Arylfluorsulfat‐basierte Elektrophile für die kovalente Proteinmarkierung

Abstract: Die selektive kovalente Modifikation eines Zielproteins wird in der chemischen Biologie und Wirkstoffforschung für Aufgaben von der Identifizierung und Charakterisierung von Proteinen und ihren Funktionen bis hin zur Entwicklung zielgerichteter Inhibitoren angewendet. Die meisten kovalenten Liganden weisen ein Affinitätsmotiv und eine elektrophile Gruppe auf, die mit einer nukleophilen Seitenkette des Zielproteins reagiert. Da das Elektrophil unspezifisch mit Nukleophilen reagieren und diese dadurch modifizier… Show more

“…Compared to commonly used protein‐modifying electrophilic warheads, such as acrylamides, [17] vinyl sulfones, [18] and activated esters/amides, [19, 20] SuFEx‐based chemistry that makes use of sulfur(VI) fluorides, including arylfluorosulfates (Ar‐OSO 2 F) and arylsulfonyl fluorides (Ar‐SO 2 F), [21–23] are relatively weak electrophiles and have been used to successfully target lysine in a protein [5, 13, 14, 24] . Ar‐OSO 2 F in particular, is highly stable in aqueous conditions and considered a latent electrophile which becomes activated only under certain circumstances [25] . Taunton et al.…”

“…Click chemistry is a powerful methodology for the synthesis of complex molecules via the molecular assembly of diverse modular building blocks in a highly efficient manner under mild conditions. , Notably, the past decade has witnessed a remarkably growing interest in sulfonyl fluorides, primarily attributed to the advent of sulfur­(VI) fluoride exchange (SuFEx) as the next generation of click chemistry, which is a simple, water- and oxygen-friendly reaction with high yields. The unique reactivity–stability balance exhibited by sulfonyl fluorides, along with their capacity for diverse chemical transformations, has facilitated their widespread applications in organic synthesis, chemical biology, drug discovery, and materials science. Specifically, arylsulfonyl fluorides have garnered considerable attention in the field of life science . Consequently, there is a high demand for studies focusing on the preparation and versatile utilization of sulfonyl fluorides, which have been actively pursued in practice. …”
