Abstract

A novel hybrid nitric oxide-releasing anti-inflammatory (AI) ester prodrug (NONO-coxib 14) wherein an O(2)-acetoxymethyl 1-(2-carboxypyrrolidin-1-yl)diazen-1-ium-1,2-diolate (O(2)-acetoxymethyl PROLI/NO) NO-donor moiety was covalently coupled to the CH(2)OH group of 3-(4-hydroxymethylphenyl)-4-(4-methylsulfonylphenyl)-5H-furan-2-one (12), was synthesized. The prodrug 14 released a low amount of NO (4.2%) upon incubation with phosphate buffer (PBS) at pH 7.4 which was significantly higher (34.8% of the theoretical maximal release of two molecules of NO/molecule of the parent hybrid ester prodrug) upon incubation in the presence of rat serum. These incubation studies suggest that both NO and the parent compound 12 would be released from the prodrug 14 upon in vivo cleavage by non-specific serum esterases. The prodrug ester 14 is a selective COX-2 inhibitor that exhibited AI activity (ED(50)=72.2mmol/kg po) between that of the reference drugs celecoxib (ED(50)=30.9mumol/kg po) and ibuprofen (ED(50)=327mumol/kg po). The NO donor compound 14 exhibited enhanced inhibition of phenylephrine-induced vasoconstriction of isolated mesenteric arteries compared with that observed under control conditions. These studies indicate hybrid ester AI/NO donor prodrugs (NONO-coxibs) constitutes a plausible drug design concept targeted toward the development of selective COX-2 inhibitory AI drugs that are devoid of adverse cardiovascular effects.
