Abstract In the search for more effective prophylactic and possibly curative therapeutics against SARS-CoV-2, an historical-ethnobotanical approach was used to select plants described in Receptarium of Burkhard III von Hallwyl (RBH), influential recipe text from 16th century Switzerland. Ten species were identified based on specific historical uses presumably linked with treatment viral infections as well inflammatory conditions. For each plant candidate, aqueous hydroethanolic extracts have been produced. CellTiter-Glo® Luminescent Cell Viability Assay assess antiviral activity SARS-CoV-2 effect cell viability extracts. Of ten tested, four displayed ≥ 50% at 16.7 µg/ml acceptable (> 75%): Sambucus nigra L. (leaves), Viola odorata Geranium robertianum (arial parts) Artemisia vulgaris (aerial parts). The crude partitioned organic fractions further analyzed. ethyl acetate S. nigra, V.

Peptides are at the cutting edge of contemporary research for new potent, selective, and safe therapeutical agents. Their rise has reshaped pharmaceutical landscape, providing solutions to challenges that traditional small molecules often cannot address. A wide variety natural modified peptides have been obtained studied, many others advancing in clinical trials, covering multiple therapeutic areas. As demand peptide-based therapies grows, so does need sustainable environmentally friendly synthesis methods. Traditional peptide synthesis, while effective, involves draining processes, generating significant waste consuming vast resources. The integration green chemistry offers alternatives, prioritizing eco-friendly reduction, energy conservation. This review delves into transformative potential applying principles by discussing relevant examples application such approaches production active ingredients (APIs) with a structure how these efforts critical an effective transition era field.

ABSTRACT In their environment, plants are exposed to a multitude of abiotic and biotic stresses that differ in intensity, duration severity. As sessile organisms, they cannot escape these stresses, but instead have developed strategies overcome them or compensate for the consequences stress exposure.

To minimise metabolic constraints reduce costs defence, prioritise first‐line defence apoplastic space, involving ascorbate, defensins small peptides, as well secondary metabolites, before cellular processes affected. addition, large number symplastic also provide efficient including chemical antioxidants, antioxidative enzymes, other peptides proteins.

Antibiotic resistance is a significant public health issue, causing illnesses that were once easily treatable with antibiotics to develop into dangerous infections, leading substantial disability and even death. To help fight this growing threat, scientists are developing new methods techniques play crucial role in treating infections preventing the inappropriate use of antibiotics. These effective therapeutic include phage therapies, quorum-sensing inhibitors, immunotherapeutics, predatory bacteria, antimicrobial adjuvants, haemofiltration, nanoantibiotics, microbiota transplantation, plant-derived antimicrobials, RNA therapy, vaccine development, probiotics.
