An Intermediate-Centric View of Cascade Cancer Nanotherapeutics

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Oncology

Background:

• Cascade therapies leverage self-amplifying biochemical reactions for cancer treatment.
• Nanotechnology integration (
• cascade nanotherapeutics
• ) enhances anticancer efficacy via coordinated activities.

Purpose of the Study:

• To review recent literature on cascade nanosystems for cancer therapy.
• To propose an intermediate-centric view of antitumor cascades.
• To establish structure-activity relationships from a cascading perspective.

Main Methods:

• Systematic review of recent literature on cascade nanotherapeutics.
• Categorization of nanosystems based on key intermediates (H2O2, O2, 1O2, GSH, hyperthermia, pH, NO).
• Discussion of design principles and mechanistic underpinnings for each category.

Main Results:

• Identified key intermediates driving antitumor cascades: H2O2, O2, singlet oxygen, glutathione, hyperthermia, pH, and NO.
• Established fundamental structure-activity relationships based on cascading mechanisms.
• Highlighted the augmented anticancer efficacy of integrated nanotherapeutics.

Conclusions:

• Cascade nanotherapeutics offer a promising strategy for cancer treatment.
• Future research should focus on simple composition, adaptive intelligence, potent efficacy, and clinical biosafety.
• An intermediate-centric approach provides a fundamental understanding of cascade mechanisms.
