Abstract
There is an urgent need for nonopioid treatments for chronic and neuropathic pain to provide effective alternatives amid the escalating opioid crisis. This study introduces novel compounds targeting the alpha 9 nicotinic acetylcholine receptor (nAChR) subunit, which is crucial for pain regulation, inflammation, and inner ear functions. Specifically, it identifies novel substituted carbamoyl/amido/heteroaryl dialkylpiperazinium iodides as potent agonists selective for human alpha 9 and alpha 9 alpha 10 over alpha 7 nAChRs, particularly compounds 3f, 3h, and 3j. Compound 3h (GAT2711) demonstrated a 230 nM potency as a full agonist at alpha 9 nAChRs, being 340-fold selective over alpha 7. Compound 3c was 10-fold selective for alpha 9 alpha 10 over alpha 9 nAChR. Compounds 2, 3f, and 3h inhibited ATP-induced interleukin-1 beta release in THP-1 cells. The analgesic activity of 3h was fully retained in alpha 7 knockout mice, suggesting that analgesic effects were potentially mediated through alpha 9* nAChRs. Our findings provide a blueprint for developing alpha 9*-specific therapeutics for pain.
