Description:

WARNING: This product is for research use only, not for human or veterinary use.

Olodanrigan, also known as EMA-401 and PD-126055, is an angiotensin AT2 antagonist potentially for treatment of postherpetic neuralgia (PHN). EMA401 targets angiotensin II type 2 receptors, which may have importance for painful sensitization. EMA401 may alleviate pain and provides relief by blocking the AngII induced potentiation which is thought to be coupled to protein kinase A

More Info
Angiotensin II (AngII) is an octapeptide that regulates blood pressure, controls water fluid balance, and pain perception. It activates two G protein-coupled receptors: angiotensin II type 1 receptors (AT1R) and angiotensin II type 2 receptors (AT2R). AngII co-localized in neurons that express substance P and calcitonin gene-related peptide suggesting its presence in nociceptors (noxious-stimuli sensing neurons). EMA401 may alleviate pain and provides relief by blocking the AngII induced potentiation which is thought to be coupled to protein kinase A.
Biological target:
Olodanrigan is an angiotensin II type 2 receptor (AT2R) antagonist.
In vitro activity:
TBD
In vivo activity:
This study previously demonstrated that losartan, an angiotensin II type 1 (AT1) receptor antagonist prevented these changes, and this study attempted to determine the effects of EMA401, an AT2 receptor antagonist in the current study. EMA401 blocked visceral hypersensitivity and colonic hyperpermeability in these models, and naloxone reversed the effects by EMA401. These results suggest that EMA401 may improve gut function via opioid signaling in IBS. Reference: J Pharmacol Sci. 2021 Jul;146(3):121-124. https://pubmed.ncbi.nlm.nih.gov/34030794/
