Alentemol (U-66444B) is a selective dopamine agonist acting at presynaptic receptors to inhibit the release of dopamine. In preclinical studies the compound caused hypothermia in mice and inhibited amphetamine-stimulated omtor activity in mice. U-66444B was investigated by Upjohn Company for the treatment of schizophrenia, but the development of the drug was discontinued.
