Annual Review of Biochemistry, 1975
AbstractThe prostaglandins are lipid‐soluble C20‐carboxylic acids containing a five‐membered ring, several oxygen function, and at least one double bond. They are found in animal organisms where they stimulate, inter alia, the smooth muscle. In the last decade more has been learned about the occurrence, biosynthesis, metabolism and pharmacological ...

A discussion of important aspects of the effects of prostaglandins on arteries must include (a) the nature of the receptors for the different humoral agents, (b) the potential modulatory role that endogenously produced prostaglandins may play when other vasoactive hormones are present, and (c) the potential for cell-to-cell transfer of substrates for ...

This is an explanation of 2 highly specific reductive processes for the interconversion of primary PGs (prostaglandins). The laboratory procedures are described in detail and the chemical structures of substances involved in the process are diagrammed. A stereospecific reduction of PGE to PGFalpha is described.

The introduction of dinoprost tromethamine (Prostin F2 Alpha) as an abortifacient in the second trimester of pregnancy represents the first clinical use of a prostaglandin. Various synthetic analogues of the naturally occurring derivatives are being employed investigationally in the treatment of peptic ulcer, hypertension, asthma, and hypercalcemia. In

Prostaglandins and Postmaturity
Australian and New Zealand Journal of Obstetrics and Gynaecology, 1977Summary: Levels of E and F prostaglandins in amniotic fluid of patients with prolonged pregnancy have been compared with levels of patients in the last 4 weeks of normal pregnancy. The mean F prostaglandin levels in patients going past term (1,293.3 ± 332.87 pg/ml) were considerably lower than those going into spontaneous labour at term (4,276.71 ± 1 ...

Abstract Freshly prepared solutions of prostaglandin E1 exhibit chemotactic activity against rabbit polymorphonuclear leucocytes harvested from the peritoneal cavity but are devoid of such activity either against similar cells obtained from the rat or against polymorphonuclear leucocytes obtained from the blood of the rabbit, rat and man.

Prostaglandin D2 (PGD2) is the endogenous sleep inducing substance in rats, mice, monkeys and probably in humans. PGD synthase (PGDS), the enzyme that produces PGD2 in the brain, is the key enzyme in sleep regulation. When the enzyme activity is inhibited by its specific inhibitor, SeCl4 in vivo, rats can no longer sleep.
