C19H28O8 (384.1784)

Artesunate is an artemisinin derivative that is the hemisuccinate ester of the lactol resulting from the reduction of the lactone carbonyl group of artemisinin. It is used, generally as the sodium salt, for the treatment of malaria. It has a role as an antimalarial, a ferroptosis inducer and an antineoplastic agent. It is an artemisinin derivative, a sesquiterpenoid, a dicarboxylic acid monoester, a cyclic acetal, a semisynthetic derivative and a hemisuccinate. Artesunate is indicated for the initial treatment of severe malaria. The World Health Organization recommends artesunate as first line treatment for severe malaria. Artesunate was developed out of a need for a more hydrophilic derivative of [artemisinin]. Artesunate was granted FDA approval on 26 May 2020. Artesunic acid is a natural product found in Artemisia apiacea, Acronychia pubescens, and Artemisia carvifolia with data available. Artesunate is a water-soluble, semi-synthetic derivative of the sesquiterpine lactone artemisinin with anti-malarial, anti-schistosomiasis, antiviral, and potential anti-neoplastic activities. Upon hydrolysis of artesunates active endoperoxide bridge moiety by liberated heme in parasite-infected red blood cells, reactive oxygen species and carbon-centered radicals form, which have been shown to damage and kill parasitic organisms. Additionally, in vitro studies demonstrate that this agent induces DNA breakage in a dose-dependent manner. Artesunate has also been shown to stimulate cell differentiation, arrest the cell cycle in the G1 and G2/M phases, inhibit cell proliferation, and induce apoptosis through mitochondrial and caspase signaling pathways. Artemisinin is isolated from the plant Artemisia annua. artesunate is a mineral. A water-soluble, semi-synthetic derivative of the sesquiterpene lactone artemisinin with anti-malarial, anti-schistosomiasis, antiviral, and potential anti-neoplastic activities Artesunate is part of the artemisinin group of drugs that treat malaria. It is a semi-synthetic derivative of artemisinin that is water-soluble and may, therefore, be given by injection. It is on the World Health Organizations List of Essential Medicines, the most effective and safe medicines needed in a health system (DrugBank).

20-Trihydroxy-leukotriene-B4

(5R,6Z,8E,10E,12S,14Z)-5,12,20,20,20-pentahydroxyicosa-6,8,10,14-tetraenoic acid

C20H32O7 (384.2148)

20-trihydroxy-leukotriene-B4 is the metabolite of lipid omega-oxidation of leukotriene B4 (LTB4). LTB4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Omega-oxidation is the major pathway for the catabolism of leukotriene B4 in human polymorphonuclear leukocytes. Leukotrienes are metabolites of arachidonic acid derived from the action of 5-LO (5-lipoxygenase). The immediate product of 5-LO is LTA4 (leukotriene A4), which is enzymatically converted into either LTB4 (leukotriene B4) by LTA4 hydrolase or LTC4 (leukotriene C4) by LTC4 synthase. The regulation of leukotriene production occurs at various levels, including expression of 5-LO, translocation of 5-LO to the perinuclear region, and phosphorylation to either enhance or inhibit the activity of 5-LO. Biologically active LTB4 is metabolized by omega-oxidation carried out by specific cytochrome P450s (CYP4F) followed by beta-oxidation from the omega-carboxy position and after CoA ester formation (PMID: 7649996, 17623009, 2853166, 6088485). 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. 20-trihydroxy-leukotriene-B4 is the metabolite of lipid omega-oxidation of leukotriene B4 (LTB4). LTB4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Omega-oxidation is the major pathway for the catabolism of leukotriene B4 in human polymorphonuclear leukocytes.

The regulation of leukotriene production occurs at various levels, including expression of 5-LO, translocation of 5-LO to the perinuclear region and phosphorylation to either enhance or inhibit the activity of 5-LO. Biologically active LTB4 is metabolized by w-oxidation carried out by specific cytochrome P450s (CYP4F) followed by beta-oxidation from the w-carboxy position and after CoA ester formation.
