CXCR4 antagonists

Patent Granted A CXCR4 antagonist is a substance which blocks the CXCR4 receptor and prevent its activation. Blocking the receptor stops the receptor's ligand, CXCL12, from binding which prevents downstream effects. CXCR4 antagonists are especially in important for hindering cancer progression because one of the downstream effects initiated by CXCR4 receptor activation is cell movement which helps the spread of cancer, known as metastasis.
