function of Aβ1−42. On the basis of the O-acylisopeptidemethod, we herein developed a novel photo-triggered “click peptide” of Aβ1−42, for example, 26-N-Nvoc-26-AIAβ42, in which the photocleavable 6-nitroveratryloxycarbonyl (Nvoc) group was introduced at the α-amino group of Ser26 in 26-O-acyl isoAβ1−42 (26-AIAβ42). From the results, (1) the click peptide did not exhibit the self-assembling nature
In this communication, we report a new type of stimuli-responsive amino acid-derived polymer, whose enzyme-degradability can be controlled by pH-induced quantitative conversion of the polymer backbone structure from polyester to polypeptide.
