15(R)-17-phenyl trinor Prostaglandin F2alpha isopropyl ester

15(R)-17-phenyl trinor Prostaglandin F2alpha isopropyl ester (15(R)-17-phenyl trinor PGF2alpha isopropyl ester) is the latanoprost-related isomer containing both a double bond at 13,14 and an inverted (beta) hydroxyl group at C-15. Similar to 15(S)-latanoprost, 15(R)-17-phenyl trinor PGF2alpha isopropyl ester is a potential impurity in most commercial preparations of the latanoprost bulk drug product. The IC50 values for the free acid forms of 15(S)-17-phenyl trinor PGF2alpha and 15(R)-17-phenyl trinor PGF2alpha were determined to be 0.71 nM and 30 nM, respectively, in a FP receptor binding assay using the cat iris sphincter muscle. A 3 µg dose of 15(R)-17-phenyl trinor PGF2alpha caused a 1.9 mmHg reduction of IOP in normotensive cynomolgus monkeys.Formal Name: 9alpha,11alpha,15R-trihydroxy-17-phenyl-18,19,20-trinor-prosta-5Z,13E-dien-1-oic acid, isopropyl ester.
