Ligation of anti-cancer drugs to self-assembling ultrashort peptides by click chemistry for localized therapy

Self-assembling ultrashort peptides from aliphatic amino acids were functionalized with platinum anticancer drugs by click chemistry. Oxaliplatin-derived hybrid peptide hydrogels with up to 40% drug loading were tested for localized breast cancer therapy. Stably injected gels showed significant tumor growth inhibition in mice and a better tolerance compared to the free platinum drug.
