Conformation-switchable helical polypeptide eliciting selective pro-apoptotic activity for cancer therapy

Conformation-switchable helical polypeptide eliciting selective pro-apoptotic activity for cancer therapy
Artificial cationic helical peptides possess an enhanced cell-penetrating property. However, their cell-penetrability is not converted by cellular environmental changes resulting in nonspecific uptake. In this study, pH-sensitive anion-donating groups were added to a helical polypeptide to simultaneously achieve tumor targeting and pro-apoptotic activity. The mitochondria-destabilizing helical polypeptide undergoing pH-dependent conformational transitions selectively targeted cancer cells consequently disrupting mitochondrial membranes and subsequently inducing apoptosis. This work presents a promising peptide therapeutic system for cancer therapy.
