Abstract:
The efficient synthesis of homogeneous MUC1 peptide oligomers using sequential ligation reactions in the N-to-C and C-to-N directions is reported. The bi-directional ligation strategy makes use of thioester formation via N → S acyl shift chemistry in combination with peptide ligation reactions and was used to prepare a library of peptide oligomers ranging in molecular mass from 3.8-9.4 kDa, comprised of between 2 and 5 repeats of the MUC1 variable number tandem repeat sequence.
