Formation and Control of Carboxyl- and Hydroxyl-Related Impurities in Peptide Synthesis — Using Asp/Glu and Ser/Thr Residue Side Reactions as Examples
In peptide synthesis, impurities do not always originate from “incomplete coupling” or “incomplete deprotection.” Many quality issues arise because certain functional groups enter undesired reaction pathways under specific conditions. Carboxyl and hydroxyl groups are two typical examples. ...
Peptide Intermediates Difficult to Dissolve and Separate? Route Design and Workup Strategies for Tag-Assisted Liquid-Phase Peptide Synthesis (TAG-LPPS)
The challenges in peptide synthesis often lie not only in whether peptide bonds can be formed, but also in whether the intermediates after each reaction step can dissolve, be separated, and continue to undergo subsequent transformations. For some peptides with high hydrophobicity, long ...
How to Troubleshoot Abnormal Impurities in Peptide Synthesis? Locating Process Issues Through Amino-Related Side Reactions
Abnormal impurities in peptide synthesis are usually not caused by a single factor. Instead, they often result from the combined effects of sequence characteristics, protecting-group strategy, reagent condition, washing efficiency, and post-treatment conditions. In solid-phase peptide synthesis ...
Decision Logic for Peptide Synthesis Routes: Applicability and Criteria for Choosing among SPPS, LPPS, and Recombinant Expression
The core issue in peptide synthesis is no longer simply “what methods are available to link amino acids together,” but rather how to choose a more suitable preparation route for peptides of different lengths, sequence characteristics, modification requirements, and scale-up goals, while ...
Ynamide Coupling Reagents: From Low-Epimerization Activation Pathways to More Practically Usable N→C Inverse Peptide Synthesis
In peptide synthesis, what is often truly difficult to control is not whether an amide bond can be formed, but rather how to minimize epimerization at the α-stereogenic center of the activated carboxylic acid component during activation and the subsequent bond-forming process. This issue is ...
Low-Racemization Control in Peptide Synthesis: An Inverse N→C Peptide Synthesis Strategy via Activated α-Aminoesters
What is commonly described as “low racemization” in peptide synthesis is, in essence, the effort to minimize loss of configuration at the amino acid stereocenter during bond formation, especially at the α-position of the activated carboxylic acid component. Recent reviews have repeatedly pointed ...
Low Racemization in Peptide Synthesis Is Not Just About Reagent Choice: Stereochemical Risk During the Activation Stage and Practical Strategies for Experimental Control
“Racemization” in peptide synthesis is often discussed as if it were mainly a question of whether one coupling reagent is better than another. From the standpoint of reaction chemistry, however, what deserves greater caution is the period after the carboxylic acid has been activated. In many ...

From “High Yield” to “Configuration Retention”: Activation-Stage Risks, Route Differences, and Selection Principles for Coupling Systems
In amide and peptide synthesis, whether a bond can be formed is certainly important. However, for amino acids, peptide fragments, and chiral carboxylic acid substrates containing an α-stereogenic center, another issue often plays an equally decisive role in determining the quality of the ...
From Analytical Instrument to Synthetic Platform: A New Strategy for Reconstructing Automated Flow Solid-Phase Peptide Synthesis with Standard Analytical HPLC

Silicon Reagent-Assisted Peptide Synthesis: Research Progress and Methodological Value of Peptide Bond Formation from Unprotected Substrates
