    5(Z),11(Z),14(Z)-Eicosatrienoic acid

    Sciadonic acid

    		 Apolipoprotein Inflammation/Immunology
    5(Z),11(Z),14(Z)-Eicosatrienoic acid (Sciadonic acid), a polyunsaturated fatty acid sourced from maritime pine seed oil, gymnospermae leaves and seeds, and freshwater gastropods, has been shown to reduce high-density lipoprotein and ApoA1 levels in transgenic mice expressing human ApoA1 when included in their diet. In vitro studies indicate that it diminishes cholesterol efflux, and when applied topically in its methyl ester form, it alleviates inflammatory processes, likely by displacing arachidonic acid from phospholipid pools and lowering concentrations of downstream inflammatory mediators such as prostaglandin E2 and leukotrienes.

    Leukotriene B5

    LTB5

    		 Leukotriene Receptor Cancer
    Leukotriene B5 (LTB5) is a leukotriene with diverse biological activities. It is a metabolite of eicosapentaenoic acid formed through the 5-lipoxygenase (5-LO) pathway. LTB5 increases contraction of bullfrog lung strips ex vivo in a concentration-dependent manner. In vivo, LTB5 (100 nM) reduces tumor volume in mice injected with Tm1 murine melanoma cells. LTB5 also elicits chemokinesis and lysosomal enzyme release from polymorphonuclear leukocytes (PMNLs) 20- to 30-fold less, and induces platelet aggregation 8-fold less, potently than LTB4.

    PL265

    		Endogenous Metabolite Opioid Receptor Leukotriene Receptor Neurological Disease Inflammation/Immunology
    PL265 is an orally active dual enkephalinase inhibitor. PL265 is a prodrug of PL254, which can simultaneously and efficiently inhibit neutral endopeptidase (Neprilysin) and Aminopeptidase N. PL265 can effectively protect and significantly increase the local concentration of enkephalins (such as Met-Enkephalin and Leu-Enkephalin) released by cells at the pain or inflammation sites, thereby activating μ and δ opioid receptors to produce a potent analgesic effect. PL254 can also inhibit leukotriene A4 hydrolase (LTA4H), which may contribute to its additional anti-inflammatory effect by reducing the production of pro-inflammatory mediator leukotriene B4 (LTB4). PL265 can be used in non-addictive chronic pain research .

    L-669083

    		FLAP Inflammation/Immunology
    L-669083 is a leukotriene biosynthesis inhibitor whose structure is based on a mixture of indole and quinoline. In this study, a potent radioiodinated photoaffinity analog of L-689,037, [125I] L-691,678, was developed and characterized for immunoprecipitation studies showing that the quindole series of leukotriene biosynthesis inhibitors directly interact with FLAP. In addition, the results showed that MK-886, L-674,573, and L-689,037 competed with [125I] L-691,678 and [125I] L-669083 for binding to FLAP in a concentration-dependent manner, indicating that these three leukotriene biosynthesis inhibitors share a binding site on FLAP, further demonstrating that FLAP is a suitable target for structurally diverse leukotriene biosynthesis inhibitors.

    A63162

    		Lipoxygenase Leukotriene Receptor Inflammation/Immunology
    A63162 is a specific 5-lipoxygenase (5-LOX) inhibitor. A63162 inhibits mitogen (PHA)-induced horse mononuclear cell (BMC) proliferation and inhibits Calcimycin (HY-N6687)-induced leukotriene LTB4 synthesis at the same concentration. A63162 can be used in the study of chronic obstructive pulmonary disease, arthritis and inflammatory bowel disease .

    Lipoxin B4 methyl ester

    LXB4 methyl ester

    		 Drug Intermediate Leukotriene Receptor Metabolic Disease
    Lipoxin B4 (LXB4) methyl ester is a lipid soluble prodrug form of the transcellular metabolite LXB4. LXB4 is a positional isomer of LXA4 produced by the metabolism of 15-HETE or 15-HpETE by human leukocytes. At a concentration of 100 nM, LXB4 inhibits polymorphonuclear leukocyte (PMN) migration stimulated by leukotriene B4 (LTB4; Item No. 20110) and inhibits LTB4-induced adhesion of PMNs with an IC50 value of 0.3 nM.

    tHGA

    		Lipoxygenase Inflammation/Immunology
    tHGA is a compound with anti-inflammatory activity and has the activity to inhibit soybean 15-LOX. tHGA showed significant inhibitory effects in experiments on human leukocytes, with an IC50 value of 0.42 μM, which is close to the effect of commonly used standard NDGA. tHGA concentration-dependently inhibits the synthesis of 5-LOX products, especially the cysteine leukotriene LTC(4), with an IC50 value of 1.80 μM. and showed no cytotoxicity. The anti-inflammatory effects of tHGA do not appear to be through redox or metal chelation mechanisms, as the compound was negative in these bioactivity tests. tHGA works through a dual LOX/COX inhibition mechanism and has higher selectivity for 5-LOX and COX-2, with an IC50 value of 0.40 μM .

    AM-643

    		FLAP Inflammation/Immunology
    AM-643 is a FLAP inhibitor with human IC50 of 2 nM, oral activity, and dermal activity.AM-643 selectively inhibits FLAP, reduces leukotriene biosynthesis and reduces inflammatory ear swelling.AM-643 can be used for the research of skin disorders involving leukotriene production .
