Chemical Structure
8(9)-EET
- CAS No.: 82864-43-5
- Formula:C20H32O3
- Molecular Weight:320.47
InChIKey: DBWQSCSXHFNTMO-QJVNBQAESA-N
SMILES: CCCCC/C=C\C/C=C\C[C@H]1[C@H](O1)C/C=C\CCCC(O)=O
Biological Activity: 8(9)-EET is one of the main metabolites produced by the metabolism of arachidonic acid (HY-109590) through the cytochrome P450 epoxide pathway. 8(9)-EET is an effective substrate for COX-1 and COX-2. 8(9)-EET activates PPARα in HEK293 cells and inhibits the activity of NF-κB induced by IL-1β in a PPARα-dependent and -independent manner. The (8S,9R)-isomer of 8(9)-EET ([(8S,9R)-EET]) causes vasoconstriction, thereby reducing renal plasma flow and glomerular filtration rate[1][2][3][4][5].
