Special Issue Information

Dear Colleagues,

Throughout history, there has been an interest in the study of plants, fungi and algae to obtain compounds. Simple aqueous extractions from plants, flowers and insects have been used to isolate compounds whose flavor, color and odor have been used for different purposes. The therapeutic use of plants in society constitutes part of the universal culture that humanity has accumulated; however, the selection process for randomly collected plants and the phytochemical examination of plants with the aim of identifying new chemical compounds have allowed us to discover a wide range of organic compounds with interesting properties. In medicinal chemistry, one of the main objectives in the development of a drug is to find a suitable candidate that has the desired pharmacological activity (preferably through a single receptor) and very few or no side effects, which is why alternatives are sought, such as the use of aqueous extracts of plants, fungi and algae for the treatment of frequent medical problems, such as infectious, gastrointestinal, pulmonary, metabolic, and cardiovascular diseases. The metabolism of plants is very important and occurs through enzymatic chemical reactions, which generate primary and secondary metabolites that can be isolated, characterized and chemically modified to enhance their biological activities. This Special Issue aims to understand the secondary metabolites present in plants, fungi and algae, as well as their biological effects. Articles that include pharmacological studies using in vitro and in vivo models and that include partial or total chemistry are welcome.

Black chokeberry (BCK), known as Aronia melanocarpa (Michx.) Elliott, has been employed for various purposes throughout history, being exploited both for its nutritional properties (functional foods, beverages, food preservatives, and natural food colorants) and for its therapeutic benefits (including cardiovascular and metabolic settings). This paper presents the first report on the identification of inorganic elements in three standardized BCK extracts: frozen berries (FrozArs), dried berries (DryArs), and evaporated juice (EvArJ). Additionally, the antiproliferative and pro-apoptotic effects of these extracts on human pulmonary artery endothelial cells (HPAECs) were evaluated. Concentrations ranging from 1 μg/mL to 10 μg/mL were tested. Inorganic element analysis revealed detectable levels of metals, including aluminum (Al), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn). Notably, cadmium was found in very low amounts (0.026 μg/g in the FrozArs), while iron was the most abundant element in the juice (597.665 μg/g). MTT assays demonstrated that all three extracts exhibited antiproliferative activity against HPAECs. Cell cycle analysis revealed a decrease in the G2/M phase for all extracts, along with an appearance of the sub-G0 phase at the highest concentration tested. The DryAr extract also slightly reduced the number of cells in the G0-G1 phase. Annexin V/PI staining indicated a mild increase in the percentage of necrotic cells associated with the DryAr extract. The potential implications of these findings are significant, particularly for those interested in the health effects of dietary supplements. Full article

The mangrove ecosystem is reported to have a large diversity of species that develop in environments with high salinity levels. Plant species from mangroves are used in traditional medicine and are potential sources of chemicals entities with therapeutic applications. The present work aims to assess and document the influence of salinity on the antioxidant activity exerted by extracts of mangrove species through spectroscopic and chemical analysis. The highest salinity is recorded in Río Verde (RV) in Petén Neyac (PN), an LPBR site. The leaves of Laguncularia racemosa (from RV and PN) recorded the highest extraction yield (35.29 ± 0.45%). Phytochemical analysis indicated the presence of several families of secondary metabolites in the leaves of Rhizophora mangle, Avicennia germinans, and L. racemosa collected in PN and RV, and the chromatographic profile confirms the complexity of the extracts, especially in L. racemosa-RV. The highest content of chlorophylls, carotenoids, and simple phenols was recorded in R. mangle (in RV and PN); flavonoids were high in A. germinans (RV), and the highest antioxidant activity was recorded in L. racemosa (RV) using the DPPH model (EC50: 39.74 ± 0.91 μg/mL; Emax: 67.82 ± 1.00%). According to HPLC, gallic acid (GA), and quercetin (Q) are important metabolites in L. racemosa. FTIR spectra can identify several chemical groups and fingerprint regions in complex mixtures, such as methanolic extracts of the species under study. In this context, this is the first report on chemical changes resulting from species collected at sites with different degrees of salinity. GA is the main metabolite affected by salinity and participates in the antioxidant activity exerted by the original extract, which could explain the physiological adaptations of L. racemosa and its traditional uses. L. racemosa (RV) is ideal for a bioguided phytochemical study that would yield valuable knowledge about its medicinal properties, support ecological conservation, and drive innovation across multiple industries. Further analytical studies are needed to corroborate the impact of salinity on the biosynthesis of secondary metabolites. Full article

(1) Background: Carbapenem-resistant Acinetobacter baumannii (CBRAB) and Pseudomonas aeruginosa (CBRPA) are critical and high-priority pathogens that require new therapeutic developments. Medicinal plants are valuable pharmaceutical resources. This study explored the anti-infective properties of Mayan plants, Bignonia potosina, and Thouinia paucidentata. (2) Methods: Plant parts were extracted using n-hexane, and their ability to inhibit bacterial growth and counteract resistance mechanisms and virulence factors in CBRAB and CBRPA was assessed. GC-MS analysis of the composition of the non-polar extracts and chemometric techniques correlated the phytoconstituents with anti-infective properties. (3) Results: Bignonia potosina liana and flower extracts exhibited potent antibacterial activity against A. baumannii strains (MIC 15.7 to 250 µg/mL) and moderate activity against P. aeruginosa strains (MIC 250 to 1000 µg/mL). Thouinia paucidentata leaf extract at 1000 µg/mL reduced imipenem MIC by 2048-fold for CBRAB, and B. potosina flower extract significantly inhibited A. baumannii catalase activity (at 62.5 µg/mL) and reduced P. aeruginosa pyocyanin production (at 1000 µg/mL). Chemometric analysis identified fatty acids, fatty acid amides, terpenes, and higher alkanes as contributors to their anti-infective properties. (4) Conclusions: This study highlights the potential of medicinal plants in the development of novel anti-infective therapies against CBRAB and CBRPA with various targets. Full article

Cyanobacterial pigments have attracted considerable attention in industry due to their bioactive potential and natural origin. In the present study, the growth dynamics and pigment composition, in terms of chlorophyll a, total carotenoids and phycobiliprotein content, of four cyanobacterial strains isolated from thermal springs, namely Oscillatoria subbrevis CZS 2201, Phormidium ambiguum CZS 2205, Nostoc calcicola TSZ 2203, and Synechococcus sp. CZS 2204, were investigated. The analysis revealed that the maximum quantity of chlorophyll a and total carotenoids was observed in Oscillatoria subbrevis CZS 2201 (26.49 and 3.44 µg mL−1), followed by Phormidium ambiguum CZS 2205 (18.64 and 2.32 µg mL−1), whereas a minimum amount was detected in Synechococcus sp. CZS 2204 (12.13 and 1.24 µg mL−1), respectively. In addition, Oscillatoria subbrevis CZS 2201 showed higher quantity of phycobiliproteins, especially C-phycocyanin (45.81 mg g−1), C-phycoerythrin (64.17 mg g−1) and C-allophycocyanin (27.45 mg g−1). Moreover, carotenoid derivatives of Oscillatoria subbrevis CZS 2201 were also identified, among which β-carotene was the dominant form (1.94 µg mL−1), while the accumulation of zeaxanthin and myxoxanthophyll was relatively high (0.53 and 0.41 µg mL−1, respectively) compared with echinenone and cryptoxanthin (0.34 and 0.23 µg mL−1, respectively). The study revealed that Oscillatoria subbrevis CZS 2201 was a potent producer of secondary carotenoids, including myxoxanthophyll. Full article
