Encapsulation of Babchi Oil in Cyclodextrin-Based Nanosponges: Physicochemical Characterization, Photodegradation, and In Vitro Cytotoxicity Studies. Pharmaceutics 2018; 10:pharmaceutics10040169. [PMID: 30261580 PMCID: PMC6321157 DOI: 10.3390/pharmaceutics10040169] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2018] [Revised: 08/16/2018] [Accepted: 08/20/2018] [Indexed: 12/02/2022] Open
Abstract
Babchi (Psoralea corylifolia) oil is an important essential oil used in several traditional medicines to cure various disorders. This phytotherapeutic agent possesses a number of pharmacological activities including antibacterial, antifungal, antioxidant, anti-inflammatory, immunomodulatory, and antitumor factors. However, volatile nature, poor stability, and solubility of babchi oil (BO) restrict its pharmaceutical applications. Therefore, the aim of the present work was to encapsulate this oil in β-cyclodextrin nanosponges (NS) in order to overcome the above limitations. To fabricate nanosponges, β-cyclodextrin was cross-linked with diphenyl carbonate in different molar ratios viz. 1:2, 1:4, 1:6, 1:8, and 1:10. The blank nanosponges were loaded with BO using the freeze-drying method. The particle size of the BO loaded nanosponges was found to lie between 200 and 500 nm with low polydispersity index. Furthermore, the zeta potential, the Fourier transform infrared spectroscopy, X-ray diffraction, thermal analysis, and electron microscopy were carried out for characterization of BO nanosponges. Results obtained from spectral analysis ascertained the formation of inclusion complexes. Additionally, solubilisation efficiency of BO was checked in distilled water and found enhanced by 4.95 times with optimized β-cyclodextrin nanosponges. The cytotoxicity study was carried out by the MTT assay using HaCaT cell lines. A significant improvement in photo-stability of essential oil was also observed by inclusion innanosponges. Lastly, the optimized formulation was tested for antibacterial activity using Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. Therefore, encapsulation of BO in nanosponges resulted in efficacious carrier system in terms of solubility, photo-stability, and safety of this oil along with handling benefits.

Abstract
In this study a brushite cement was doped with the chain-breaking antioxidant Trolox. The effect of the antioxidant on the physical properties of the cement was evaluated and the release of Trolox was monitored by UV spectroscopy. The ability of the Trolox set free to scavenge reactive oxygen species (ROS) released by macrophages was determined in vitro using a luminol-amplified chemiluminescence assay. Trolox did not modify the crystalline phases of the set cement, which mainly formed crystalline brushite after 7 days in humid conditions. The setting time, compressive strength and morphology of the cement also remained unaltered after the addition of the antioxidant. Trolox was slowly released from the cement following a non-Fickian transport mechanism and nearly 64% of the total amount was released after 3 days. Moreover, the capacity of Trolox to scavenge the ROS released by macrophages increased in a dose-dependent manner. Trolox-loaded cements are expected to reduce some of the first harmful effects of acute inflammation and can thus potentially protect the surrounding tissue during implantation of these as well as other materials used in conjunction.

Abstract
Recent advances in photobleaching and blinking prevention have aided the advancement of single-molecule and super-resolution fluorescence microscopy. However, a common mechanism of the action of antifading agents such as Trolox is still missing. In this communication we present evidence that Trolox acts in accordance with a mechanism that involves triplet quenching through electron transfer and subsequent recovery of the resulting radical ion by the complementary redox reaction. The required oxidant for this unifying mechanism based on a reducing and oxidizing system (ROXS) is formed via (photo-) reaction with molecular oxygen. We present evidence that this oxidized form is a quinone derivative of Trolox with strong oxidizing properties. These findings shed light on many contradicting results regarding the action of antifading agents and might lead to a common mechanistic understanding of photobleaching and its prevention. Finally, a recipe on the proper use of Trolox as an antifading agent is provided.
