RAP-103 is an orally active, stabilized pentapeptide analog of DAPTA (D-ala-peptide T-amide), and multi-chemokine receptor antagonist.
RAP-103 inhibits chemokine ligands from binding to four specific chemokine receptors: CCR2, CCR5, CCR8, and CXCR4.
RAP-103 exhibits potent antagonism for both CCR2 (IC50 = 4.2 pM) and CCR5 (IC50 = 0.18 pM) in monocyte chemotaxis assays and CCR8 (IC50 = 7.7 fM).
RAP-103 attenuates behavioral hallmarks of neuropathic pain, such as mechanical allodynia and thermal hyperalgesia.
RAP-103 also downregulates corresponding molecular hallmarks of neuropathic pain such as phagocytosis, immune cell migration, and cell membrane ruffling.
RAP-103 inhibits opioid-derived respiratory depression, reduces opioid reinforcement and physical dependence, and normalizes opioid-induced dysregulation of mesolimbic chemokine receptors in rats.
