()-trans-C75 is primarily used in research settings to study its effects on fatty acid metabolism and cancer cell growth. It acts as an inhibitor of fatty acid synthase (FAS), an enzyme crucial for the synthesis of fatty acids in cells. By blocking FAS, it disrupts the energy production and lipid synthesis pathways in cancer cells, leading to their inhibition or death. This makes it a valuable tool for investigating potential cancer therapies, particularly in understanding how targeting lipid metabolism can impact tumor growth. Additionally, it is used to explore metabolic disorders and the role of fatty acid synthesis in various diseases. Its application extends to preclinical studies aimed at developing novel treatments for cancers and metabolic conditions.
