Isoprostanes are prostaglandin (PG)-like products of free-radical induced lipid peroxidation. Although the isoprostanes derived from arachidonic acid are the best characterized, many other polyunsaturated fatty acids can form isoprostanes. iPF2α-VI is one of dozens of possible stereo- and…

Biosynthesis of LTA3 occurs from 5,8,11-eicosatrienoic acid via the 5-LO pathway{689} and it is the putative intermediate in the biosynthesis of 3-series leukotrienes. LTA3 as a free acid is highly unstable. The methyl ester is stable and can be readily hydrolyzed to the free acid as needed.

A dehydration product of tetranor-PGEM that can be measured as a surrogate for tetranor-PGEM levels in urine.

A purified enantiomer of (±)9-HETE resulting from non-enzymatic oxidation of arachidonic acid.

A DHA-derived product first identified in mouse inflammatory exudates; reduces neutrophil infiltration in vivo in both mouse peritonitis and dermal inflammation; enhances macrophage phagocytosis and efferocytosis.

(±)9-HETE is one of the six monohydroxy fatty acids produced by the non-enzymatic oxidation of arachidonic acid. The individual R and S isomers of racemic HETEs have been separated and identified using chiral phase HPLC. The racemic HETEs have been quantified as an index of lipid…

An internal standard for the quantification of PGF2α by GC- or LC-MS.

(±)8-HETE is one of the six monohydroxy fatty acids produced by the non-enzymatic oxidation of arachidonic acid.

A 5-series LO derived from EPA; contracts pulmonary parenchymal strips from guinea pig with similar potency to that of LXA4 and LXB4, yet does not exert the vasodilatory effects on aortic smooth muscle exhibited by LXA4 and LXB4.

A potential cytochrome P450 metabolite of N-arachidonoyl taurine that may activate TRPV1 and TRPV4.

A derivative of (±)8(9)-EET which is stable enough to ship and handle routinely.

Differs from the major microcystin variant LR with the substitution of alanine in place of the arginine; inhibits both PP1C and PP2A with an IC50 value of 0.3 nM.

A bioactive macrolide derived from sponges that binds monomeric actin, preventing actin polymerization both in vitro (Kd = 0.2 μM) and in cells (0.5 μM).

(±)14(15)-EET-d11 contains 11 deuterium atoms at the 16, 16', 17, 17', 18, 18' ,19, 19' ,20, 20, and 20 positions. It is intended for use as an internal standard for the quantification of (±)14(15)-EET (Item No. 50651) by GC- or LC-MS.

The diol resulting from the sEH opening of (±)11(12)-EET; contracts artery rings with approximately 70% of the magnitude of (±)11(12)-EET.

Less potent than AEA (Item No. 90050) at the CB1 receptor (Ki = 600 versus 90 nM); inhibits FAAH.

The lipoxins are trihydroxy fatty acids containing a 7,9,11,13-conjugated tetraene. LXA4 was first described as a metabolite of 15-HpETE and/or 15-HETE when added in vitro to isolated human leukocytes. The material obtained in this manner consists of at least four distinct isomers: 5(S), 6(S);…

(±)12-HETE is one of the six monohydroxy fatty acids produced by the non-enzymatic oxidation of arachidonic acid. The biological activity of (±)12-HETE is similar to that of its constituent enantiomers (Item Nos. 34560 and 34570). It aggregates neutrophils with an EC₅₀…

A potent, selective inhibitor of PKG (in vitro IC50 = 234 nM); cell-permeable and often used in intact cells to assess the role of PKG in signaling.

15-OxoETE is produced by oxidation of the 15-hydroxyl of 15-HETE. Whether this is a major pathway of 15-HETE metabolism is yet to be clearly established.

A metabolite of (±)12(13)-EpOME.

11-trans LTD4 is a C-11 double bond isomer of LTD4. LTD4 undergoes slow temperature-dependent isomerization to 11-trans LTD4 during storage. 11-trans LTD4 retains about 10-25 % of the potency for contraction of guinea pig ileum, trachea and parenchyma compared to LTD4. It exhibits an ED50 ranging…
