13,14-dihydro Prostaglandin F2α (13,14-dihydro PGF2α) is the analog of PGF2α which has no unsaturation in the lower side chain. It causes luteolysis in hamsters with a potency five times higher than PGF2α. The ED50 value for 13,14-dihydro PGF2α as a luteolytic agent in hamsters is 1.5 µg 100 g.[1]
Cloprostenol is a synthetic derivative of prostaglandin F2α that is used in veterinary medicine as a luteolytic agent for the induction of estrus and in the treatment of reproductive disorders in cattle, swine, and horses. (+)-5-trans Cloprostenol is a minor impurity produced in the synthesis of (+)-cloprostenol. The (+)-5-trans isomer is 20-fold less active than the 5-cis form in terminating pregnancy in the hamster.
(+)-Cloprostenol is a synthetic analog of prostaglandin F2α (PGF2α). It is an FP receptor agonist and a potent luteolytic agent in rats and hamsters. It is 200 times and 100 times more potent than PGF2α in terminating pregnancy in hamsters and rats, respectively, without the side effects associated with PGF2α. Cloprostenol is also used in veterinary medicine as a luteolytic agent for the induction of estrus and the treatment of reproductive disorders in cattle, swine, and horses. (+)-Cloprostenol methyl ester is a more lipid soluble form of cloprostenol, which may be more amenable for certain formulations.
Prostaglandin F2α (PGF2α), acting through the FP receptor, causes smooth muscle contraction and exhibits potent luteolytic activity. 17-trifluoromethylphenyl trinor Prostaglandin F2α (17-trifluoromethylphenyl trinor PGF2α) is an analog of PGF2α that shares the meta-trifluoromethyl group of travoprost with the 17-phenyl trinor modification of latanoprost. It is anticipated to be a potent and selective agonist of the FP receptor, with potential applications in glaucoma and luteolysis. 17-trifluoromethylphenyl trinor PGF2α ethyl amide is a lipophilic analog of 17-trifluoromethylphenyl trinor PGF2α. Ethyl amides of PGs can serve as prodrugs, as they are hydrolyzed in certain tissues to generate the bioactive free acid.
Fluprostenol is an F-series prostaglandin analog which has been approved for many years as a luteolytic in veterinary animals. The isopropyl ester of fluprostenol (travoprost) is an effective ocular hypotensive drug. CAY10532 is a methyl ester analog of fluprostenol.
Prostaglandin F2α (PGF2α), acting through the FP receptor, causes smooth muscle contraction and exhibits potent luteolytic activity. Both 17-phenyl trinor PGF2α and 16-phenoxy tetranor PGF2α are metabolically stable analogs of PGF2α and potent agonists for the FP receptor. 17-phenoxy trinor PGF2α ethyl amide is a lipophilic analog of 17-phenoxy trinor PGF2α . Ethyl amides of PGs serve as prodrugs, as they are hydrolyzed in certain tissues to generate the bioactive free acid.
A number of 17-phenyl trinor prostaglandin F2α (17-phenyl trinor PGF2α) derivatives have been approved for the treatment of glaucoma. Of these, the unsubstituted or meta-substituted aromatic derivatives are the most potent FP receptor agonists. 17-trifluoromethylphenyl trinor PGF2α bears an aromatic ring which is reminiscent of the trifluoromethyl-phenoxy ring of travoprost ((+)-fluprostenol isopropyl ester). As an ocular hypotensive agent, it would be expected that 17-trifluoromethylphenyl trinor PGF2α would act very much like the free acid of travoprost. 17-phenyl trinor PGF2α is a potent luteolytic and abortifacient, with a potency equal to or greater than fluprostenol and cloprostenol.

Methyl esters of PGs serve as prodrugs, as they are efficiently hydrolyzed in certain tissues to generate the bioactive free acid.
