Hexanoic acid, 6-(nitrooxy)-, (1S,2E)-3-[(1R,2R,3S,5R)-2-[(2Z)-7-(ethylamino)-7-oxo-2-hepten-1-yl]-3,5-dihydroxycyclopentyl]-1-(2-phenylethyl)-2-propen-1-yl ester

15-(6-nitroxyhexanoyl)-17-phenyl trinor Prostaglandin F2α (15-(6-nitroxyhexanoyl)-17-phenyl trinor PGF2α) is a nitric oxide-donating derivative of 17-phenyl trinor PGF2α .1 It increases cGMP levels in rabbit aqueous humor and iris ciliary body when topically administered at a concentration of 0.042%. Topical administration of 15-(6-nitroxylhexanoyl)-17-phenyl trinor PGF2α (0.14%) reduces intraocular hypertension (IOP) in a rabbit model of hypertonic saline-induced transient ocular pressure. It also reduces IOP in a cynomolgus monkey model of laser-induced ocular hypertension when administered topically at a concentration of 0.042%.
