Stable Phosphohistidine Analogues by Click Chemistry

Protein phosphorylation has been a hot spot in both academic and industrial research for possible drug targets. Instability and isomerism of Phosphohistidine however presents great difficulties in such studies.

Now a stable version of PhosphoHistidine has been developed using click chemistry by Muir and coworkers from The Rockefeller UniVersity and Active Motif, Inc.
JACS 2010, 14327. Published on Web 9/29/2010.

See "Active Motif offers click chemistry reagents" Tuesday, October 5, 2010

The preparation uses the two regio-selective click chemistries, Cu1+ and Ru2+ catalyses, for two stable isomers. They succesfully used these stable analogues in SPPS (solid phase peptide synthesis) to synthesize peptides. Also succesful was the development of the first antibody specifically for pHis.

Two small, good-looking molecules out of click chemistry!

Active Motif offers click chemistry reagents

Active Motif offers research kits, assays, and the TimeLogic® biocomputing systems. Now it has extended to click chemistry reagents such as Chromeo™ Dyes for bioorthogonal labeling.

Active Motif was founded in 1999 and is headquartered in Carlsbad, California, and has international offices in Tokyo, Japan and Brussels, Belgium.

A collection of vendors with similar offerings was compiled previously:

M.G. Finn to head ACS Combinatorial Science

September 1, 2010

Laboratory address

M.G. Finn, Ph.D., of Scripps Research Institute, was appointed as Editor-in-Chief of "ACS Combinatorial Science", the former "Journal of Combinatorial Chemistry". The revision calls for its expansion to include biological and materials combinatorial and high throughput studies.

Finn’s research interests include traditional and combinatorial synthesis of biologically active compounds, traditional and combinatorial development of transition metal catalysis, and development of reactions for organic synthesis and materials science. He was part of the team who developed the first click chemistries, including copper-cataluzed triazole click chemistry.
