Values are mean ± SE.
5,6-EET recoveries with the implemented procedure are roughly 25%. Loss of this compound is apparently through internal cyclization to the 5,6-delta lactone, not hydrolysis to the 5,6-DHET (29). “%” indicates the percentage of specific EPOMEs, DHOMEs, EETs, and DHETs in total EPOMEs, DHOMEs, EETs, and DHETs respectively.
Abbreviations: SHRSP, stroke-prone spontaneously hypertensive rats; EET, epoxyeicosatrienoic acid; DHET, dihydroxyeicosatrienoic acids; AUDA, adamantyl dodecanoic acid; EPOME, epoxyoctadecanoic acid; DHOME, dihydroxyoctadecanoic acid.
