CAY10603 is primarily used in biochemical and pharmacological research to study the mechanisms of inflammation and immune responses. It functions as a potent inhibitor of soluble epoxide hydrolase (sEH), an enzyme involved in the metabolism of anti-inflammatory epoxyeicosatrienoic acids (EETs). By inhibiting sEH, CAY10603 helps to increase the levels of EETs, which play a role in reducing inflammation, vascular tension, and pain. This makes it a valuable tool for investigating pathways related to cardiovascular diseases, chronic pain, and inflammatory conditions. Additionally, it is utilized in preclinical studies to explore its potential therapeutic applications in treating hypertension, diabetes, and other inflammation-related disorders.
