(±)11(12) eet

(±)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 when used 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]

(±)11(12)-EET methyl ester (11,12-EET methyl ester) 是一种环氧二十碳三烯酸 (EET)。EET 是一种内源性脂质信号分子，具有心脏保护和血管扩张功能。(±)11(12)-EET methyl ester 可以结合并激活 GPR132，增强小鼠和斑马鱼的造血诱导及移植能力。

(±)11(12)-EET-d11 Methyl ester 是 (±)11(12)-EET methyl ester 的氘代物。它是 11,12-环氧二十碳三烯酸 (11,12-EET) 的甲基化衍生物，但无法诱导 G 蛋白偶联受体 GPR132 的 β-arrestin 募集，也不增强造血干细胞和祖细胞 (HSPC) 标志物的表达。11,12-EET-methyl ester 被用作研究 11,12-EET 的结构-功能关系的阴性对照，促进分析氧化脂肪酸-GPR132 信号轴在造血中的作用。

(±)11(12)-EET Ethanolamide是一种Anandamide的可能代谢产物，由细胞色素 P450 (CYP450) 酶催化生成。

Epoxyeicosatrienoic acids (EETs), such as 11(12)-EET and 14(15)-EET, are cytochrome P450 metabolites of arachidonic acid that have been identified as endothelium-derived hyperpolarizing factors with vasodilator activity. 14,15-EE-5(Z)-E is a structural analog of 14,15-epoxyeicosatrienoic acids (14,15-EET) that antagonizes EET-induced relaxation of vascular smooth muscle. Relaxation of U46619-constricted bovine arteries by 14,15-EET could be inhibited approximately 80% by 14,15-EE-5(Z)-E at a concentration of 10 μM. 14,15-EE-5(Z)-E does not appear to antagonize nitric oxide- or iloprost-mediated vascular relaxation.

(±)-11(12)-DiHET is an oxylipin. 11(S),12(S)-DiHET and 11(R),12(R)-DiHET are vicinal diols formedviaenzymatic hydration of 11(12)-EET by cytosolic or soluble epoxide hydrolases in a non-stereoselective manner.1,2,3(±)11(12)-DiHET MaxSpec standard is a quantitative grade standard of (±)11(12)-DiHET that has been prepared specifically for mass spectrometry and related applications where quantitative reproducibility is required. The solution has been prepared gravimetrically and is supplied in a deactivated glass ampule sealed under argon. The concentration was verified by comparison to an independently prepared calibration standard. This (±)11(12)-DiHET MaxSpec standard is guaranteed to meet identity, purity, stability, and concentration specifications and is provided with a batch-specific certificate of analysis. Ongoing stability testing is performed to ensure the concentration remains accurate throughout the shelf life of the product.Note: The amount of solution added to the vial is in excess of the listed amount. Therefore, it is necessary to accurately measure volumes for preparation of calibration standards. Follow recommended storage and handling conditions to maintain product quality.
