GR-89696

GR-89696 is a drug which acts as a highly selective κ-opioid agonist.^[1] It has been studied in various animal species, and has been described as selective for the κ₂ subtype.^[2][3][4] Recent studies have suggested that GR-89696 and related κ₂-selective agonists may be useful for preventing the itching which is a common side effect of conventional opioid analgesic drugs, without the additional side effects of non-selective kappa agonists.^[5] The structure bound to the κ-opioid receptor has been reported.^[6]
