A complete peptide-based drug delivery unit has been designed with a tumor homing domain chemically linked to a syndiotactic cell-penetrating domain. The designed peptides were synthesized, characterized, and tested in vitro for cellular uptake and cytotoxicity evaluation. The differential uptake, cellular internalization, negligible hemotoxicity, selective toxicity to MDA-MB-231 breast cancer cells, and the superior penetration in three-dimensional MDA-MB-231 tumorospheres confirm their utility as a promising delivery vector.
