C 75 is an inhibitor of fatty acid synthase .
Fatty acid synthase (FAS) is a multi-enzyme protein that catalyzes fatty acid synthesis. Its main function is to catalyze the synthesis of palmitate from acetyl-CoA and malonyl-CoA. FAS is a target for anticancer drug .
In human breast cancer cells, C 75 reacted preferentially with FAS and inhibited FAS. The antitumor activity of C 75 is likely mediated by its inhibition of FAS . In primary cortical neurons, C 75 inhibited FAS activity and increased the activity of carnitine palmitoyltransferase-
1 (CPT-1) and fatty acid oxidation, which suggested that C 75 might influence cellular energy balance through regulation of these metabolic pathways. Also, C 75 altered neuronal ATP levels in a biphasic manner (decreasing initially, followed by a prolonged increase above control levels). The AMP-activated protein kinase (AMPK) activity was also influenced by C 75 . In human melanoma A-375 cells, C 75 inhibited cell growth through activation of caspase-dependent apoptosis .
In diet induced obese (DIO) mice, chronic C 75 treatment reduced food intake and increased energy expenditure due to increased fatty acid oxidation. C 75 significantly reduced adipose tissue. The reduced food intake was accompanied by an increase in amphetamine and cocaine-related transcript expression .
