C75 is a novel, potent synthetic inhibitor of fatty acid synthase (FAS), which is used as a tool for studying fatty acid synthesis in metabolic disorders and cancer. C75 inhibits FAS activity and stimulates carnitine palmitoyltransferase-1 (CPT-1) in primary cortical neurons, consistent with its effects in peripheral tissues. C75 alters neuronal ATP levels and AMP-activated protein kinase (AMPK) activity. C75 displays anorectic effects. C75 induces apoptosis in MCF-7 xenografts and exhibits anti-tumor activity. Several downstream pathways are affected by C75 treatment, including glucose metabolism and acetyl-CoA carboxylase (ACC) phosphorylation. C75 modulates the levels of energy intermediates, thus, affecting the energy sensor AMPK.

Fatty Acid Synthase (FAS)
C75 inhibits PC3 cell growht with an IC50 of 35 μM at 24 h. C75 (10-50 μM) also reduces the growth of LNCaP spheroids in a concentration-dependent manner with an IC50 of 50 μM. (-)-C75 inhibits FAS activity and has a cytotoxic effect on tumor cell lines, without affecting food consumption. (+)-C75 inhibits CPT1 and its administration produces anorexia, suggesting that central inhibition of CPT1 is essential for the anorectic effect of C75. The differential activity of C75 enantiomers may lead to the development of potential new specific drugs for cancer and obesity.
C75 blocks fasting-induced c-Fos expression in the arcuate nucleus (Arc), lateral hypothalamic area (LHA), and paraventricular nucleus (PVN) 10–24 h after i.p. injection. Intraperitoneal administration of C75 at 30 mg/kg body weight inhibits food intake of mice by ≥95% within 2 h after i.p. injection. C75-treated DIO mice has a 50% greater weight loss, and a 32.9% increased production of energy because of fatty acid oxidation. C75 treatment of rodent adipocytes and hepatocytes and human breast cancer cells increases fatty acid oxidation and ATP levels by increasing CPT-1 activity, even in the presence of elevated concentrations of malonyl-CoA.
