PFAS in most medicines can be replaced with alternatives
Certain medicines contain per- and polyfluorinated alkyl compounds, known as PFAS, which are causing increasing environmental harm because of their long-lasting effects. A study published in Sustainable Chemistry and Pharmacy by the University of Freiburg, commissioned by the German Environment Agency, shows that many PFAS-based active ingredients used in medicines can be replaced by alternative active ingredients. Based on the report's findings, doctors will in the future be able to give preference to prescribing PFAS-free medicines, where this is appropriate from a therapeutic point of view.
How a sugar building block influences viral attachment
Sialic acid is a natural sugar building block found on the surfaces of our cells. It acts as a protective and recognition molecule and plays a central role in the development of the nervous system. Following the modular principle, individual components can be swapped for new building blocks, thereby altering the properties of the sugar. Researchers at Hannover Medical School (MHH) have investigated how these building blocks reach their target. These fundamental findings are also significant because certain influenza and coronavirus strains specifically use modified sialic acids as receptors to enter host cells.
Table sugar could hold a cheaper, quicker key to making vital drugs
Pioneering research has developed a new way of creating carbohydrate-based medicines that could ultimately replace costly drugs for common health conditions, using two cheap basic ingredients—table sugar and vinegar.
Light-activated compound kills antibiotic-resistant bacteria by turning its own defense enzyme against it
Antibiotic resistance is becoming an accelerating crisis because of the overuse and misuse of antibiotics over many years. The problem is exacerbated when antibiotics wipe out susceptible bacteria but leave resistant bacteria behind to multiply, further spreading resistance. There is an ongoing search for new treatments to fight resistant bacteria, and now researchers may have found a way to successfully treat at least one type of resistant bacteria.
