Application

  • Substrate specificity profiling of SARS-CoV-2 Mpro protease provides basis for anti-COVID-19 drug design: This study highlights the use of Fmoc-Gln(Trt)-OH in the synthesis of peptide substrates for biochemical assays, contributing to the development of COVID-19 therapeutics (Rut et al., 2020).

General description

High purity Fmoc-protected amino acid for research and process production of peptides, with very low levels of dipeptide, free-amino acids and acetic acid impurities.
Fmoc-Gln(Trt)-OH has good solubility properties in most organic solvents, and its use has been shown to result in significantly purer peptides than other derivatives used for the introduction of Gln [1]. Coupling can be performed by standard procedures. The trityl-protecting group is normally removed by 95% TFA in 1-3 hours, with no alkylation of Trp.
