Peptide R54
Peptide R54 (Pep R54; CXCR4 antagonist peptide 19) is an antagonistic peptide targeting CXCR4 with significant anticancer activity. Peptide R54 inhibits CXCR4-dependent cell migration, epithelial-mesenchymal transition, and lung metastasis development, with better serum stability and higher CXCR4 affinity than the lead compound (IC50=20 nM). Peptide R54 synergizes with anti-PD-1 therapy to exert anti-tumor activity in vivo, enhances granzyme activity, and reduces infiltration of Foxp3 cells. Peptide R54 can be used in the study of colon cancer, ovarian cancer, and melanoma.
