Scientists Harness Biology’s Favorite Chemical — Diversity is an essential |
Scientists have developed a new technique called phosphorus fluoride exchange , expanding the realm of click chemistry by using phosphorous as a chemical connector to construct complex molecules.
Together with K. Barry Sharpless, a two-time Nobel laureate, Moses’ lab has developed a chemical transformation called phosphorus fluoride exchange, or PFEx. PFEx efficiently snaps together chemical building blocks to form new molecules, in a reliable process known as click chemistry. Click chemistry already offers chemists a powerful set of tools. As the newest addition to that tool kit, PFEx takes a cue from biology and uses phosphorous as a chemical connector.
Moses says: “Nature has recognized its importance—it’s a privileged group. If we’re trying to make drugs that interact with biology, we should not ignore that fact.” The power and potential of PFEx-based chemistry lie in its ability to rapidly and reliably click together complex molecules using sustainable lab science. The illustration above shows how PFEx is compatible with other click chemistry bonds, including the 2022 Nobel prize-winning CuAAC reactions. Credit: Moses lab/Cold Spring Harbor Laboratory
