Chemical and biology of sulfur fluoride exchange (SuFEx) click chemistry for drug discovery

Compounds containing an S-F bond have garnered intense interest in the chemical and biological literature. In particular, sulfonyl fluorides (RSO2F) are commonly used as covalent protein inhibitors and biological probes. The introduction of the fluorine atom into drugs often leads to significantly promoted medicinal properties, which revolutionized the development of pharmaceuticals and gained attention because of the beneficial properties of these small and highly electro-negative halogens. The sulfonyl fluoride functional group has also been widely adopted throughout the field of chemical biology due to its unique balance between reactivity and stability under physiological conditions. This comprehensive review highlights the recent developments of sul-fonyl fluorides based compounds in a massive range of therapeutic applications. We believe this review article will be helpful to inspire new ideas for structural design and developments of less toxic and potent Sulfur based drugs against the numerous death-causing diseases.
