| Common Name | 9,10-DHOME |

| Description | 9,10-Dihydroxy-12-octadecenoic acid (CAS: 263399-34-4), also known as 9,10-DHOME, is a derivative of linoleic acid diol and has been reported to be toxic in human's tissue preparations. 9,10-DHOME is a naturally occurring proliferator-activated receptor (PPAR) gamma2 ligand, which stimulates adipocytes and inhibits osteoblast differentiation. 9,10-DHOME is the epoxide hydrolase metabolite of the leukotoxin 9,10-EpOME. 9,10-EpOME act as a protoxin, with the corresponding epoxide hydrolase metabolite 9,10-DHOME, specifically exerting toxicity. Both 9,10-EpOME and 9,10-DHOME are shown to have neutrophil chemotactic activity. 9,10-DHOME suppresses 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 (PMID: 12021203 , 12127265 , 17435320 ). 9,10-DHOME is found in fruits and can be isolated from the seeds of Cucurbita pepo. |
