[Synthesis and pharmacologic study of new esters of naproxen with derivatives of N-oxyethylpiperazine].
The preparation of naproxen esters with N,N'-dioxyethylpiperazine and derivatives of N-oxyethylpiperazine with various substituents on the nitrogen is described. Study of analgesic-antiinflammatory properties in comparison with a reference compounds has shown that in most of the new compounds analgesic activity (phenylquinone) is preserved whereas antiinflammatory activity (carrageenin) is generally reduced. The diester with N,N'-dioxyethylpiperazine (MG 28136) proved most interesting, showing clear pharmacological activity and very low toxicity.
