Enamine Co-authors a Discovery of Nonopioid Analgesics Derived from REAL Compounds

We are excited to co-author a new article published in the journal Science: “Structure-based discovery of nonopioid analgesics acting through the α2A-adrenergic receptor”, resulting from a fruitful international collaboration involving:

The article reports on discovering novel nonopioid analgesics from 301M REAL molecules in the ZINC15 library. A large-scale docking of virtual molecules to the α2A-adrenergic receptor binding site, followed by structure determination and studies in the lab, led to the identification of selective agonists that showed nanomolar activity without a sedative effect.
