ML335, an opioid mu/delta heterodimer-specific agonist discovered in 2013, was reported to have analgesic effects without tolerance. However, in our assay system with mu/delta heterodimerized receptor-expressing cells, the compound seemed to have low efficacy and low potency to the mu/delta receptors. Based on the fact, we sought to construct and discover compounds that have more specific activities to the mu/delta receptors than that of ML335. In the course of screening assay with approximately 100 newly constructed compounds, we found 5 compounds out of 100 possessing higher affinity to the mu/delta receptors but lower affinity to each of mu or delta opioid receptors. We are now trying to take patents of these compounds and also have been constructing novel compounds extremely specific to the mu/delta heterodimerized opioid receptors.
