Abstract
The essential oils of Ligusticum chuanxiong Hort. (CXEO) are considered to be important parts of the pharmacological action of Ligusticum chuanxiong Hort. CXEO have a wide range of applications in various fields. Despite the interesting properties of CXEO, the volatility and low solubility have limited the application. Liposomes are vesicles composed of concentric bilayer lipids arranged around the water environment. Therefore, this study aimed to prepare stable CXEO liposomes (CXEO-LP) to improve the properties. Then, CXEO-LP were prepared by thin film dispersion method and optimized. The results showed that CXEO-LP were well dispersed. Subsequently, in vitro release and antioxidant properties of CXEO-LP were researched. CXEO-LP had slow release effect and oxidation resistance, indicating CXEO-LP may be a potential drug for treating cerebral ischemia-reperfusion injury (CIRI). The nasal mucosa toxicity test and acute toxicity test showed that CXEO-LP had no obvious toxicity to nasal cavity, heart, liver, spleen, lung and kidney tissues. Pharmacodynamic studies found that CXEO-LP significantly improved neurological deficits and brain pathology in a mouse model of CIRI compared to CXEO after intranasal administration. In general, this study showed that CXEO-LP were easy to prepare and continuously released, and had an important development prospect in the treatment of CIRI.

Abstract
Due to its poor stability and rapid metabolism, the biological activity and absorption of epigallocatechin gallate (EGCG) is limited. In this work, EGCG-loaded bovine serum albumin (BSA)/pullulan (PUL) nanoparticles (BPENs) were successfully fabricated via self-assembly. This assembly was driven by hydrogen bonding, which provided the desired EGCG loading efficiency, high stability, and a strong antioxidant capacity. The encapsulation efficiency of the BPENs was above 99.0%. BPENs have high antioxidant activity in vitro, and, in this study, their antioxidant capacity increased with an increase in the EGCG concentration. The in vitro release assays showed that the BPENs were released continuously over 6 h. The Fourier transform infrared spectra (FTIR) analysis indicated the presence of hydrogen bonding, hydrophobic interactions, and electrostatic interactions, which were the driving forces for the formation of the EGCG carrier nanoparticles. Furthermore, the transmission electron microscope (TEM) images demonstrated that the BSA/PUL-based nanoparticles (BPNs) and BPENs both exhibited regular spherical particles. In conclusion, BPENs are good delivery carriers for enhancing the stability and antioxidant activity of EGCG.

Molecules 2022; 27:molecules27196345. [PMID: 36234879 PMCID: PMC9572013 DOI: 10.3390/molecules27196345] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 09/21/2022] [Accepted: 09/22/2022] [Indexed: 11/16/2022] Open
Abstract
Silybin is a complex organic molecule with high bioactivity, extracted from the plant Silybum. As a pharmaceutical substance, silybin’s bioactivity has drawn considerable attention, while its other properties, e.g., thermodynamic properties and thermal stability, have been less studied. Silybin has been reported to exhibit a melting point, and values for its heat of fusion have been provided. In this work, differential scanning calorimetry, thermogravimetry including derivative thermogravimetry, infrared spectroscopy, and microscopy were used to provide evidence that silybin exhibits a thermochemical transition, i.e., softening occurring simultaneously with decomposition. Data from the available literature in combination with critical discussion of the results in a general framework suggest that thermochemical transition is a broad effect exhibited by various forms of matter (small molecules, macromolecules, natural, synthetic, organic, inorganic). The increased formation of hydrogen bonding contributes to this behavior through a dual influence: (a) inhibition of melting and (b) facilitation of decomposition due to weakening of chemical bonds.
