WebJan 1, 2013 · In 1963 Robert Bruce Merrifield introduced the concept and the first implementation of solid-phase peptide synthesis for which he was awarded the 1984 Nobel Prize in chemistry [ 1, 2 ]. Solid-phase peptide synthesis has for decades been the primary … The general process for synthesizing peptides on a resin starts by attaching the first amino acid, the C-terminal residue, to the resin. To prevent the polymerization of the amino acid, the alpha amino group and the reactive side chains are protected with a temporary protecting group. Once the amino acid is attached to … See more The side chains of many amino acids are reactive and may form side products if left unprotected. For successful peptide synthesis, these side … See more In the Boc/Bzl protection scheme, Boc protecting groups are used to temporarily protect the N alpha nitrogen groups of the amino acids and benzyl-based protecting groups provide more … See more In this protection scheme, the alpha nitrogen of the amino acids is protected with the base labile Fmoc group and the side chains are … See more As shown in the mechanism below, tert-butyl carbonium ions are formed during Boc-deprotection. These cations react further with nucleophiles, forming isoprene or tert-butyl adducts. Tryptophan (Trp), cysteine (Cys) or … See more

WebThe solid-phase method was conceived and elaborated by R. B Merrifield ().The concept of SPPS is to retam chemtstry proven m solution and to add a covalent attachment step that links the nascent peptide chain to an msoluble polymeric support.Subsequently, the anchored pepttde is extended by a series of deprotectton and coupling cycles, which are … WebNov 1, 2014 · This continuous-flow system provides a rapid and efficient approach to solid-phase peptide synthesis and was used to examine the influence on product yields of the time and number of couplings per cycle, microporous versus macroporous polystyrene, and tert-butoxy carbonyl (Boc) group versus 9-fluorenylmethoxycarbonyl for amine protection. …
The established method for the production of synthetic peptides in the lab is known as solid phase peptide synthesis (SPPS). Pioneered by Robert Bruce Merrifield, SPPS allows the rapid assembly of a peptide chain through successive reactions of amino acid derivatives on a macroscopically insoluble solvent-swollen beaded resin support.
