Prostaglandin F2alpha 1,15-lactone

Prostaglandin F2alpha (PGF2alpha) 1,15-lactone is a lipid-soluble internal ester of PGF2alpha. Hydrolysis of the lactone readily produces free PGF2alpha in plasma. In rhesus monkeys, a total dose of 15 mg of PGF2alpha 1,15-lactone terminates early pregnancy, whereas PGF2alpha is ineffective.Formal Name: 9alpha,11alpha,15S-trihydroxy-prosta-5Z,13E-dien-1-oic acid, lambda-lactone.
