General description

Reagent for the preparation of pure Fmoc-amino acids that are free from contamination by Fmoc-dipeptides [1,2,3].

Application

  • Sequence-defined positioning of amine and amide residues to control catechol driven wet adhesion: This study uses Fmoc-OSu for selective functionalization of amines, demonstrating its role in synthesizing complex molecules with specific adhesive properties (Fischer et al., 2020).
  • Fmoc-OASUD: A new reagent for the preparation of Fmoc-amino acids free from impurities resulting from Lossen rearrangement: Discusses the development of Fmoc-OASUD as a superior alternative to Fmoc-OSu, reducing impurities in peptide synthesis processes (Rao et al., 2016).

Numerous glutamine analogues have been reported as irreversible inhibitors of the glucosamine-6-phosphate (GlcN-6-P) synthase in pathogenic Candida albicans in the last 3.5 decades. Among the reported inhibitors, the most effective N3-(4-methoxyfumaroyl)-l-2,3-diaminopropanoic acid (FMDP) has been extensively studied in order to
