Abstract

The present invention relates to l,5-diaryl-2-alkylpyrrole-3-substituted nitro esters, of formula (I), which are potent and selective COX-2 inhibitors able to release NO in concentrations that make it possible to counteract the side effects due to selective COX-2 inhibition, without giving rise to hypotensive effects. (I). Where the groups R' and R" are: -H, -F, -CI, -Br, -CH3, -CF3, -OCH3, -SCH3, R1 is methyl, ethyl, trifluoromethyl, hydroxymethyl, methoxymethyl and the substituent in position -3 of the pyrrole ring is a chain, where the groups X, Y, Z, W and R2 are: X is a carbonyl or a group -(CHR3)-, Y is an oxygen atom or the group -NR3- and Z is a carbonyl or a group - (CHR3)-, or a [-CH(COOH)-] group, or a group -(NR3)-, W is an aliphatic chain substituted with one or two (-O-NO2) groups, R2 is: -H, -OH, -OCH3, or -NHR3. R3 is: -H, -CH3, -CH2CH3, [-CH2(CH3)2]. R'" is methylsulphonyl or sulphonamido. The purpose of the invention includes: preparation of the compounds of formula (I), the respective pharmaceutical formulations and use thereof for treating acute and chronic pain, for treating inflammatory disorders and for drug treatment of some forms of tumours.
