CAY10443 is primarily utilized in research settings as a selective inhibitor of the enzyme soluble epoxide hydrolase (sEH). This enzyme plays a significant role in the metabolism of epoxyeicosatrienoic acids (EETs), which are involved in various physiological processes such as inflammation, vascular tone, and pain regulation. By inhibiting sEH, CAY10443 helps to increase the levels of EETs, thereby promoting their beneficial effects. This makes it a valuable tool in studies focused on understanding and potentially treating conditions like hypertension, inflammation, and neuropathic pain. Additionally, its application extends to exploring its potential therapeutic benefits in cardiovascular diseases and other disorders where sEH activity is implicated.
