Biological Activity: Flupirtine (D 9998) hydrochloride is an orally active, blood-brain barrier-crossing non-opioid analgesic and neuroprotective agent. Flupirtine hydrochloride is a neuronal potassium channel opener (Kv7 activator), a NMDA receptor antagonist and a GABA receptor activator. Flupirtine hydrochloride stabilizes blood-brain-barrier integrity, reduces oxidative stress and brain leukocyte infiltration, enhances angioneurogenesis, suppresses calcium influx, stabilizes neuronal resting membrane potential, and counteracts focal cerebral ischemia. Flupirtine hydrochloride exhibits analgesic, muscle relaxant properties, protects neurons from excitotoxic, ischemic, or cytokine-mediated death. Flupirtine hydrochloride functions as a non-opioid analgesic without antipyretic or antiphlogistic properties, shows no relevant affinity to opiate receptor. Flupirtine hydrochloride can be used for the research of focal cerebral ischemia, pain, Alzheimer’s disease, or multiple sclerosis[1][2][3][4][5].
