Application Arachidonoylserotonin is a fatty acid amide hydrolase (FAAH) inhibitor and transient receptor potential vanilloid-type I (TRPV1) antagonist. Both FAAH and TRPV1 are targets for chronic pain treatment. Arachidonoylserotonin has been used in a study to determine the involvement of endovanilloids in the cortical plastic changes associated with peripheral nerve injury. Biochem/physiol Actions Arachidonoylserotonin is a Fatty Acid Amide Hydrolase (FAAH) Inhibitor and Transient Receptor Potential Vanilloid-Type I (TRPV1) Antagonist. FAAH and TRPV1 are targets for chronic pain treatment. Arachidonylserotonin is a dual target agent and is analgesic in rodents.
