Scientists Utilize Biology's Preferred Chemical

Researchers have introduced a novel technique known as phosphorus fluoride exchange (PFEx), which enhances click chemistry by utilizing phosphorus as a chemical connector for complex molecule construction. This advancement holds promise for discovering effective cancer treatments and developing environmentally friendly materials with desirable traits, such as flame retardancy and antimicrobial properties, as phosphorus bonds can be easily recycled. Professor John Moses of Cold Spring Harbor Laboratory (CSHL) emphasizes the importance of molecular diversity in research, suggesting that a wider array of molecules increases the likelihood of valuable discoveries. Alongside Nobel laureate K. Barry Sharpless, Moses has advanced PFEx, which enables the efficient assembly of chemical building blocks. Leveraging the biological significance of phosphorus, researchers can create multidimensional molecules with varying chemical groups around a phosphorus core, expanding the chemical space for potential applications. Initial investigations in Moses' lab focus on exploiting PFEx for targeted cancer therapeutics, allowing for optimized molecular reactivity that minimizes side effects. PFEx also offers a sustainable alternative to traditional chemicals by creating materials with properties enhancing their usability while facilitating safe recycling. The findings were documented in a study published on June 7, 2023, and were funded by various institutions, including the National Cancer Institute.
