Photochemical Bionanoreactor for Efficient Visible-Light-Driven in Vitro Drug Metabolism.

In light of the significance of cytochrome P450 (CYP) catalyzed drug metabolism for drug development and toxicity screening, it is very important to imitate natural metabolic pathways accurately and efficiently in vitro. Herein, a novel and simple photochemical bionanoreactor has been constructed for efficient visible-light-driven in vitro drug metabolism based on eosin-Y-functionalized macroporous ordered silica foams (MOSF-EY). Because of the unique transfer of photoinduced electrons from photosensitizers to CYP heme domain, CYP catalyzed drug metabolism can be in vitro driven by the MOSF-EY nanoreactor under the irradiation of visible light.
