17-phenyltrinorProstaglandinF2α (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.
ProstaglandinF2α (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.
