Olodanrigan
Based on 4 publication(s) in Google Scholar
Olodanrigan (EMA401) is a highly selective, orally active, peripherally restricted angiotensin II type 2 receptor (AT2R) antagonist. It is under development as a neuropathic pain therapeutic agent. Olodanrigan (EMA401) analgesic action appears to involve inhibition of augmented AngII/AT2R induced p38 and p42/p44 MAPK activation, and hence inhibition of DRG neuron hyperexcitability and sprouting of DRG neurons.
