Prostacyclin sodium salt

CAS 61849-14-7

Prostacyclin was first described as an unstable product made from prostaglandin intermediates by material from arteries. It inhibited platelet aggregation in the original experiments, showing that the vessel wall could contribute a chemical signal rather than simply provide a surface for blood to pass over. The sodium salt identifies a form of the organic molecule; it does not stop the structure from reacting with water. Hydrolysis can leave a product that provides evidence of earlier prostacyclin formation without being the original signal. This difference matters both to experiments and to the history of formulated epoprostenol medicines. To interpret a result, researchers must distinguish what was initially present, how long it persisted, and which chemical species the experiment actually detected in the sample.
