trans-Tetrahydro-4-methylene-2-octyl-5-oxo-3-furancarboxylic Acid is a well-known fatty acid synthase (FAS) inhibitor. Studies show that trans-Tetrahydro-4-methylene-2-octyl-5-oxo-3-furancarboxylic Acid is a cell cycle arrest inducer in hepatocellular carcinoma (HCC) cell lines. It has also been shown to blocks resistin-induced increases in lipid accumulation by human macrophages.
ChEBI: (2R,3S)-C75 is a 4-methylidene-2-octyl-5-oxotetrahydrofuran-3-carboxylic acid that has 2R,3S-configuration. It is an enantiomer of a (2S,3R)-C75.
c 75 is an inhibitor of fatty acid synthase [1].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 [1].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 [1]. 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 [2]. in human melanoma a-375 cells, c 75 inhibited cell growth through activation of caspase-dependent apoptosis [3].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 [4].
