Poor penetration of therapeutic drugs into tumors is a major challenge in anticancer therapy, especially in solid tumors, leading to reduced therapeutic efficacy in vivo. In the study, we used a new tumor-penetrating peptide, CRGDK, to conjugate onto the surface of doxorubicin encapsulated nanoscale micelles. The CRGDK peptide triggered specific binding to neuropilin-1, leading to enhanced cellular uptake and cytotoxicity in vitro and highly accumulation and penetration in the tumors in vivo.
