Key result
Treatment with the AT2R antagonist EMA401 resulted in dose-related functional inhibition of capsaicin responses (IC50 = 10 nmol/L) and reduced neurite length and density in sensory neurons.
Effect estimate: IC50 = 10 nmol/L
AT2R antagonists like EMA401 inhibit capsaicin responses and neurite outgrowth in sensory neurons, suggesting potential utility in treating chronic pain and hypersensitivity.

Hypothesis-generating for AT2R antagonists in chronic pain; human studies required before clinical consideration.
Anand et al. (2012) studied Nociception and neuronal regeneration. AT2R antagonist EMA401 and Angiotensin II vs. AT1R antagonist losartan / Control was evaluated on Capsaicin responses, neurite length and density, and cAMP expression (IC50 = 10 nmol/L). Treatment with the AT2R antagonist EMA401 resulted in dose-related functional inhibition of capsaicin responses (IC50 = 10 nmol/L) and reduced neurite length and density in sensory neurons.
