제목 pH-activated helical polypeptide eliciting selective pro-apoptotic activity
초록 Atificial cationic helical polypeptides were endowed with the enhanced cell-penetrating characteristic. However, the cell-penetrability was not converted by cellular environmental changes, resulting in nonspecific binding. Herein, our group suggested that pH-sensitive anion-donating group were introduced in the helical polypeptide to simultaneously attain tumor targeting and pro-apoptotic activity. The mitochondria-disrupting helical polypeptide undergoing pH-dependent conformational transitions selectively bound to cancer cells and then, destabilized the mitochondrial membranes, thereby provoking apoptosis. This work provides a promising peptide therapeutic systems for cancer therapy.
