BU08073 a Buprenorphine Analog with Partial Agonist Activity at mu Receptors in vitro but Long-Lasting Opioid Antagonist Activity in vivo in Mice

Background & Purpose

Buprenorphine is a potent analgesic with high affinity at μ, δ and κ and moderate affinity at nociceptin opioid (NOP) receptors. Nevertheless, NOP receptor activation modulates the in vivo activity of buprenorphine. Structure activity studies were conducted to design buprenorphine analogues with high affinity at each of these receptors and to characterize them in in vitro and in vivo assays.
