Bioactive poly(amino acid)s for multi-modal cancer therapy

Area of Science:

• Oncology
• Nanomedicine
• Materials Science

Background:

• Tumor microenvironments (TMEs) significantly influence cancer progression and treatment efficacy.
• Current therapies often lack specificity for TMEs, necessitating advanced strategies.
• Bioactive materials, particularly poly(amino acid)s, show potential for TME modulation.

Purpose of the Study:

• To review recent advancements in developing bioactive poly(amino acid)s for multi-modal tumor therapy.
• To highlight the synthesis, properties, and TME-modulating capabilities of these materials.
• To explore structure-activity relationships and mechanisms for enhanced cancer treatment.

Main Methods:

• Overview of poly(amino acid) synthesis and their use as nanocarriers.
• Synthesis of biologically responsive, dynamically allosteric, and immunologically effective poly(amino acid)s.
• Investigation of poly(amino acid)s for modulating intracellular, extracellular matrix, and stromal cell microenvironments.

Main Results:

• Poly(amino acid)s demonstrate tunable properties for targeted TME modulation.
• Developed poly(amino acid)s exhibit responsiveness, allosteric regulation, and immune-modulating effects.
• These materials enhance tumor therapy by targeting various aspects of the TME.

Conclusions:

• Bioactive poly(amino acid)s represent a promising platform for innovative cancer therapy.
• Elucidating structure-activity relationships is key to designing effective TME-modulating agents.
