Effect of the beta-2 adrenergic agonist fenoterol on the release of leukotrienes and prostaglandin D2 from human lung parenchyma. 1986

Ca++-ionophore and antigen challenge of human lung fragments caused a massive release of leukotrienes, whose relative proportions varied considerably and were dependent on the experimental conditions. A broncho-selective beta 2-adrenoceptor agonist fenoterol was able to prevent the antigen-induced leukotriene release completely, whereas the Ca++-ionophore induced leukotriene release was only moderately inhibited. The HPLC data were confirmed by SRS-A bioassay.

D000001 Calcimycin An ionophorous, polyether antibiotic from Streptomyces chartreusensis. It binds and transports CALCIUM and other divalent cations across membranes and uncouples oxidative phosphorylation while inhibiting ATPase of rat liver mitochondria. The substance is used mostly as a biochemical tool to study the role of divalent cations in various biological systems. 4-Benzoxazolecarboxylic acid, 5-(methylamino)-2-((3,9,11-trimethyl-8-(1-methyl-2-oxo-2-(1H-pyrrol-2-yl)ethyl)-1,7-dioxaspiro(5.5)undec-2-yl)methyl)-, (6S-(6alpha(2S*,3S*),8beta(R*),9beta,11alpha))-,A-23187,A23187,Antibiotic A23187,A 23187,A23187, Antibiotic

D013189 SRS-A A group of LEUKOTRIENES; (LTC4; LTD4; and LTE4) that is the major mediator of BRONCHOCONSTRICTION; HYPERSENSITIVITY; and other allergic reactions. Earlier studies described a "slow-reacting substance of ANAPHYLAXIS" released from lung by cobra venom or after anaphylactic shock. The relationship between SRS-A leukotrienes was established by UV which showed the presence of the conjugated triene. (From Merck Index, 11th ed) Slow Reacting Substance of Anaphylaxis
D015230 Prostaglandin D2 The principal cyclooxygenase metabolite of arachidonic acid. It is released upon activation of mast cells and is also synthesized by alveolar macrophages. Among its many biological actions, the most important are its bronchoconstrictor, platelet-activating-factor-inhibitory, and cytotoxic effects. 11-Dehydroprostaglandin F2alpha,PGD2,11-Dehydroprostaglandin F2 alpha,11 Dehydroprostaglandin F2 alpha,11 Dehydroprostaglandin F2alpha,D2, Prostaglandin,F2 alpha, 11-Dehydroprostaglandin,F2alpha, 11-Dehydroprostaglandin,alpha, 11-Dehydroprostaglandin F2
D016718 Arachidonic Acid An unsaturated, essential fatty acid. It is found in animal and human fat as well as in the liver, brain, and glandular organs, and is a constituent of animal phosphatides. It is formed by the synthesis from dietary linoleic acid and is a precursor in the biosynthesis of prostaglandins, thromboxanes, and leukotrienes.
