18-Carboxy-dinor-LTE4

18-carboxy-dinor-LTE4 is a metabolite through lipid oxidation of Leukotriene E4 (LTE4).Leukotriene E4 (LTE4) is a cysteinyl leukotriene. Cysteinyl leukotrienes (CysLTs) are a family of potent inflammatory mediators that appear to contribute to the pathophysiologic features of allergic rhinitis. Nasal blockage induced by CysLTs is mainly due to dilatation of nasal blood vessels, which can be induced by the nitric oxide produced through CysLT1 receptor activation. LTE4, activate contractile and inflammatory processes via specific interaction with putative seven transmembrane-spanning receptors that couple to G proteins and subsequent intracellular signaling pathways. LTE4 is metabolized from leukotriene C4 in a reaction catalyzed by gamma-glutamyl transpeptidase and a particulate dipeptidase from kidney. (PMID: 12607939, 12432945, 6311078). Leukotrienes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. 18-carboxy-dinor-LTE4 is a metabolite through lipid oxidation of Leukotriene E4 (LTE4).Leukotriene E4 (LTE4) is a cysteinyl leukotriene.

Ergometrine maleate is a maleate salt resulting form the reaction of equimolar amounts of maleic acid and ergometrine. It is used in the active management of the third stage of labour, and to prevent or treat postpartum of postabortal haemorrhage caused by uterine atony: by maintaining uterine contraction and tone, blood vessels in the uterine wall are compressed and blood flow reduced. It has a role as an oxytocic and a diagnostic agent. It contains an ergometrine. An ergot alkaloid (ERGOT ALKALOIDS) with uterine and VASCULAR SMOOTH MUSCLE contractile properties.
