CD-MOFs 的质量比为 2:3(Cur-CD-MOFs/3),显示出最高的包封效率(67.31±2.25%)、改善的物理化学稳定性和控制释放性能,被选择用于进一步的研究和工业化。我们的结果表明,γ-CD-MOFs 可以被视为一种有前途的新型载体,用于输送姜黄素或其他疏水性营养药物。
