Description
(±)12,13-DiHOME is the diol resulting from the soluble epoxide hydrolase opening of (±)12,13-EpOME. The mixture of the methyl ester of this diol and the 9,10 isomer are more cytotoxic than the methyl ester epoxides in renal proximal tubular cells.However, in renal cortical mitochondria, the conversion of the epoxide to 12,13-DiHOME appears to be part of the detoxification pathway that prevents mitochondrial dysfunction. This diol and the 9,10 isomer can be glucuronidated by human liver and intestinal microsomes as well as recombinant UGT2B7 through a hydroxyl group. High levels of LA-diol glucuronides have been found in the urine of humans with peroxisomal diseases. A mixture of the diols stimulates breast cancer cell proliferation in vitro and disrupts reproductive function in rats at relatively low concentrations.(±)12,13-DiHOME is supplied as a solution in methyl acetate. To change the solvent, simply evaporate the methyl acetate under a gentle stream of nitrogen and immediately add the solvent of choice. Solvents such as ethanol, DMSO, and dimethyl formamide purged with an inert gas can be used. The solubility of (±)12,13-DiHOME in these solvents is approximately 20 mg/ml
