(±)11(12)-EET

Description: (±)11(12)-EET is a fully racemic version of the R/S enantiomeric forms biosynthesized from arachidonic acid by cytochrome P450 enzymes.[1][2][3] A higher proportion of 11(R),12(S)-EET is produced by the CYP450 isoforms CYP2C23 and CYP2C24, while CYP2B2 produces a higher proportion of 11(S),12(R)-EET.[3] 11(12)-EET has been shown, along with 8(9)-EET, to play a role in the recovery of depleted calcium pools in cultured smooth muscle cells.[4] It also inhibits basolateral 18-pS potassium channels in the renal cortical collecting duct at a concentration of 100 nM.[5] 11(12)-EET (50 µg/kg per day) increases adhesion of isolated peripheral blood leukocytes in a chamber coated with P-selectin and ICAM-1 but does not affect choroidal neovascularization size following laser photocoagulation.[6] It also has anti-inflammatory, angiogenic, and cardioprotective properties.[7].
