Biochem/physiol Actions

Chalcone 4 is a potent, selective inhibitor of the chemokine CXCL12 via direct binding. It is also a small molecule anti-ligand (or neutraligand) of CXCR4 and CXCR7. The chemokine CXCL12 (stromal cell-derived factor-1) and its receptors play pivotal roles in inflammatory responses, normal vascular and neuronal development, as well as in infectious diseases and cancer. Chalcone 4 binds to and activates the chemokine receptors CXCR4 and CXCR7 and stimulates a rapid receptor-mediated intracellular calcium mobilization and signaling through a Pertussis toxin sensitive Gi protein. Chalcone 4 potently and selectively inhibits CXCL12 binding to CXCR4 and CXCR7, and consequent CXCL12-evoked calcium cellular responses. Chalcone 4 binds to the chemokine CXCL12, but not to its receptors.
