A porphysome-based photodynamic O2 economizer for hypoxic tumor treatment by inhibiting mitochondrial respiration

Chem Commun (Camb). 2021 Apr 27;57(34):4134-4137. doi: 10.1039/d1cc00544h.

Abstract

A porphysome-based photodynamic O2 economizer (P-PAT) is prepared for hypoxic tumor therapy. The self-assembled porphyrin bilayers of P-PAT possess high loading capacity to atovaquone (ATO) (nearly 70%), which could restrain mitochondrial respiration to relieve hypoxia and enhance photodynamic therapy.
