Pentixafor is a synthetic, cyclic pentapeptide analog of stromal cell-derived factor-1 (SDF-1 or CXCL12), which is the natural ligand for the C-X-C chemokine receptor type 4 (CXCR4). CXCR4 is a chemokine receptor that plays a critical role in tumor growth, progression, invasiveness, and metastasis. Pentixafor is designed to target CXCR4, which is overexpressed in various cancers and is associated with poor differentiation and aggressive disease.
