The adenosine (ADO) A1 receptor (A1R) is a promising therapeutic target for potential non-opioid analgesics to treat neuropathic pain. However, development of analgesic orthosteric A1R agonists has failed because of a lack of sufficient on-target selectivity as well as off-tissue adverse effects. Here, we demonstrate that [2-amino-4-(3,5-bis(trifluoromethyl)phenyl)thiophen-3-yl)(4-chlorophenyl)methanone] (MIPS521), a positive allosteric modulator (PAM) of the A1R, displays in vivo analgesic efficacy through modulation of elevated endogenous ADO that occurs in rat spinal cord in neuropathic pain states. We also report the structure of the A1R co-bound to ADO, MIPS521 and a Gi2 heterotrimer, revealing a novel extrahelical lipid/detergent-facing allosteric binding pocket involving transmembrane helixes 1, 6 & 7. Molecular dynamics simulations and ligand kinetic binding experiments support a molecular mechanism whereby MIPS521 stabilises the ADO-receptor-G protein complex. This study provides proof of concept for structure-based allosteric drug design of disease context-specific, non-opioid analgesics.
