Drug repurposing for cancer therapy.

Area of Science:

• Oncology
• Pharmacology
• Drug Discovery

Background:

• Cancer remains a major global health challenge, with drug therapy efficacy limited by resistance and toxicity.
• Novel cancer therapeutics are critically needed to overcome these limitations.
• Drug repurposing, identifying new uses for existing drugs, is a promising strategy.

Purpose of the Study:

• To provide a comprehensive overview of drug repurposing methods for cancer treatment.
• To describe the antitumor properties of candidate repurposed drugs.
• To examine the integration of drug repurposing with nanotechnology and combination therapy.

Main Methods:

• Review of existing literature on drug repurposing in oncology.
• Analysis of antitumor mechanisms targeting cancer hallmarks and the tumor microenvironment.
• Exploration of nanotechnology and combination therapy approaches.

Main Results:

• Repurposed drugs are cost-effective, safe, and accelerate development.
• Candidate drugs target cancer hallmarks and the tumor microenvironment.
• Integration with nanotechnology and combination therapy enhances efficacy.

Conclusions:

• Drug repurposing presents significant advantages for cancer treatment development.
• Challenges in clinical translation exist, but future prospects are promising.
• Repurposed drugs hold potential for improved patient outcomes in oncology.
