and cancer cell-targeted delivery of photosensitizer (PS) and therapeutic
protein has great potentiality for improving the anticancer effects.
Herein, zeolitic imidazolate framework-8 (ZIF-8) nanoparticles, one
of the most attractive metal–organic framework materials, were
used for coencapsulating the chlorin e6 (Ce6, a potent PS) and cytochrome c (Cyt c, a protein apoptosis inducer);
then the nanoparticle was subsequently decorated with the hyaluronic
acid (HA) shell to form cancer cell-active targeted nanoplatform (Ce6/Cyt c@ZIF-8/HA). The in vitro and in
vivo experiments show the cancer cell targeting capability
and pH-responsive decomposition and the release behavior of Ce6/Cyt c@ZIF-8/HA. Upon light irradiation, the released Ce6 produced
cytotoxic reactive oxygen species for photodynamic therapy. Meanwhile,
the released Cyt c-induced programmed cell death
for protein therapy. Furthermore, the Cyt c worked
normally under hypoxia conditions and could decompose H2O2 to O2 (with peroxidase-/catalase-like activity),
resulting in synergistically improved therapeutic efficiency. These
small molecules and protein codelivery nanoplatforms would promote
the development of complementary and synergetic modes for biomedical
applications.
