Click chemistry is not limited to biological conditions: the concept of a "click" reaction has been used in chemoproteomic, pharmacological, biomimetic and molecular machinery applications. [48] Click Chemistry is a powerful tool to probe for the cellular localization of small molecules.
The bioorthogonality of the reaction has allowed the Cu-free click reaction to be applied within cultured cells, live zebrafish, and mice. The absence of exogenous metal catalysts makes the Cu-free chemical reactions suitable for the in vivo applications of bioorthogonal chemistry or bioorthogonal click chemistry. [2]
Copper-free click chemistry is a bioorthogonal reaction first developed by Carolyn Bertozzi as an activated variant of an azide alkyne Huisgen cycloaddition, based on the work by Karl Barry Sharpless et al. Unlike CuAAC, Cu-free click chemistry has been modified to be bioorthogonal by eliminating a cytotoxic copper catalyst, allowing reaction ...
André K. Isaacs (born December 20, 1981) is a Jamaican professor of chemistry researching organic and synthetic chemistry at the College of the Holy Cross. He is also a queer science communicator mainly using TikTok and Twitter, where he posts dancing and choreography videos to teach chemistry lessons. Many of his videos have gone viral on ...
The identification tag will vary depending on the type of analysis being done: biotin and click chemistry handles are suitable for enrichment of labeled proteins prior to mass spectrometry based identification, while fluorescent dyes are used when using a gel-based imaging method, such as SDS-PAGE, to validate interaction with a target.

The utility of the Cu(I)-catalyzed click reaction has also been demonstrated in the polymerization reaction of a bis-azide and a bis-alkyne with copper(I) and TBTA to a conjugated fluorene based polymer. [8] The degree of polymerization easily exceeds 50. With a stopper molecule such as phenyl azide, well-defined phenyl end-groups are obtained ...
The term "click chemistry" was coined by Sharpless around the year 2000, and was first fully described by Sharpless, Hartmuth Kolb, and M.G. Finn at The Scripps Research Institute in 2001. [ 11 ] [ 2 ] This involves a set of highly selective, exothermic reactions which occur under mild conditions; the most successful example is the azide alkyne ...
In organic chemistry, the thiol-yne reaction (also known as alkyne hydrothiolation) is an organic reaction between a thiol (−SH) and an alkyne (−C≡CH). The reaction product is an alkenyl sulfide (−CH=CH−S−). [1] [2] The reaction was first reported in 1949 with thioacetic acid as reagent [3] [4] and rediscovered in 2009. [5]
