C75, a known inhibitor of fatty acid synthase is postulated to cause significant weight loss through decreased hypothalamic neuropeptide Y (NPY) production. Peripherally, C75, an alpha-methylene-gamma-butyrolactone, reduces adipose tissue and fatty liver, despite high levels of malonyl-CoA. To investigate this
