U-47931E(CAT: R066801) is a synthetic opioid analgesic, structurally distinct from traditional opioids like morphine, as it belongs to the benzamide chemical class. It was originally developed in the 1970s by the pharmaceutical company Upjohn as part of a series of compounds aimed at providing potent analgesia with potentially lower addictive potential. U-47931E acts primarily as a potent agonist at the mu-opioid receptors, producing strong analgesic effects similar to those of other opioids, but it also carries significant risks of respiratory depression and overdose. Although it was never marketed for medical use, U-47931E has gained attention in research settings and among recreational drug users, particularly in the context of illicit drug markets. Its pharmacological profile makes it a subject of interest in studies focused on pain management, opioid receptor pharmacology, and the ongoing search for safer analgesic alternatives.
