9(R)-HODE is a monohydroxy fatty acid and metabolite of linoleic acid. It is formed from linoleic acid by COX and lipoxygenase (LO).9(R)-HODE induces chemotaxis, increases the levels of chemokine (C-C motif) receptor 9 (CCR9) and chemokine (C-X-C motif) receptor 4 (CXCR4), and inhibits IL-6 release in primary human monocytes. It inhibits CD3α- and CD28-induced proliferation of isolated human peripheral blood lymphocytes when used at a concentration of 25 μg/mL.
ChEBI: 9(R)-HODE is a 9-HODE in which the 9-hydroxy group has R-stereochemistry. It is a conjugate acid of a 9(R)-HODE(1-). It is an enantiomer of a 9(S)-HODE.
