Background

A number of 17-phenyl trinor Prostaglandin F_2α derivatives have been approved for the treatment of glaucoma.^1,2,3,4 Of these, the ones wherein the 13,14-double bond has been hydrogenated retain relatively good potency, but show a significantly reduced incidence of local irritant side effects.⁵ Alternatively, it was recently reported that analogs incorporating a 15-deoxy-15,15-difluoro modification also had a favorable ophthalmic activity profile.⁶ Tafluprost is a 2-series, 16-phenoxy analog of PGF_2α with the 15,15-difluoro substitution. Tafluprost free acid is a very potent FP receptor agonist, with a K_i of 0.4 nM.⁶ The ester prodrug forms of tafluprost are also potent ocular hypotensives in monkeys.
