ABSTRACT
Nanoencapsulation has gained considerable attention because of its unique features and advantages in anticancer drug delivery. Amygdalin (AMY) is an anticancer compound, showing limitations in its applications by low stability. Herein, the inclusion complexes (ICs) of AMY with ß-cyclodextrin (ßCD), and its derivatives such as 2-hydroxypropyl-ßCD (HPßCD) and methyl-ßCD (MßCD) were fabricated. The fabricated AMY/CD-ICs were thoroughly evaluated using Fourier-transform infrared spectroscopy, powder X-ray diffraction, thermogravimetric/differential thermal analysis, proton nuclear magnetic resonance, ultraviolet-visible diffuse reflectance spectroscopy, and photoluminescence techniques. Double reciprocal profile study of the absorption and fluorescence spectra revealed that the AMY formed the ICs with ßCD derivatives at a guest/host stoichiometric ratio of 1/1. The thermal stability of AMY was enhanced as the IC formation aid observed by the shift of thermal degradation temperature of AMY from the range of â¼ 220-250 °C to > 295 °C. Theoretical analyses of the energetic, electronic, and global reactivity parameters of the AMY/CD-ICs were evaluated using the PM3 method. Further assessment of the dissolution diagrams of AMY/CD-ICs revealed a burst release profile. In addition, cell toxicity was evaluated using the MTT assay, and the results showed that AMY/CD-ICs had significantly more efficacious in inhibiting HeLa cancer cells than AMY. These results proved that the IC formations with CDs significantly enhanced the anticancer activity of AMY.
