Special Issue Information

Dear Colleagues,

Plant and fungi kingdoms synthesize and store various bioactive compounds which are related to numerous health benefits in humans and animals. Additionally, many products from natural sources show significant anti-inflammatory effects. Since inflammation plays an important role in the development and progression of different illnesses, such as arthritis, asthma, cancer, cardiovascular, neurodegenerative, and autoimmune diseases, natural products possessing anti-inflammatory properties have attracted considerable scientific attention.

This Special Issue aims to present review papers and original articles focusing on current knowledge of bioactive natural products with anti-inflammatory properties. The results of anti-inflammatory activity studies documented in vitro and in vivo are appreciated. As for many natural products, there is a lack of data related to their bioactive compounds, and special emphasis is given to the submission of articles with biomolecular experiments. The identification and quantification of compounds with anti-inflammatory properties, their physicochemical characterization, mechanisms of biological activity, and relationships between structure and bioactivity (molecular docking) are welcome as well. Studies related to the complexes of natural products and carriers (as a system for controlled release) or natural products in the final formulation are also appreciated.

Research areas may include but are not limited to:

  • in vitro and in vivo study of anti-inflammatory activity of natural products
  • identification and quantification of compounds with anti-inflammatory properties and their physicochemical characterization
  • mechanisms of anti-inflammatory activity and structure-effect relationships
  • pharmaceutical formulations based on natural products with anti-inflammatory properties
  • delivery and controlled-release systems for natural products with anti-inflammatory properties
  • pharmaceutical process, engineering, biotechnology, and nanotechnology related to the production of natural anti-inflammatory agents
  • natural anti-inflammatory agent design and targeting
  • pharmacodynamics, pharmacokinetics (absorption, distribution, metabolism, and excretion), and toxicokinetics
  • physiological and biochemical effects of natural anti-inflammatory agents on the body

We look forward to receiving your contributions.

Silibinin has considerable therapeutic potential for the treatment of diabetes through anti-inflammatory, antioxidant, and immunomodulatory properties. However, the therapeutic application of silibinin is quite limited due to its poor bioavailability. In the present study, an attempt was made to improve the antidiabetic efficacy of silibinin by its encapsulation in liposomal vesicles. The liposomes with a high encapsulation efficiency of silibinin (96%) and a zeta potential of −26.2 ± 0.6 mV were developed and studied using nicotinamide/streptozotocin-induced diabetic rats. Administration of silibinin-loaded liposomes to diabetic rats lowered glucose levels, increased insulin levels, and improved pancreatic islet architecture. The anti-inflammatory effect of silibinin-loaded liposomes was demonstrated by a decrease in serum C-reactive protein (CRP) levels and a reduced deposition of collagen fibers in the islets of diabetic rats. Furthermore, silibinin-loaded liposomes were more efficient in lowering glucose, alanine transaminase, triglyceride, and creatinine levels in diabetic rats than pure silibinin. In addition, silibinin-loaded liposomes had a significantly better effect on beta-cell mass and Glut2 glucose receptor distribution in diabetic islets than pure silibinin. The present results clearly show that liposome encapsulation of silibinin enhances its antidiabetic efficacy, which may contribute to the therapeutic benefit of silibinin in the treatment of diabetes and its complications.

The aims of the present research include (1) optimization of extraction from Vaccinium myrtillus leaf waste via investigation of plant material:medium ratio, extraction medium, and extraction period, employing extractions at room and high temperatures, or using ultrasound and microwaves (M, HAE, UAE, and MAE, respectively), (2) physicochemical characterization, and (3) investigation of extract biological potential. The statistical analysis revealed that optimal levels of parameters for the greatest polyphenolic yield were a proportion of 1:30 g/mL, ethyl alcohol 50% (v/v) during 2 min of microwave irradiation. By LC-MS analysis, 29 phenolic components were detected; HAE showed the highest richness of almost all determined polyphenols, while chlorogenic acid and quercetin 3-O-glucuronide were dominant. All extracts showed a high inhibition of Staphylococcus aureus growth. The effect of different parameters on extracts’ antioxidant capacity depended on the used tests. The extracts also showed a stimulative influence on keratinocyte viability and anti-inflammatory activity (proven in cell-based ELISA and erythrocyte stabilization assays). The extraction procedure significantly affected the extraction yield (MAE ≥ maceration ≥ UAE ≥ HAE), whereas conductivity, density, surface tension, and viscosity varied in a narrow range. The presented research provides evidence on the optimal extraction conditions and technique, chemical composition, and antioxidant, antimicrobial, anti-inflammatory, and keratinocyte viability properties of bilberry extracts for potential applications in pharmacy and cosmetics.
