(+)-Cloprostenol is a synthetic analog of prostaglandin F_2α (PGF_2α). It is an FP receptor agonist and a potent luteolytic agent in rats and hamsters. (+)-Cloprostenol is the optically active, 15(R) enantiomer of cloprostenol responsible for the majority of its biological activity. It is 200 times more potent than PGF_2α in terminating pregnancy when given subcutaneously at a daily dose of 0.125 μg/kg in rats and hamsters, without the side effects associated with PGF_2α. (+)-Cloprostenol was also shown to be a potent inhibitor of rat adipose precursor differentiation in primary cultures with an IC₅₀ value of 3 x 10-12 M. (+)-Cloprostenol isopropyl ester is a more lipid soluble form of cloprostenol.

Isopropyl Cloprostenate is an isopropyl ester derivative of Cloprostenol (C587300); an aryl-oxymethyl analog of prostaglandin F2α.
