Novel oxylipins, referred to as docosanoids, have been derived from C₂₂ polyunsaturated fatty acids 7(S),17(S)-dihydroxy-8(E),10(Z),13(Z),15(E),19(Z)-Docosapentaenoic acid (7(S),17(S)-hydroxy DPA) is a DPA-derived analog of the 17(S)-dihydroxy series of docosanoids known as protectins. Protectin D₁, a DHA-derived dihydroxy fatty acid, exhibits potent anti-inflammatory activities. Potentially, 7(S),17(S)-hydroxy DPA demonstrates similar properties; however, its biological activity has yet to be determined.

7,17-Dihydroxy-8(E),10(Z),13(Z),15(E),19(Z)-docosapentaenoic acid ((2E,7S,8Z,10Z,13Z,15E,17S)-7,17-Dihydroxydocosa-2,8,10,13,15-pentaenoic acid) is an ester product.
