	11-trans Leukotriene C4 (11-trans LTC4) is a C-11 double bond isomer of LTC4. LTC4 undergoes slow temperature-dependent isomerization to 11-trans LTC4 during storage. 11-trans LTC4 is produced in smaller amounts relative to LTC4 in ionophore-stimulated HMC-1 cells (a human mast cell line) and equine eosinophils, but not in human neutrophils or RBL-1 cells. It is nearly equipotent with LTC4 for contraction of guinea pig parenchymal and ileum. In a radioligand binding assay using guinea pig ileum ...

	Produced by neutrophils, macrophages, mast cells, and by transcellular metabolism in platelets, leukotriene C4 (LTC4) is the parent cysteinyl leukotriene formed by the LTC4 synthase-catalyzed conjugation of glutathione to LTA4. It is one of the constituents of slow-reacting substance of anaphylaxis (SRS-A) and exhibits potent smooth muscle contracting activity. LTC4, however, is rapidly metabolized to LTD4 and LTE4, which makes the characterization of LTC4 pharmacology difficult. N-methyl Leukot...

T37262	14,15-Leukotriene E4 14,15-Leukotriene E4
	Leukotrienes (LTs) are a group of acute inflammatory mediators derived from arachidonic acid in leukocytes. The majority of these metabolites are formed through the 5-lipoxygenase (5-LO) pathway. 14,15-LTE4 is a metabolite of 14,15-LTC4 and 14,15-LTD4, an alternate class of LTs synthesized by a pathway involving the dual actions of 15- and 12-LOs on arachidonic acid via 15-HpETE and 14,15-LTA4 intermediates. These metabolites are classified as eoxins because they are formed mostly by eosinophils...

T38128	Leukotriene D4 Leukotriene D4 MaxSpec® Standard,LTD4
	Leukotriene D4 (LTD4) is one of the constituents of slow-reacting substance of anaphylaxis (SRS-A) produced by the metabolism of LTC4 by γ-glutamyl transpeptidase. It is the first cysteinyl-leukotriene metabolite of LTC4 . Like LTC4, LTD4-induced bronchoconstriction and enhanced vascular permeability contribute to the pathogenesis of asthma and acute hypersensitivity. LTD4 is equipotent to LTC4 in its biological activities, except that LTD4 is nearly 100-fold more effective in the contraction of...
T28251	ONO-8809 ONO8809
	ONO-8809 is a thromboxane A2 receptor antagonist. ONO-8809 inhibited the LTC4-induced airway hyperresponsiveness to histamine in a dose-dependent manner. Macrophage accumulation and matrix metalloproteinase-9 (MMP-9) activity in the stroke-negative area i

T38062	N-acetyl Leukotriene E4 N-acetyl Leukotriene E4
	N-acetyl LTE4 is the major inactive metabolite of LTE4 found in bile. This route of metabolism is prominent in the rat, but of minor importance in humans. N-acetyl LTE4 is 100 times less potent than LTC4 as a vasoconstricting agent. In healthy human subjects urinary excretion of N-acetyl LTE4 is about 1.5 nmol/mol creatinine, which is considerably less than that of LTE4 (12 nmol/mol creatinine).
T38129	Leukotriene F4 LTF4
	LTF4 is a cysteinyl-leukotriene produced in vitro, but not reported to date in vivo. It is formed by the incubation of LTE4 with γ-glutamyl transpeptidase and glutathione. LTF4 is a weak agonist in its ability to contract vascular smooth muscle. [1] The rank order of potency of the cysteinyl-leukotrienes to contract vascular smooth muscle is LTD4 > LTC4 > LTE4 >> LTF4. [1] [2]
T37331	Pyrrophenone
	The group IVA phospholipase A2 (PLA2), known as calcium-dependent cytosolic PLA2 (cPLA2), selectively releases arachidonic acid (AA) from membrane phospholipids, playing a central role in initiating the synthesis of prostaglandins (PGs) and leukotrienes (LTs). Pyrrophenone inhibits cPLA2α with an IC50 of 4.2 nM in enzyme assays and potently blocks the release of AA and the production of PGE2 and LTC4 in cells (IC50 = 24, 25, and 14 nM, respectively). Its action is reversible and selective, as py...
