ML148 is primarily used as a potent and selective inhibitor of the enzyme fatty acid amide hydrolase (FAAH). By inhibiting FAAH, ML148 increases the levels of endogenous cannabinoids such as anandamide in the nervous system, which plays a role in modulating pain, mood, and inflammation. It is widely employed in preclinical research to study the endocannabinoid system, particularly in models of pain, anxiety, and neurodegenerative disorders. Due to its selectivity, ML148 serves as a valuable tool compound for distinguishing FAAH-related effects from those mediated by other enzymes or receptors in cellular and animal studies. Its application supports the development of therapeutic strategies targeting FAAH for conditions like chronic pain and mood disorders.
