  • Since its introduction in 2001 by the Nobel laureate chemist Barry Sharpless of the Scripps Research Institute, the copper-catalyzed azide-alkyne reaction has proven extremely valuable for attaching small molecular probes to various biomolecules in a test tube or on fixed cells.

    THE MEDICAL NEWS

  • Click chemistry is best known for a copper-catalyzed azide-alkyne reaction that makes it possible for certain chemical building blocks to "click" together in an irreversible linkage, analagous to the snapping together of Lego blocks.

  • That first peptide - which is about a third of the length of the final capture agent the scientists are trying to make - is then isolated, purified, and modified on one end by the addition of a chemical group called an alkyne.

  • The alkyne group on the added peptide can potentially chemically react with the azide group of the library's peptides, to create a new peptide that is now two segments long.

  • The two-segment-long peptide then is isolated and purified, "and then we modify the end of that with an alkyne and add it back to the library to produce a three-segment peptide, which is long enough to be both selective for and specific to the target protein," Dr. Heath said.
