Enhancing the Inhibition of Corneal Neovascularization Efficacy by Self-Assembled into Supramolecular Hydrogel of Anti-Angiogenic Peptide.

Background: Corneal neovascularization (CNV) is a common eye disease that leads to blindness. New treatment strategies are urgently needed due to the limitations of current treatment methods.

Methods: We report the synthesis of peptide Nap-FFEEPCAIWF ( ) via chemical conjugation of Nap-FFEE ( ) to antiangiogenic peptide PCAIWF . self-assembled into a hydrogel ( ) composed of nanofibers, which enhanced the antiangiogenic function of the epitope.

Results: We developed a novel peptide with an amphiphilic framework, , which could self-assemble into a supramolecular hydrogel with a well-ordered nanofiber structure. The nanofibers exhibited good biocompatibility with corneal epithelial cells, presenting a promising strategy to enhance the efficacy of free peptide-based drugs in the treatment of ocular vascular diseases, such as CNV and other angiogenesis-related diseases.

Conclusion: Nap-FFEEPCAIWF nanofibers provide an alternative approach to enhancing the therapeutic efficiency of free peptide-based drugs against ocular vascular diseases.
