5,6-DiHET lactone is a lactonized form of 5,6-EET and 5,6-DiHET. In solution, 5(6)-EET degrades into 5(6)-DiHET and 5(6)-δ-lactone, which can be converted to 5(6)-DiHET and quantified by GC-MS. 5,6-DiHET potently induces vasodilation of isolated canine coronary arterioles, with 41 and 100% inhibition occurring at 0.01 and 100 pM, respectively. It also induces vasodilation in isolated human microvessels and increases intracellular calcium levels in a dose-dependent manner, an effect that can be blocked by the nitric oxide scavenger L-NAME .

The phospholipases are an extensive family of lipid hydrolases that function in cell signaling, digestion, membrane remodeling, and as venom components. The calcium-independent phospholipases (iPLA2) are a PLA2 subfamily closely associated with the release of arachidonic acid in response to physiologic stimuli. (R)-Bromoenol lactone ((R)-BEL) is an irreversible, chiral, mechanism-based inhibitor of calcium-independent phospholipase γ (iPLA2γ). Unlike (S)-BEL, (R)-BEL does not inhibit iPLA2β except at high doses of 20-30 μM. (R)-BEL inhibits human recombinant iPLA2γ with an IC50 of approximately 0.6 μM.

N-(3-hydroxy-7-cis tetradecenoyl)-L-Homoserine lactone is a long-chain N-acyl-homoserine lactone (AHL) produced by some Gram-negative bacteria and is involved in quorum sensing. Quorum sensing enables bacteria to change gene expression based on cues from nearby bacteria and from eukaryotic hosts about nutrients, environmental conditions, or threats. Due to the benefit of quorum sensing for bacterial survival, quorum sensing molecules are potential targets for controlling bacterial infections. In mouse and human leukocyte immunoassays using LPS-stimulated macrophages, N-(3-hydroxy-7-cis tetradecenoyl)-L-homoserine lactone did not have an effect on cytokine or antibody production.

N-3-hydroxydecanoyl-DL-Homoserine lactone is a bacterial quorum-sensing molecule.1It activates SdiA (EC50= 0.6 μM), a transcription factor that detects N-acyl homoserine lactones (AHLs), in the 14028 pJNS25 strain ofS. enterica.2 1.Fekete, A., Frommberger, M., Rothballer, M., et al.Identification of bacterial N-acylhomoserine lactones (AHLs) with a combination of ultra-performance liquid chromatography (UPLC), ultra-high-resolution mass spectrometry, and in-situ biosensorsAnal.

(±)5(6)-DiHET lactone is a 1,5 cyclic ester derived from (±)5(6)-DiHET , which, in turn, is a potential derivative of epoxidation of arachidonic acid at the α-5 double bond. (±)4(5)-DiHDPA lactone is a derivative of docosahexaenoic acid that is analogous to (±)5(6)-DiHET lactone. It is the 1,4 cyclic ester derived from (±)4(5)-DiHDPA, which is produced by epoxidation of DHA at the α-4 double bond. Its biological activity is unknown.

Eicosapentaenoic acid is metabolized, in part, through cytochrome P450-catalyzed epoxidation followed by conversion to the vicinal diols by epoxide hydrolases. (±)5(6)-DiHETE is a possible metabolite produced from EPA following epoxidation of the α-5 double bond. (±)5(6)-DiHETE lactone is a 1,5 cyclic ester derived from (±)5(6)-DiHETE. While its biological activity is unknown, the selective capacity of (±)5(6)-DiHETE to form this lactone can be utilized to specifically quantify (±)5(6)-DiHETE in biological samples.

N-3-oxo-hexadecanoyl-L-Homoserine lactone is an unusual, substituted, long-chain N-acyl-homoserine lactone (AHL) produced by some bacteria, including strains of Agrobacterium vitis and Pseudomonas.
