A synthetic protocol has been developed for the preparation of 162-residue S-monoglycosylated GM2-activator protein (GM2AP) analogues bearing various amino acid substitutions for Thr69. The facile incorporation of the replacements into the protein was achieved by a one-pot/N–to–C-directed sequential ligation strategy using readily accessible middle N-sulfanylethylanilide (SEAlide) peptides consisting of seven amino acid residues. A kinetically-controlled ligation protocol was successfully applied to the assembly of three peptide segments covering the GM2AP. The native chemical ligation (NCL) reactivities of the SEAlide can be tuned by the presence or absence of phosphate salts. Furthermore, the NCL of the alkyl thioester fragment (GM2AP (1–31)) with the N-terminal cysteinyl prolyl thioester (GM2AP (32–67)) proceeded smoothly to yield the 67-residue prolyl thioester, with the prolyl thioester moiety remaining intact. This newly developed strategy enabled the facile synthesis of GM2AP analogues. Thus, we refered this synthetic protocol as “Tailored Synthesis” for the construction of a GM2AP library.
