Inhibition of fatty acid synthase (FAS) by the irreversible inhibitor cerulenin leads to cytotoxicity and apoptosis in human cancer cell lines.1 C75 is a more stable inhibitor of FAS than cerulenin that leads to profound weight loss and feeding inhibition in both high-fat diet wild type obese and leptin-deficient ob/ob mice.2 C75 is also cytotoxic to many human cancer cell lines, an effect believed to be mediated by the accumulation of malonyl-coenzyme A in cells with an upregulated FAS pathway.3
