Sinomenine hydrochloride is a natural anti-inflammatory morphinan analog. Sinomenine hydrochloride causes degranulation of mast cells in mammalian tissues to release histamine and suppresses production of proinflammatory cytokines. Sinomenine hydrochloride also displays antinociceptive activity, possibly through activation of the μ-opioid receptor. Stimulates short-term renewal of human embryonic stem cells (ESCs) in vitro.
