Synonyms: DF 1681Y | repertaxin
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Reparixin is an orally bioavailable compound that has been explored for potential to disrupt IL-8/CXCR1/2 signalling in cancer and transplant indications. It negatively modulates CXCR1 and CXCR2 dependent functions [1], but without inhibiting chemokine binding to either receptor. Direct binding to CXCR1 has only been indicated by molecular modelling, so the mechanism of action of this molecule remains to be fully resolved.

Immunopharmacology Comments
Reparixin blocks a range of activities related to CXCL8 signaling, including leukocyte recruitment (IC50 = 1 nM) and other inflammatory responses, without affecting receptor activation induced by other CXCR1 and CXCR2 agonists.
