Metabolite Identification
Common Name12,13-DHOME
Description12,13-DHOME (CAS: 263399-35-5), also known as 12,13-dihydroxy-9-octadecenoic acid or 12,13-DiHOME, is the epoxide hydrolase metabolite of the leukotoxin 12,13-EpOME. 12,13-EpOME acts as a protoxin, with the corresponding epoxide hydrolase 12,13-DHOME specifically exerting toxicity. Both the EpOME and the DHOME are shown to have neutrophil chemotactic activity. 12,13-DHOME suppress the neutrophil respiratory burst by a mechanism distinct from that of respiratory burst inhibitors such as cyclosporin H or lipoxin A4, which inhibit multiple aspects of neutrophil activation. 12,13-DHOME is a derivative of the linoleic acid diol that has been reported to be toxic in human tissue preparations. 12,13-DHOME is a naturally occurring proliferator-activated receptor (PPAR) gamma2 ligand, which stimulates adipocytes and inhibits osteoblast differentiation (PMID: 17435320 , 12021203 , 12127265 ).
