Description

ATB346 is a hydrogen sulfide-releasing non-steroidal anti-inflammatory drug (NSAID) that inhibits COX and suppresses prostaglandin production. ATB346 exhibits anti-inflammatory, analgesic, antinociceptive, immunomodulatory, and neuroprotective activities. In vivo, this compound attenuates zymosan-induced inflammation, nociception, and immune signaling. ATB346 also prevents ligature-induced periodontal bone loss and pathologies, potentially by suppressing increases in pro-inflammatory cytokine levels. Additionally, ATB346 decreases edema and improves neurological function in animal models of traumatic brain injury (TBI). ATB346 is a hydrogen sulfide releasing derivative of naproxen.
