1,5-diaryl-2-alkylpyrrole-3-substituted nitro esters, of Formula (I)
are provided. Such compounds are potent and selective COX-2 inhibitors which are 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. Formula (I) includes compounds wherein the groups R′ and R″ are: —H, —F, —Cl, —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. Pharmaceutical formulations and methods of making an using such formulations are also provided.
提供了化学式(I)的1,5-二芳基-2-烷基吡咯-3-取代硝酸酯化合物。这些化合物是有效且选择性的COX-2抑制剂,能够释放NO以抵消选择性COX-2抑制引起的副作用,而不会引起低血压作用。化学式(I)包括以下基团:R′和R″为:—H,—F,—Cl,—Br,—CH3,—CF3,—OCH3,—SCH3,R1为甲基,乙基,三氟甲基,羟甲基,甲氧甲基,吡咯环的-3位取代基是链状,其中基团X,Y,Z,W和R2为:X为羰基或—(CHR3)—基团,Y为氧原子或—NR3—基团,Z为羰基或—(CHR3)—基团,或[—CH(COOH)—]基团,或—(NR3)—基团,W为被一个或两个(—O—NO2)基团取代的脂肪链,R2为:—H,—OH,—OCH3或—NHR3。R3为:—H,—CH3,—CH2CH3,[—CH2(CH3)2]。R′″为甲磺酰基或磺酰胺基。还提供了制药配方和使用这种配方的方法。
