Photo-Assisted NanoPROTACs for Targeted Cancer Therapy.

Area of Science:

• Biochemistry
• Nanotechnology
• Oncology

Background:

• Proteolysis targeting chimeras (PROTACs) degrade proteins via the ubiquitin-proteasome pathway.
• Conventional PROTACs face challenges like poor permeability and off-target effects.
• Photo-assisted nano-proteolysis targeting chimeras (nanoPROTACs) integrate nanotechnology and light-activated control.

Purpose of the Study:

• To provide a comprehensive overview of photo-assisted nanoPROTACs.
• To discuss the design principles and mechanisms of nanoPROTACs.
• To highlight their potential in precision oncology and stimuli-responsive therapeutics.

Main Methods:
