| leukotriene a4 | (2s-(2 alpha,3 beta(1e,3e,5z,8z)))-3-(1,3,5,8-tetradecatetraenyl)oxiranebutanoic acid. An unstable allylic epoxide, formed from the immediate precursor 5-hpete via the stereospecific removal of a proton at c-10 and dehydration. Its biological actions are determined primarily by its metabolites, i.e., leukotriene b4 and cysteinyl-leukotrienes. Alternatively, leukotriene a4 is converted into leukotriene c4 by glutathione-s-transferase or into 5,6-di-hete by the epoxide-hydrolase. (12 Dec 1998) |

The conjugation product of leukotriene a4 and glutathione. It is the major arachidonic acid metabolite in macrophages and human mast cells as well as in antigen-sensitised lung tissue. It stimulates mucus secretion in the lung, and produces contractions of nonvascular and some vascular smooth muscle. Chemical name: Glycine, N-(S-(1-(4-carboxy-1-hydroxybutyl)-2,4,6,9-pentadecatetraenyl)-N-L-gamma-glutamyl-L-cysteinyl)-, (R-(R*,S*-(E,E,Z,Z)))- (12 Dec 1998) |

It is generated from leukotriene c4 after partial hydrolysis of the peptide chain, i.e., cleavage of the gamma-glutamyl portion. Its biological actions include stimulation of vascular and nonvascular smooth muscle, and increases in vascular permeability. Chemical name: Glycine, N-(S-(1-(4-carboxy-1-hydroxybutyl)-2,4,6,9-pentadecatetraenyl)-L-cysteinyl)-, (R-(R*,S*-(E,E,Z,Z)))- (12 Dec 1998) |

A biologically active principle of srs-a that is formed from leukotriene d4 via a peptidase reaction that removes the glycine residue. The biological actions of lte4 are similar to ltc4 and ltd4. Chemical name: 7,9,11,14-Eicosatetraenoic acid, 6-((2-amino-2-carboxyethyl)thio)-5-hydroxy-, (5S-(5R*,6S*(S*),7E,9E,11Z,14Z))- (12 Dec 1998) |

| leukotrienes | A family of biologically active compounds derived from arachidonic acid by oxidative metabolism through the 5-lipoxygenase pathway. They participate in host defense reactions and pathophysiological conditions such as immediate hypersensitivity and inflammation. They have potent actions on many essential organs and systems, including the cardiovascular, pulmonary, and central nervous system as well as the gastrointestinal tract and the immune system. (12 Dec 1998) |
| receptors, leukotriene | Cell-surface receptors that bind leukotrienes with high affinity and trigger intracellular changes influencing the behaviour of cells. The leukotriene receptor subtypes have been tentatively named according to their affinities for the endogenous leukotrienes ltb4, ltc4, ltd4, and lte4. (12 Dec 1998) |
|---|---|
| receptors, leukotriene b4 | A class of cell surface leukotriene receptors with a preference for leukotriene b4. Leukotriene b4 receptor activation influences chemotaxis, chemokinesis, adherence, enzyme release, oxidative bursts, and degranulation in polymorphonuclear leukocytes. There are at least two subtypes of these receptors. Some actions are mediated through the inositol phosphate and diacylglycerol second messenger systems. (12 Dec 1998) |

| leukotriene |
A type of chemical involved in inflammation. Leukotrienes seem to play a particularly important role in the inflammation associated with asthma. Recently some asthma medicines have been developed that work to reduce leukotrienes or their effects (these are called "leukotriene modifiers" or "leukotriene inhibitors").
