Application

• Biphasic electrochemical peptide synthesis: This study highlights the application of Fmoc-Pro-OH in electrochemical peptide synthesis, where slight excesses of reagents and electricity were required, possibly due to steric hindrance (S Nagahara, Y Okada, Y Kitano, K Chiba - Chemical Science, 2021).


• Elucidation of the Mechanism of Endo-XaaC-terminal Peptide Impurity Formation in SPPS: Fmoc-Pro-OH′s role was analyzed in a study investigating impurity formation during solid-phase peptide synthesis, highlighting its distinctively low tendency to form impurities (Y Yang, L Hansen, A Baldi - Organic Process Research & Development, 2021).


• Polymer–peptide delivery platforms: This research utilized Fmoc-Pro-OH in the development of polymer-based DNA delivery systems, emphasizing the effect of oligopeptide orientation on delivery efficacy (SS Parelkar, R Letteri, D Chan-Seng - Biomacromolecules, 2014).


• Structure–Activity Relationship Study of N-Hydroxyphtalimide Derivatives: The study explored the use of Fmoc-Pro-OH in the synthesis of N-Hydroxyphtalimide derivatives for detecting amines during peptide synthesis (K Takamatsu, R Suzuki, A Matsunaga - The Journal of Organic Chemistry, 2023).
