The parent compound from which BU-48 was derived (with N-methyl rather than methylcyclopropyl on the nitrogen and lacking the aliphatic hydroxyl group) is a powerful μ-opioid agonist 1000x more potent than morphine, but in contrast BU-48 has only weak analgesic effects and instead acts primarily as a δ-opioid agonist. Its main effects are to produce convulsions, but it may also have antidepressant effects.
