Synthesis of amyloid beta peptide 1-42 (E22Delta) click peptide: pH-triggered in situ production of its native form.

Abstract excerpt

Amyloid beta peptide (Abeta) 1-42 is known to be involved in the onset of Alzheimer's disease (AD). We developed a click peptide of Abeta1-42 as a useful tool for AD research on the basis of an O-acyl isopeptide method. The click peptide quickly produced intact Abeta1-42 via a pH-dependent O-to-N intramolecular acyl migration (pH-click). Herein, a click peptide (26-O-acyl isoAbeta1-42 (E22Delta)) of a new mutant...
