NGR peptide Trifluoroacetate is primarily used in biomedical research and therapeutic applications due to its ability to target specific tissues. It is particularly effective in targeting tumor blood vessels, making it valuable in cancer research and treatment. The peptide binds to aminopeptidase N (CD13), a protein often overexpressed in tumor vasculature, enabling targeted drug delivery or imaging agents to reach cancerous tissues more precisely. This property is leveraged in developing cancer therapies, such as drug conjugates or nanoparticles, to enhance treatment efficacy while minimizing side effects. Additionally, it is utilized in diagnostic imaging to identify and monitor tumor growth and angiogenesis. Its applications extend to studying angiogenesis-related diseases and developing novel therapeutic strategies.
