摘要: Paclitaxel (PTX) is the first natural plant-derived chemotherapeutic drug approved
by the Food and Drug Administration. However, the clinical applications of PTX
are limited by some drawbacks, such as poor water solubility, rapid blood clearance, nonspecific
distribution, and adverse side effects. Nanocarriers have made important contributions
to drug delivery and cancer therapy in recent years. However, low drug loading
capacity, nanocarrier excipients-induced toxicity or immunogenicity, and complicated
synthesis technologies pose a challenge for the clinical application of nanocarriers. To address
these issues, the self-delivery nanomedicine (SDNs), in which pure drug molecules
directly self-assemble into nanomedicine, have been developed for drug delivery and enhancing
antitumor efficacy. In this review, we comprehensively summarize the recent advances
in PTX-based SDNs for cancer therapy. First, the self-assembly strategies to develop
pure PTX nanodrugs are discussed. Then, the emerging strategies of co-assembly
PTX and other therapeutic agents for effective combination therapy are presented, composing
of combination chemotherapy, chemo-photothermal therapy, chemo-photodynamic
therapy, chemo-immunotherapy, and chemo-gene therapy. Finally, the limitations and
future outlook of SDNs are discussed. The rational design of these unique nanoplatforms
may make a new direction to develop highly efficient drug delivery systems for cancer
therapy.
