Description

Description générale

Fmoc-ACA-OH is a useful tool for the SPPS of AMC fluorogenic protease substrates by Fmoc SPPS. Fmoc-ACA-OH ^[1] must be first loaded onto a Wang-type resin. Any unreacted linker hydroxyls must be capped using acetic anhydride. Following Fmoc removal, the first amino acid should be coupled with HATU/collidine ^[2]. Insertion of ACA into the middle of a peptide provides fluorogenic substrates for endopeptidases ^[3]. Treatment of the ACC peptide obtained after TFA cleavage with an aqueous base causes facile decarboxylation and formation of the AMC peptide.
