Prostaglandin A1 (PGA1) was first isolated as a dehydration product of the PGE1 compounds found in human semen. 15-keto PGA1 is a metabolite of PGA1, produced by 15-hydroxy PG dehydrogenase. It can be produced from PGA1 in pig lung, trachea, aorta, and pulmonary artery tissue preparations. 15-keto PGA1, given at a concentration of 6 μM, causes vasoconstriction of rabbit lung that is comparable to that induced by angiotensin II.
ChEBI: 15-dehydroprostaglandin A1 is a member of the class of prostaglandins A obtained by oxidation of the 15-hydroxy group of prostaglandin A1 to the corresponding ketone. It has a role as an Escherichia coli metabolite and a human metabolite. It is functionally related to a prostaglandin A1. It is a conjugate acid of a 15-dehydroprostaglandin A1(1-).
