C75 is stable fatty acid synthase (FASN) inhibitor that when administered in racemic form leads to profound weight loss and feeding inhibition in both high-fat diet wild type obese and leptin-deficient ob/ob mice. 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 FASN pathway. (+)-trans-C75 is an enantiomer of C75. Its biologicial activity has not been reported.
