Protecting Groups in Peptide Synthesis - PubMedProper protecting group manipulation strategies can maximize the yield of the desired product or allow the construction of complex peptide-based structures. Thus, the compatibility and orthogonality of each protecting group are key to achieve the proper control of molecular structure. Herein, we describe some common protecting groups and their
p-Methoxybenzyl (PMB) Protective Group | Chem-Station -- &#; General Characteristics. – p -Methoxybenzyl (PMB or MPM) group can be protected or deprotected under the same conditions as benzyl group. It can also be deprotected under mildly oxidizing conditions using DDQ (dichlorodicyanobenzoquinone) or strongly acidic conditions. -There are two dimethoxybenzyl (DMB or DMPM) groups (,
Fmoc-Arg(Pmc)-OH, [--] - peptide.comThe Pmc protecting group on Fmoc-Arg(Pmc)-OH has approximately the same lability as tBu based protecting groups and can be removed with TFA at the same time the peptide is cleaved from Wang or Rink amide resin. The Pmc group is a little less acid labile than the similar Pbf group. In general, arginine sidechain protecting groups in order of
Fmoc Resin Cleavage and Deprotection - Sigma-AldrichThe Mtr group is less acid-labile than PMC or Pbf groups, and its complete removal can take as long as hours. In such cases where Trp is present with several Mtr protecting groups, it is extremely useful to be able to optimize the cleavage conditions by monitoring the removal of this protecting group by HPLC.
