ChongDa Prostaglandin Fine Chemicals Co., Ltd

An F-series prostaglandin (PG) analog in which the C-1 carboxyl group has been modified to an unsubstituted amide. PG N-ethyl amides were recently introduced as alternative PG hypotensive prodrugs.2 Although it has been claimed that PG amides are not converted to the free acids in vivo,2 studies have shown that bovine and human corneal tissue converts the amides of various PGs to the free acids with a conversion efficiency of about 10-20% relative to the hydrolysis of isopropyl esters.3 Bimatoprost amide would be expected to show the typical intraocular effects of latanoprost, but with the much slower hydrolysis pharmacokinetics of the PG N-amides.
