    Product Description

    EMA401 is an orally bioavailable and selective antagonist of the angiotensin II type 2 receptor (AT2; IC50s = 39.5 and 408,000 nM for rat recombinant AT2 and AT1, respectively).1 It inhibits capsaicin-induced calcium influx in cultured human dorsal root ganglion (hDRG) neurons (IC50 = 10 nM) and reduces neurite density and length in rat DRG neuronal cultures.2 EMA401 has analgesic effects in a rat model of neuropathic pain induced by chronic constriction injury.3

    WARNING This product is not for human or veterinary use.
