(1) Background: This study evaluated the effects of a plant bioactive (Phyto Ax’Cell, Phytosynthese, Mozac, France) on the inflammatory status and health of dairy cows during calving. (2) Methods: 46 Holstein crossbred cows were randomized into a control group (CON, n = 23) and the Phyto Ax’Cell group (PAC, n = 23). PAC received Phyto Ax’Cell at 25 g/cow/day, from 15 days prepartum to 7 days postpartum. Blood analyses were performed weekly from D-7 to D14 to evaluate the energy metabolism and inflammatory status; rectal temperature was measured daily within 14 days from calving day (D0). (3) Results: PAC showed lower serum haptoglobin at D7 (0.55 vs. 0.79 mg/mL; p < 0.05) and D14 (0.44 vs. 0.66 mg/mL; p < 0.05). CON had a higher number of circulating white blood cells and granulocytes on D7 (p < 0.05). Fewer cows from PAC showed hyperthermia (≥39 °C) during the first 2 weeks postpartum (−7%, p < 0.05). Energy metabolism, which was represented by the NEFA/cholesterol ratio, improved (0.21 vs. 0.36 at D0, p < 0.1; 0.19 and 0.15 vs. 0.36 and 0.32, respectively, at D+7 and D+14, p < 0.05) under the plant bioactive supplementation. (4) Conclusions: The results suggest that the anti-inflammatory plant bioactive compound with Brazilian green propolis administered during calving had a beneficial effect on the energy and inflammatory status of dairy cows.

Cyanobacterial blooms have increased in frequency, distribution, and intensity due to climate change and anthropogenic nutrient input. The release of bioactive compounds accumulated in these blooms can affect the health of humans and the environment. The co-occurrence of bioactive metabolites is well-documented in bloom samples from marine and freshwater ecosystems, with fewer reports from unialgal isolates. Cyanobacteria also are important terrestrial ecosystem components, especially in drylands, but reports on bioactive molecules from terrestrial cyanobacteria are sparse. This study determined bioactive metabolite profiles for 71 genera of cyanobacteria from seven orders isolated from freshwater (12 genera), marine (15 genera), and terrestrial (44 genera) habitats originally. Cultures were harvested for bioactive metabolites when entering the late-exponential phase for all 157 strains, and 33 were sampled at both early and late exponential phases. Bioactive metabolites were analyzed using an ultra high performance/pressure liquid chromatography in-line with a time-of-flight mass spectrometer. Overall, 12 bioactive classes of the 28 identified were ubiquitous in all samples. On average, each freshwater genus produced ∼12 bioactive classes, whereas each marine genus contained > 4 bioactive classes, and each terrestrial genus contained ∼6 bioactive classes. While 10 of 12 freshwater genera produced at least 10 bioactive classes, only a single genus each from marine and terrestrial habitats had the same number of bioactive classed accumulated. Aeruginosin was found in 58 of 71 total genera, carmabin in 51 of 71 genera, and anabaenopeptin in 48 of 71 genera. Chemotaxonomic use of these secondary metabolites may help resolve higher-level genetic classification(s). An additional growth curve experiment showed that bioactive metabolites were produced at both early and late exponential growth phases. The bioactive metabolite accumulation pattern between early and late exponential phases differed by bioactive classes, genera, and habitats. This survey of 55 bioactive classes in cyanobacteria isolated from freshwater, marine, and terrestrial habitats (71 genera) provides as one of the first systematic bioactive metabolite profiles for cyanobacteria, which should be useful in environmental and drinking water management. Further, it offers novel insights about the toxin potential of selected terrestrial cyanobacteria.

Phytocannabinoids occurring in Cannabis Sativa L. are unique secondary metabolites possessing interesting pharmacological activities. In this study, the dynamics of thermally induced (60 and 120 °C) phytocannabinoid reactions in four cannabis varieties were investigated. Using UHPLC-HRMS/MS, 40 phytocannabinoids were involved in target analysis, and an additional 281 compounds with cannabinoid-like structures and 258 non-cannabinoid bioactive compounds were subjected to suspect screening. As expected, the key reaction was the decarboxylation of acidic phytocannabinoids. Nevertheless, the rate constants differed among cannabis varieties, documenting the matrix-dependence of this process. Besides neutral counterparts of acidic species, ́neẃ bioactive compounds such as hydroxyquinones were found in heated samples. In addition, changes in other bioactive compounds with both cannabinoid-like and non-cannabinoid structures were documented during cannabis heating at 120 °C. The data document the complexity of heat-induced processes and provide a further understanding of changes in bioactivities occurring under such conditions.

Deregulation of the mechanistic target of the rapamycin (mTOR) pathway plays an important role in cancer genesis and progression, making it an attractive target for cancer treatment. Disrupting the mTOR pathway contributes to uncontrolled cell growth, increased proliferation, and enhanced cell survival, all of which are hallmarks of cancer. The findings imply that the deregulation of the mTOR pathway in cancer provides a compelling basis for therapeutic treatments. Phytochemicals such as flavonoids and polyphenols have been shown to play a key role in suppressing different kinases implicated in PI3K/AKT/mTOR signaling cascades. A thorough study of the molecular connections between bioactive substances, mTOR signaling, and autophagy activation can lead to the creation of personalized treatments that work better and have fewer side effects. Finding out how important it is to target the mTOR pathway and how to use bioactive chemicals from plants to treat cancer are both important discoveries that could lead to more precise medicine and the development of effective cancer drugs. Finally, targeting mTOR pathways using plant-derived chemicals may be a promising therapy strategy for cancer. This review tries to summarize putative plant bioactive chemicals that act on malignancies via mTOR signaling pathways. Furthermore, the paper discusses the role of the mTOR pathway in cancer, specifically its influence on cell growth, proliferation, and survival.

Chyawanprash (CP) is an Ayurvedic health supplement which is made up of a super-concentrated blend of nutrient-rich herbs and minerals. It is meant to restore drained reserves of life force (ojas) and to preserve strength, stamina, and vitality, while stalling the course of aging. Chyawanprash is formulated by processing around 50 medicinal herbs and their extracts, including the prime ingredient, Amla (Indian gooseberry), which is the world's richest source of vitamin C. Chyawanprash preparation involves preparing a decoction of herbs, followed by dried extract preparation, subsequent mixture with honey, and addition of aromatic herb powders (namely clove, cardamom, and cinnamon) as standard. The finished product has a fruit jam-like consistency, and a sweet, sour, and spicy flavor. Scientific exploration of CP is warranted to understand its therapeutic efficacy. Scattered information exploring the therapeutic potential of CP is available, and there is a need to assemble it. Thus, an effort was made to compile the scattered information from ancient Ayurvedic texts and treatises, along with ethnobotanical, ethnopharmacological, and scientifically validated literature, that highlight the role of CP in therapeutics. Citations relevant to the topic were screened.

Chili peppers have been under the spotlight of bioactivity research as they feature a diverse and rich phytochemical profile with multiple health promoting effects. These beneficial properties are related to the chemical composition of chili peppers and is of utmost importance to identify varieties with the strongest bioprospecting potential. In this study, 19 chili pepper varieties were investigated originating from Capsicum annuum L. (n = 3), Capsicum baccatum L. (n = 3) and Capsicum chinense Jacq. (n = 13) species. Firstly, a suspect screening based on a spectral library was applied and the bioactive profile of all samples was acquired using ultra-high-performance liquid chromatography hybrid quadrupole time-of-flight mass spectrometry (UHPLC-q-TOF-MS). The ethanolic extracts were richer in bioactive compounds and exhibited the highest antioxidant capacity. Then, 6 different enzyme assays were performed targeting enzymes involved in non-communicable diseases, such as cholinesterases involved in Alzheimer's disease or pancreatic lipase in obesity. The strongest inhibitory effect was noticed for 6 Capsicum chinense Jacq. varieties (half maximal inhibitory concentration ranging between 0.56 and 9.2 mg/mL), namely Moruga, Naga chocolate, Bhut jolokia, Carolina reaper, Trinidad scorpion moruga and Naga morich. By using the enzyme inhibitory profile, it was feasible to discriminate these 6 varieties from the rest tested based on a principal component analysis (PCA) model. Moderate and strong correlations were also noticed between the relative content of the identified compounds and the enzyme inhibition. Naringenin, a flavanone, and vanillic acid, a phenolic acid, strongly correlated towards human acetylcholinesterase and alpha glucosidase inhibition, respectively. Overall, the presented results underscore the high potential of Capsicum chinense Jacq. species to be used as sources of bioactive natural compounds for nutraceutical applications.

Human immunity involves both innate and adaptive defence mechanisms, with inflammation playing a central role in responding to cellular injury, pathogenic infections, and allergic stimuli. Reactive oxygen species (ROS) are closely associated with the onset and progression of inflammation. While moderate ROS levels function as crucial signalling molecules, excessive ROS can damage cellular components. This study aimed to evaluate the anti-inflammatory and antioxidant potential of plant-derived bioactive compounds including chlorogenic acid, oleuropein, tomatine, and tyrosol using human monocytic cell models (U-937 and THP-1). Differentiation of U-937 and THP-1 cells was induced prior to treatment with the selected bioactive compounds. Cell morphology and integrity were examined utilizing confocal microscopy. Gene expression stability was evaluated using reference genes β-actin and glyceraldehyde 3-phosphate dehydrogenase (GAPDH). Protein expression levels of key inflammatory markers were determined by Western blot analysis. In addition, molecular docking studies were conducted to assess the binding affinity of the compounds to human target proteins [Interleukin-4 (IL-4), 5-Lipoxygenase (LOX-5), Myeloperoxidase (MPO), and Tumor necrosis factor-alpha ( TNF-α)]. No cytotoxic effects were observed in treated cells, and GAPDH was confirmed as a stable reference gene under all experimental conditions. In U-937 cells, treatment with the bioactive compounds led to increased expression of the anti-inflammatory cytokine IL-4 and decreased expression of MPO. Notably, exposure to chlorogenic acid and tyrosol reduced MPO activity. Oleuropein and tyrosol demonstrated a strong suppressive effect on the expression of LOX-5, an enzyme responsible for leukotriene production. All tested bioactive compounds significantly reduced the phorbol 12-myristate 13-acetate (PMA) induced increase in LOX-5 activity. Molecular docking supported the potential of these compounds to interact with key inflammatory proteins, contributing to reduced oxidative stress. The plant-derived compounds, particularly oleuropein and tyrosol from olives, exhibit promising anti-inflammatory and antioxidant effects by modulating ROS-associated signalling pathways and downregulating inflammatory markers. These findings support the therapeutic potential of agricultural waste-derived bioactive in inflammation management and oxidative stress regulation.
