PRLog - Aug. 29, 2014 - GöTTINGEN, Germany -- Isoprenoids in living organisms range in function from pigments and fragrances to vitamins and precursors of sex hormones. One of the most familiar natural substances, rubber, is a polyisoprene. Other commercially valuable isoprenoids are those used as flavourings, solvents, and raw materials for chemicals.
In the 1980s scientists discovered that proteins in animals often have isoprenoid structures containing 15 or 20 carbon atoms attached to a particular side chain of the protein. The isoprenoid is added after the protein is otherwise complete. The so-called prenylated proteins do not function without the isoprenoid. These modifications occur in proteins that induce cancers, and scientists believe that drugs that block protein prenylation can be a means to prevent the spread of the disease in an individual.
Steroids, a class of compounds of great importance in both plants and animals, are not isoprenoids but are derived directly from them.
The new Clickable Isoprenoids represent exclusive tools for isoprenoid research.
Click chemistry was first introduced by K. Berry Sharpless in 2001. It describes a chemical reaction which builds substances by joining small units together. Click-reactions are fast and purposeful with high yields.
The alkyne-modified isoprenoids were developed by the Distefano group at the University of Minnesota as chemical reporters of protein prenylation. The isoprenoids readily penetrate mammalian cells and are used as substrates by prenyltransferases. The pendant alkyne can be derivatized with an azide-containing tag, such as a fluorophore or biotin, via a Cu(I) catalyzed “Click” reaction allowing the prenylated proteins to be identified and quantified.
MoBiTec offers Propargyl-geraniol (Catalog No.: S-0110) and Propargyl-farnesol (Catalog No.: S-0160) manufactured by Echelon Biosciences, USA, to its customers throughtout Europe.
Echelon Biosciences Incorporated (EBI) was incorporated under the laws of the state of Utah as Echelon Research Laboratories, Inc. on October 3, 1997. Initially, EBI was formed from a project under the Center for Cell Signaling, a State of Utah Center of Excellence, with the aim to further the science of lipid cell signaling and critical metabolic enzymes, which provide new and viable targets for the development of potential drugs and diagnostics for cancer, diabetes, inflammation, infections, and cardiovascular disease.
