17-phenyltrinorProstaglandin F2α (17-phenyltrinor PGF2α) is a metabolically stable analog of PGF2α and is a potent agonist for the FP receptor, binding with a relative potency of 756% compared to that of PGF2α. The ethyl amide of 17-phenyltrinor PGF2α bimatoprost has been approved for use as an ocular hypotensive drug. 17-phenyltrinor PGF2α methylamide is an analog of bimatoprost. Its biological and toxicological properties have not been evaluated.
Prostaglandin F2α (PGF2α) activates the FP receptor, promoting smooth muscle contraction and luteolysis. 17-phenyltrinor PGF2α binds the FP receptor on ovine luteal cells with a relative potency of 756% compared to that of PGF2α. It is produced in vivo by the hydrolysis of 17-phenyltrinor PGF2α ethyl amide. 17-phenyltrinor PGF2α ethyl amide is used to reduce intraocular pressure related to glaucoma. 17-phenyltrinor PGF2α cyclopropyl methylamide is a lipophilic analog of 17-phenyltrinor PGF2α. Amides of PGs may serve as prodrugs, as they are hydrolyzed in certain tissues to generate the bioactive free acid.
