(−)-trans-C75 is primarily utilized in research focused on understanding metabolic pathways and energy homeostasis. It acts as an inhibitor of fatty acid synthase (FAS), an enzyme crucial for the synthesis of fatty acids in the body. By inhibiting FAS, this compound helps in studying the effects of reduced fatty acid synthesis on cellular processes, including cancer cell proliferation. Researchers use it to explore its potential in suppressing tumor growth, as cancer cells often rely heavily on fatty acid synthesis for their rapid division. Additionally, it is employed in studies related to obesity and metabolic disorders, as it can influence appetite regulation and energy expenditure. Its role in modulating these pathways makes it a valuable tool in biomedical research aimed at developing therapeutic strategies for cancer and metabolic diseases.
