merrifield solid phase peptide synthesis
Solid-phase synthesis. Pioneered by Robert Bruce Merrifield, SPPS caused a paradigm shift within the peptide synthesis community, and allows the rapid assembly of a peptide chain through successive reactions of amino acids on an insoluble porous support.
Characteristics. Solid phase peptide synthesis (SPPS), developed by R. B. Merrifield, was a major breakthrough allowing for the chemical synthesis of peptides and small proteins. SPPS results in high yields of pure products and works more quickly than classical synthesis (liquid-phase peptide synthesis, LPPS).
This procedure, known as the Merrifield Synthesis after its inventor R. Bruce Merrifield, involves attaching the C-terminus of the peptide chain to a polymeric solid, usually having the form of very small beads. Separation and purification is simply accomplished by filtering and washing the beads with appropriate solvents.

The solid‑phase used in this method is a polymer support. You will not be examined on the details of the Merrifield solid‑phase method; however, you should be prepared to write a couple of paragraphs describing this important process. For his work on the synthesis of peptides, Bruce Merrifield was awarded the 1984 Nobel Prize in chemistry.
The synthesis of peptides and small proteins in which the resinous polymer supported amino acid and succeeding peptide repeatedly reacts with N‐protected amino acids followed by deprotection until the desired peptide or protein is assembled is generally referred to as the Merrifield solid phase peptide synthesis (or SPPS) and the polymeric resin is known as the Merrified resin.
The concept of solid-phase peptide synthesis (SPPS) is to retain chemistry that has been proven in solution but to add a covalent attachment step that links the nascent peptide chain to an insoluble polymeric support (resin). Subsequently, the anchored peptide is extended by …

Bruce Merrifield developed, and was awarded the Nobel Prize for, solid phase peptide synthesis. Â By anchoring the C-terminal amino acid of the peptide to be synthesized to an insoluble resin support, he was able to use reagents in large excess to drive reactions to completion, then cleave the peptide from the support in relatively pure form
The peptide alkyl amide Psedoargiopinine I11 was synthesized in the solid phase strategy using an allyl linker. 130 Canne et al. introduced thioester resin linker (44) for the solid phase synthesis of peptide a-thioacids. resin linker was recently developed by Zheng et al.

By far, though, solid-phase peptide synthesis is the most common method of peptide synthesis today. Instead of C-terminal protection with a chemical group, the C-terminus of the first amino acid is coupled to an activated solid support, such as polystyrene or polyacrylamide.
