Rink Amide Linker

Uses

Rink amide linker (CAS# 145069-56-3) is a selective aldose reductase inhibitor and a potential antidiabetic drug.

Application

Most linkers are bifunctional spacers, with one end permanently anchoring to the resin and the other end temporarily linking to the peptide. Peptides anchoring to Rink linker can be easily cleaved under acidic conditions. Since the discovery of Rink linker, it has been grafted to a variety of resins and widely used for scientific investigations and industrial solid-phase peptide synthesis. Thus, Rink Amide Linker is the key reagent to prepare this series of Rink-resins[1].

Origin

Rink Amide Linker was first designed by Rink and further developed by Bernatowicz and co-workers for the preparation of peptide C-terminal amides[1]. Rink Amide Linker is also known as commercial Knorr linker.
