Photodynamic and antiangiogenic activities of parietin liposomes in triple negative breast cancer.

Parietin (PTN) is an anthraquinone with promising efficacy in the inhibition of cancer cell proliferation and tumor growth. Due to its hydrophobicity, PTN is sparingly soluble under physiological conditions and has a low bioavailability. Hence, we presented PTN in liposomes to overcome these drawbacks.

Surface tailored zein as a novel delivery system for hypericin: Application in photodynamic therapy.

Zein is an FDA-approved maize protein featured by its manipulative surface and the possibility of fabrication into nanomaterials. Although extensive research has been carried out in zein-based technology, limited work is available for the application of zein in the field of cancer photodynamic therapy (PDT). In this work, we report zein as a carrier for the natural photosensitizer hypericin in the PDT of hepatocellular carcinoma in vitro.
