Source	There were reports of prolonged biological activity of chemically unstable prostaglandin I2, which suggested a possible transformation of prostaglandin I2 to a more stable metabolite with potent bioactivity Wong_PY et al.. Further investigations led to the discovery of 6-keto-prostaglandin E1.
Chemical Synthesis	Tanaka_T et al.
Metabolism	A potential role of 9-hydroxyprostaglandin dehydrogenase was demonstrated in the transformation of prostaglandin I2 to 6-keto-prostaglandin E1 Wong_PY et al..
Biological Activity	6-Keto-prostaglandin E1 is a stable metabolite. The compound inhibits platelet aggregation with activity comparable or greater than prostaglandin D2 although less potent than prostaglandin I2. Its vasodilatory and hypotensive activities, bronchodilatory property, and inhibition of gastric acid secretion were reported Moore_PK et al..
