Among the developed PTX nanoformulations, the chimeric polypeptide-conjugated PTX (CP–PTX) and poly-(γ-l-glutamylglutamine)-conjugated PTX (PGG–PTX) nanoparticles were promising and were superior to Abraxane on PK profile and tumor drug exposure, rendering enhanced efficacy in various tumor models11,18. Here, CP is linked to neoplasm.
