Biochem/physiol Actions

Reparixin is a noncompetitive allosteric inhibitor of the inflammatory CXCL8 (IL-8) chemokine receptors CXCR1 and CXCR2 with IC50 values of 1 nM for CXCR1 and 100 nM for CXCR2. It is believed to prevent receptor signaling by locking CXCR1/R2 in an inactive conformation. Reparixin has been studied to prevent ischaemia-reperfusion injury and inflammation and is clinical trials for triple negative breast cancer and to prevent injury occurring after pancreatic islet transplantation.

Purpose: Chemokine receptor 1 (CXCR1) is recognized as an actionable receptor selectively expressed by breast cancer stem cells (BCSCs). Reparixin is an investigational allosteric inhibitor of chemokine receptors 1 and 2 (CXCR1/2), and demonstrates activity against BCSCs in human breast

Reparixin, a CXCR 1/2 antagonist, has been shown to mitigate ischaemia-reperfusion injury (IRI) in various organ systems in animals, but data in humans are scarce. The aim of this double-blinded, placebo-controlled pilot study was to evaluate the safety and efficacy
