WebDec 2, 2024 · Bioorthogonal reactions happen in living cells without interfering with the normal biochemical functions of the organism. 43–45 The first bioorthogonal reaction is a Staudinger ligation that occurs between N 3 and a triarylphosphine group. 45 However, due to its poor reactivity, this reaction has not been widely exploited in biological ... WebStaudinger Ligation. Azides react readily with triarylphosphines to form the corresponding iminophophoranes (aza-ylides) with loss of nitrogen. This transformation, originally reported by Staudinger and Meyer, 1 takes place under mild conditions and leads to excellent yields of the aza-ylide products. The initially formed iminophosphorane ...
WebOct 5, 2024 · The reaction, now known as Staudinger ligation or Staudinger-Bertozzi ligation, allowed her to attach fluorescent tags to specially modified sugar molecules after the sugar molecules had already been incorporated into a cell – all without reactions that would muck up a cell’s biochemistry. Webthe Staudinger ligation with phosphines as a means to introduce fluorescence imaging probes.5 Since then, other chemistries have been explored, including Cu-catalyzed cycloaddition of metaboli-cally incorporated alkynyl sugars with azide-functionalized fluo-rophores (i.e., click chemistry)6 and strain-promoted cycloaddition
WebJun 9, 2004 · Bioconjugation made easy: The Staudinger ligation between azides and acyl-modified phosphanes is probably the mildest and most chemoselective ligation reaction. It has found widespread application in chemical biology and can even be used in the complex environment of a living cell (see scheme). WebChemoselective ligation refers to the use of mutually specific reactive chemical groups to accomplish molecular conjugation. Staudinger chemistry, based on the specific crosslinking reaction between azide- and phosphine-labeled molecules, is one of the more promising and versatile examples of chemoselective strategies for applications such as metabolic …
