[EN] MANUFACTURING PROCESS FOR NO-DONATING COMPOUNDS SUCH AS NO-DONATING DICLOFENAC [FR] PROCEDE DE FABRICATION DE COMPOSES DONNEURS DE NO TELS QUE DU DICLOFENAC DONNEUR DE NO
The present invention relates to a new process for the preparation of NO-donating compounds using a sulfonated intermediate. The invention relates to new intermediates prepared therein suitable for large scale manufacturing of NO-donating compounds. The invention further relates to the use of the new intermediates for the manufacturing of pharmaceutically active NO-donating compounds. The invention further relates to a substantially crystalline form of NO-donating NSAIDs, especially 2-[2-(nitrooxy)ethoxy]ethyl 2-[(2,6-dichlorophenyl)amino]phenyl}acetate, the preparation thereof and to pharmaceutical formulations containing said crystalline form and to the use of said crystalline form in the preparation of a medicament.

Novel polyoxyethyleneesters of ketoprofen (1(a-e)), naproxen (2(a-e)) and diclofenac (3(a-e)) were synthesized and evaluated as potential dermal prodrugs of naproxen, ketoprofen and diclofenac. These esters were obtained by coupling these drugs with polyoxyethylene glycols by a succinic acid spacer. The aqueous solubilities, lipophilicities and hydrolysis rates of esters 1(a-e), 2(a-e) and 3(a-e)
