  • ANALGESIC CONJUGATES
    Publication number: 20090233841
    Abstract: The present invention relates generally to analgesic compounds having a mu opioid receptor agonist linked to a delta opioid receptor antagonist, and to methods for producing analgesia using such compounds. As compared to opioids such as morphine, these compounds can cause less tolerance, physical dependence, and/or constipation. These compounds are also more potent than morphine and are able to cross the blood brain barrier, thereby allowing for peripheral (e.g., IV) administration.
