CompoundDescription
dinoprostoneThe most common and most biologically active of the mammalian prostaglandins. It exhibits most biological activities characteristic of prostaglandins and has been used extensively as an oxytocic agent. The compound also displays a protective effect on the intestinal mucosa.
dinoprostA naturally occurring prostaglandin that has oxytocic, luteolytic, and abortifacient activities. Due to its vasocontractile properties, the compound has a variety of other biological actions.
epoprostenolA prostaglandin that is a powerful vasodilator and inhibits platelet aggregation. It is biosynthesized enzymatically from PROSTAGLANDIN ENDOPEROXIDES in human vascular tissue. The sodium salt has been also used to treat primary pulmonary hypertension (HYPERTENSION, PULMONARY).
11-hydroxy-5,8,12,14-eicosatetraenoic acidRN given refers to cpd without isomeric designation
arachidonic acidAn 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.
prostaglandin h2A cyclic endoperoxide intermediate produced by the action of CYCLOOXYGENASE on ARACHIDONIC ACID. It is further converted by a series of specific enzymes to the series 2 prostaglandins.
thromboxane a2An unstable intermediate between the prostaglandin endoperoxides and thromboxane B2. The compound has a bicyclic oxaneoxetane structure. It is a potent inducer of platelet aggregation and causes vasoconstriction. It is the principal component of rabbit aorta contracting substance (RCS).

thromboxane b2A stable, physiologically active compound formed in vivo from the prostaglandin endoperoxides. It is important in the platelet-release reaction (release of ADP and serotonin).
12-hydroxy-5,8,10-heptadecatrienoic acidmetabolite of arachidonic acid in blood platelet suspension; RN given refers to cpd without isomeric designation
15-hydroxy-5,8,11,13-eicosatetraenoic acidpotent & selective inhibitor of platelet lipoxygenase; RN given refers to cpd without isomeric designation
15-deoxy-delta(12,14)-prostaglandin j215-deoxy-PGJ2 is also available; check for double bonds (indicated by delta) at 12 and 14 positions
tetranorprostaglandin E1urinary metabolite of prostaglandins E
prostaglandin d2The 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.
