Beschreibung
Protectin D₁ (also known as neuroprotectin D₁ when produced in neuronal tissues) is a DHA-derived dihydroxy fatty acid that exhibits potent protective and anti-inflammatory activities.^1,2,3 10(S),17(S)-DiHDHA is a DHA metabolite, also referred to as protectin DX (PDX).⁴ It is produced by an apparent double lipoxygenase (LO)-mediated reaction in murine peritonitis exudates, in suspensions of human leukocytes, or by soybean 15-LO incubated with DHA.^1,4 It differs from protectin D₁ with respect to the stereochemistry of the C-10 hydroxyl and the double bond configuration at the 13 and 15 positions. 10(S),17(S)-DiHDHA blocks neutrophil infiltration in murine peritonitis by 20-25% at a dose of 1 ng/mouse.¹ It also inhibits platelet activation by both impairing thromboxane (TX) synthesis and TX receptor activation.^4,5
Definition
ChEBI: (4Z,7Z,10S,11E,13Z,15E,17S,19Z)-10,17-dihydroxydocosahexaenoic acid is a dihydroxydocosahexaenoic acid that is (4Z,7Z,11E,13Z,15E,19Z)-docosahexaenoic acid in which the two hydroxy substituents are located at positions 10 and 17 (the 10S,17S-stereoisomer). A natural isomer of protectin D1, one of the specialised proresolving mediators. It has a role as an anti-inflammatory agent and a human xenobiotic metabolite. It is a dihydroxydocosahexaenoic acid, a secondary allylic alcohol and a protectin.
