Herein we investigate the incorporation of the Fmoc-Thr-pseudoproline monomer during Fmoc SPPS. Typically, pseudoprolines are incorporated as preformed dipeptides. However, the possibility of using the monomer adds flexibility to the synthesis.read more
As the molecular diversity of cyclic and branched peptides becomes more and more challenging, a high level of orthogonal dimensionality is required. Herein, we present a new category of orthogonal protecting groups.read more
Herein, we report the first-time SPPS of a special peptide sequence via employment of of a serine pseudoproline building block as well as sec-isamyl mercaptan (SIT) as cysteine protecting group.read more
Common protocols for the loading of 2-CTC and MBH-Br resins presume the application of DCM, THF, or DMF; these solvents are considered as undesirable in accordance with modern regulatory rules.read more
With a remarkable amount of peptide therapeutics already on the market and many more to come, there is an ongoing need to improve manufacturing scale and efficiency for a sustainable, global supply.read more
