prostaglandins
Let an agent explain prostaglandins and their biochemistry, relay physiological roles and drug uses in general terms from pharmacology references, describe how NSAIDs act on them, and route personal medication questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain prostaglandins and their biochemistry, relay physiological roles and drug uses in general terms from pharmacology references, describe how NSAIDs act on them, and route personal medication questions to clinicians.
A group of lipid signalling compounds derived from arachidonic acid through cyclooxygenase enzymes, built on the twenty-carbon prostanoic acid skeleton and including series such as PGE2, PGD2, PGF2 alpha and PGI2 with derivatives such as glyceryl esters, that act locally as hormone-like mediators of inflammation, pain, fever, blood flow, platelet function, gastric protection, labour and many other processes; prostaglandin synthesis is blocked by aspirin and other NSAIDs, and synthetic prostaglandins are used as drugs in obstetrics, gastroenterology, ophthalmology and cardiology.
What it is for: Not applicable; a class of signalling lipids.
It can be explain biochemistry; relay physiological roles; describe drug uses and NSAIDs; route personal questions.

How it is recognised
Cyclooxygenase-derived eicosanoids

What the second pass must settle

- How should pharmacology references be linked?
- The registry entry has merged aliases with systematic names and esters; should they be split off?
