Natural Product Identification
Common Name6-Ketoprostaglandin E1
Description6-Ketoprostaglandin E1, also known as 6-keto-pge1, belongs to the class of organic compounds known as prostaglandins and related compounds. These are unsaturated carboxylic acids consisting of a 20 carbon skeleton that also contains a five member ring, and are based upon the fatty acid arachidonic acid. Thus, 6-ketoprostaglandin E1 is considered to be an eicosanoid lipid molecule. A prostaglandin E that is prostaglandin E1 bearing a keto substituent at the 6-position. 6-Ketoprostaglandin E1 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 6-Ketoprostaglandin E1 was first documented in 1980 (PMID: 6258185). In humans, 6-ketoprostaglandin E1 is involved in mefenamic acid action pathway (PMID: 3186779) (PMID: 3075239) (PMID: 3472253) (PMID: 3912001).
