EMA401 是具有口服活性、高选择性及外周受限的血管紧张素 Ⅱ 类型 2 受体(AT2R)拮抗剂。它的缓解疼痛的机制可能是：抑制增强的 AngII/AT2R 诱导的 p38 和 p42/p44 MAPK 激活，进而阻碍 DRG 神经元的过度兴奋性及 DRG 神经元的萌发。它可用于研究神经性疼痛。

EMA401, a highly selective AT2R antagonist, inhibition of augmented AngII/AT2R induced p38 and p42/p44 MAPK activation, and hence inhibition of DRG neuron hyperexcitability and sprouting of DRG neurons. EMA401 blocks p38, p42/p44 mitogen-activated protein kinase (MAPK) activation, neurite outgrowth in adult rat DRG neurons, and sensitization of adult rat and human DRG neurons induced by AngII. It inhibits capsaicin responses in cultured hDRG neurons.
