Latanoprost ethyl amide-d4 (Lat-NEt-d4) contains four deuterium atoms at the 3, 3′, 4, and 4′ positions. It is intended for use as an internal standard for the quantification of Lat-NEt by GC- or LC-mass spectrometry. Lat-NEt is an F-series prostaglandin (PG) analog in which the C-1 carboxyl group has been modified to an N-ethyl amide. PG esters have been shown to have ocular hypotensive activity.{8837} PG N-ethyl amides were recently introduced as alternative PG ocular hypotensive prodrugs.{8941} Although it has been claimed that PG ethyl amides are not converted to the free acids in vivo,{8941} studies in our laboratories have shown that bovine and human corneal tissue converts the N-ethyl amides of various PGs to the free acids with a conversion rate of about 2.5 µg/g corneal tissue/hr.{9311} Lat-NEt would be expected to show the typical intraocular effects of Lat free acid, but with the much slower hydrolysis pharmacokinetics of the PG N-amides.
