Prostaglandin F2α (PGF2α) drives luteolysis and smooth muscle contraction by activating the FP receptor. Stable, lipophilic analogs of PGF2α are used to modulate luteolysis and treat glaucoma. 16-phenoxy tetranor Prostaglandin F2α isopropyl ester (16-phenoxy tetranor PGF2α isopropyl ester) is a lipophilic analog of 16-phenoxy tetranor PGF2α. Isopropyl esters of PGs serve as prodrugs, as they are efficiently hydrolyzed in certain tissues to generate the bioactive free acid.
15-OH Tafluprost, a prostaglandin F2a (PGF2a) analog, relieves endothelin-1 (ET-1)-induced optic nerve head (ONH) blood flow impairment and ET-1-induced contraction of isolated ciliary artery segments[1].
