Phytochemicals in antiviral drug development against human respiratory viruses.

This review explores the potential antiviral properties of various plant-based compounds, including polyphenols, phytochemicals, and terpenoids. It emphasizes the diverse functionalities of compounds such as epigallocatechin-3-gallate (EGCG), quercetin, griffithsin (GRFT,) resveratrol, linalool, and carvacrol in the context of respiratory virus infections, including SARS-CoV-2. Emphasizing their effectiveness in modulating immune responses, disrupting viral envelopes, and influencing cellular signaling pathways, the review underlines the imperative for thorough research to establish safety and efficacy.

Metal sequestration by Microcystis extracellular polymers: a promising path to greener water treatment.

The problem of heavy metal pollution in water bodies poses a significant threat to both the environment and human health, as these toxic substances can persist in aquatic ecosystems and accumulate in the food chain. This study investigates the promising potential of using Microcystis aeruginosa extracellular polymeric substances (EPS) as an environmentally friendly, highly efficient solution for capturing copper (Cu) and nickel (Ni) ions in water treatment, emphasizing their exceptional ability to promote green technology in heavy metal sequestration. We quantified saccharides, proteins, and amino acids in M.
