Drug classκ-Opioid receptor agonist

GM-3009 is a κ-opioid receptor (KOR) agonist and noribogaine analogue which is under development for the treatment of opioid-related disorders. Its route of administration is unspecified. The drug is a highly potent agonist of the human KOR, with an affinity (Ki) of 0.9 nM or 87.3 nM depending on the radioligand and an EC50Tooltip half-maximal effective concentration of 0.8 nM. In contrast to noribogaine, it did not show pro-arrhythmic effects in fresh human ventricular cardiomyocytes ex vivo. GM-3009 produces antinociceptive effects and dose-dependently reduces oxycodone self-administration in rodents. It is being developed by Gilgamesh Pharmaceuticals. As of June 2024, it is in the preclinical research stage of development. The exact chemical structure of GM-3009 does not yet appear to have been disclosed.
