ABSTRACT
Sulindac sulphide (SS), a cancer preventative metabolite of sulindac, inhibits mitochondrial oxidation of a range of metabolic substrates including fatty acids and intermediates of the tricarboxylic acid cycle. Metabolic inhibition may contribute to the anticancer action of SS; so authors have extended this work to see if other NSAIDS inhibit oxidative metabolism in liver mitochondria. SS and close structural analogues were the most potent inhibitors of mitochondrial glutamate oxidation. Inhibition of mitochondrial respiration may contribute to the anti-cancer action of these compounds by causing accumulation of short chain fatty acids that promote differentiation.

    The bioavailability of sulindac (SDC), a nonsteroidal anti-inflammatory drug, is low due to poor aqueous solubility and poor dissolution rate. For this reason it is necessary to enhance the solubility and enhance dissolution of the drug by dispersing SDC in polyethylene glycols 6000 (PEG 6000)...
