Special Issue Information

Dear Colleagues,

Natural products and their derivatives have been a cornerstone of pharmaceutical research, serving as a rich source of bioactive compounds with diverse chemical structures and therapeutic properties. These naturally occurring molecules, often derived from plants, microorganisms, and marine organisms, provide unique scaffolds that inspire synthetic modifications to enhance their efficacy, stability, and selectivity. The study of these compounds continues to bridge traditional medicine and modern drug discovery, offering promising solutions to address unmet medical needs.

This Special Issue explores the transformative potential of natural products in drug discovery and development. Emphasizing their synthesis, biological evaluation, and structure–activity relationship (SAR) studies, it aims to uncover the mechanisms underlying their therapeutic effects and optimize their efficacy. Natural products, derived from diverse biological sources, have long been integral to pharmaceutical innovation, offering unique molecular frameworks for novel drug development.

For this Special Issue, we welcome contributions highlighting advanced methodologies for isolating, synthesizing, and modifying natural compounds. It also focuses on evaluating their bioactivities, such as antimicrobial, anticancer, and anti-inflammatory properties, and how structural modifications can enhance these effects. Integrating synthetic chemistry, computational modeling, and modern bioanalytical techniques is especially encouraged to provide a comprehensive understanding of these compounds’ mechanisms of action.

Targeted at researchers and professionals in medicinal chemistry, pharmacology, and biotechnology, this Special Issue seeks to foster collaboration across disciplines. Authors are encouraged to submit original research articles that contribute to advancing the field. Submission guidelines and deadlines are available on the journal's online platform.

The Special Issue will includes also articles from the 3rd International Conference on Chemo and BioInformatics (https://iccbikg.kg.ac.rs/), Kragujevac, Serbia, 25–26 September 2025.

Perezone, a sesquiterpene quinone, was the first natural product isolated in crystalline form on the American continent in 1852. It is commonly found in the roots of herbs from the Acourtia species (formerly Perezia). This molecule, along with its synthetic isomer isoperezone, exhibits antineoplastic effects, among others. In this study, an enzymatic reaction (green chemistry) was employed to oxidize the C12−C13 double bond of perezone and isoperezone. This method proved to be more effective than traditional toxic chemical oxidants. As result, epoxides were obtained, followed by acetonides, diols, and esters. All compounds were successfully synthesized and characterized using standard spectroscopic techniques. In breast cancer cell tests, the isoperezone acetonide showed the highest cytotoxicity, with an IC50 of 8.44 µM. Additionally, a computational study was performed at the DFT (B3LYP) level of theory, indicating that the geometrical and energy differences between 6-R and 6-S stereoisomers are 0.5 kcal/mol, and the spectroscopic and electronic properties aligned with the experimental data. Finally, molecular docking revealed binding energies of −8.14 kcal/mol for 6-R and −8.04 kcal/mol for 6-S, with a hydrogen bond of 2.9 Å involving the His121 residue. A chemoinformatic prediction was also conducted to compare cytotoxicity results. Full article

Lavandin essential oil (LEO) (Lavandula × intermedia) is a high-yielding aromatic product with broad bioactive potential, but its direct application is hindered by its volatility, rapid oxidation, and environmental sensitivity. In this study, the microencapsulation of LEO by spray drying using different wall materials was investigated: Maltodextrin (MD), Gum Arabic (GA), Whey Protein Concentrate (WPC), Inulin (IN), and Modified Starch (Hi-Cap). The resulting formulations exhibited encapsulation efficiencies (EEs) of 55.35–83.29%, oil retention (RE) of 49.07–76.65%, and yields of 41.39–71.47%. The MD/GA blend with Tween 80 performed best, as it offered high EE and RE, low residual moisture, fast reconstitution, and strong protection of the encapsulated oil against thermal and moisture stress. Gas chromatography–mass spectrometry (GC–MS) identified 38 volatile components, with linalyl acetate (30.38%) and linalool (24.65%) being the major components. Biological tests confirmed that the antimicrobial and antifungal activity of lavandin against some pathogens was maintained even when a much lower concentration of the oil (1–5%) was used in encapsulated form. Antioxidant activity decreased after encapsulation, while tyrosinase inhibition increased, indicating cosmetic potential. These results show that spray drying is an effective strategy for stabilizing LEO and expanding its applications in various industries. Full article
