Steviol
Steviol is an ent-kaurane diterpenoid that is 5beta,8alpha,9beta,10alpha-kaur-16-en-18-oic acid in which the hydrogen at position 13 has been replaced by a hydroxy group. It has a role as an antineoplastic agent. It is a tetracyclic diterpenoid, a tertiary allylic alcohol, a monocarboxylic acid, a bridged compound and an ent-kaurane diterpenoid. It is a conjugate acid of a steviol(1-). Steviol is a natural product found in Ceriops decandra, Cucurbita, and other organisms with data available. Steviol is found in fruits. Steviol is isolated from Cucurbita maxima Rebaudioside B, D, and E may also be present in minute quantities; however, it is suspected that rebaudioside B is a byproduct of the isolation technique. The two majority compounds stevioside and rebaudioside, primarily responsible for the sweet taste of stevia leaves, were first isolated by two French chemists in 1931. Isolated from Cucurbita maxima Steviol is a major metabolite of the sweetening compound stevioside. Steviol slows renal cyst growth by reducing AQP2 expression and promoting AQP2 degradation[1].

Leukotriene A4
Leukotriene A4 (LTA4) is the first metabolite in the series of reactions leading to the synthesis of all leukotrienes. 5-Lipoxygenase (5-LO) catalyzes the two-step conversion of arachidonic acid to LTA4.The first step consists of the oxidation of arachidonic acid to the unstable intermediate 5-hydroperoxyeicosatetraenoic acid (5-HPETE), and the second step is the dehydration of 5-HPETE to form LTA4. Leukotriene A4, an unstable epoxide, is hydrolyzed to leukotriene B4 or conjugated with glutathione to yield leukotriene C4 and its metabolites, leukotriene D4 and leukotriene E4. The leukotrienes participate in host defense reactions and pathophysiological conditions such as immediate hypersensitivity and inflammation. Recent studies also suggest a neuroendocrine role for leukotriene C4 in luteinizing hormone secretion. (PMID: 10591081, 2820055). 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.
