Gasco and coworkers created some metabolically steady selective COX-2 inhibitor NO-donors (CINODs) predicated on a 1,5-diarylimidazole band template [32]. The organic nitrate, nitroxy-substituted alkyloxy groupings had been incorporated using one from the aryl bands being a NO-donor moiety. The sulfonamide derivative having a phenoxyethyl nitrate NO-donor moiety (8) maintained COX-2 selectivity (COX-2 IC50 = 29 M; COX-1 IC50 > 100 M) and exhibited excellent vasodilatory properties in accordance with the mother or father cimicoxib. The matching methanesulfonyl derivative (9) exhibited excellent COX-2 selectivity (COX-2 IC50 = 6.9 M; COX-1 IC50 > 100 M) and vasodilatory properties in accordance with 8. It ought to be noted these book CINODs exhibit reduced COX inhibitory strength in accordance with the lead selective COX-2 inhibitor cimicoxib (COX-2 IC50 = 0.10 M; COX-1 IC50 = 1.9 M). Lately, NitroMed Inc. reported a mixed band of indomethacin derivatives as selective COX-2 inhibitors with NO-donating properties [33]. The indomethacin amide derivative having a natural nitrate NO-donor moiety (10, Amount 3) exhibited effective COX-2 selectivity (COX-2 IC50 = 1.2 M; COX-1 IC50 = 6.0 M) and dental anti-inflammatory activity. The sulfonamide derivative having a nitrooxypropyl NO-donor moiety (11) exhibited excellent COX-2 selectivity in accordance with 10 and was an equipotent inhibitor of COX-2 with dental anti-inflammatory activity.

Appropriately, several different classes of selective COX-2 inhibitors have already been reported and an intensive discussion is normally beyond the range of the review [45]. It ought to be observed that COX-1/COX-2 inhibition and selectivity data is normally extremely variable predicated on the biochemical assay technique utilized. Furthermore, anti-inflammatory/analgesic actions and unwanted effects (GI, renal and cardiovascular) of NSAIDs are extremely dose reliant. These factors donate to the difficulty linked in determining particular COX-1 and COX-2 selectivity ratios for upcoming advancement. 4.

Substance 21 (Body 5) exhibited weakened COX and soyabean LOX inhibitory strength (COX-2 IC50 = 262 M, COX-1 IC50 = 125 M; LOX IC50 = 125.9 M). anti-inflammatory activity data for these agencies never have been reported. 5. Lp-PLA2 Inhibitors The phospholipase A2 (PLA2) enzyme catalyzes the discharge of essential fatty acids such as for example AA, a crucial rate-limiting step, by acting on membrane phospholipids (Figure 2). The released AA gets converted to various pro-inflammatory mediators such as prostaglandins, GSK369796 leukotrienes and platelet-activating factor (PAF) that are known to play a major role in regulating the vascular tone [53]. The PLA2 is classified into three major subtypes: secretory (sPLA2); cytosolic or Ca2+-activated (cPLA2); and inducible or Ca2+-independent (iPLA2). In this regard, Lp-PLA2 also known as platelet-activating factor acetylhydrolase (PAF-AH) is a Ca2+-independent PLA2 that is classified as group VIIA PLA2. Furthermore, recent studies have indicated that Lp-PLA2 is closely involved in the onset and progression of atherosclerosis [53,54,55,56,57]. The enzyme Lp-PLA2 or PAF-AH (analgesic activity, although 29 exhibited a short half life (t1/2 = 1.5 h) in animal models.

Open in a separate window Figure 3 Chemical structures of some representative NO-donor anti-inflammatory agents. Gasco and coworkers developed a series of metabolically stable selective COX-2 inhibitor NO-donors (CINODs) based on a 1,5-diarylimidazole ring template [32]. The organic nitrate, nitroxy-substituted alkyloxy groups were incorporated on one of the aryl rings as a NO-donor moiety. The sulfonamide derivative possessing a phenoxyethyl nitrate NO-donor moiety (8) retained COX-2 selectivity (COX-2 IC50 = 29 M; COX-1 IC50 > 100 M) and exhibited superior vasodilatory properties relative to the parent cimicoxib. The corresponding methanesulfonyl derivative (9) exhibited superior COX-2 selectivity (COX-2 IC50 = 6.9 M; COX-1 IC50 > 100 M) and vasodilatory properties relative to 8. It should be noted that these novel CINODs exhibit decreased COX inhibitory potency relative to the lead selective COX-2 inhibitor cimicoxib (COX-2 IC50 = 0.10 M; COX-1 IC50 = 1.9 M).

However, only rats treated with 10 exhibited increased nitrite and nitrate concentration in plasma indicating its NO-donating property COX-2 selectivity (COX-2 IC50 = 0.12 M; COX-1 IC50 = 0.91 M). In 2009 2009, GlaxoSmithKline (GSK) scientists reported the development of a novel series of trifluoromethylpyrimidine based ring scaffolds (19, COX-2 IC50 = 206 nM; COX-1 IC50 = 62000 nM) as highly potent and selective COX-2 inhibitors [43,44]. Accordingly, several diverse classes of selective COX-2 inhibitors have been reported and a thorough discussion is beyond the scope of this review [45]. It should be noted that COX-1/COX-2 inhibition and selectivity data is highly variable based on the biochemical assay method used. In addition, anti-inflammatory/analgesic activities and side effects (GI, Gpm6a renal and cardiovascular) of NSAIDs are highly dose dependent. These factors contribute to the difficulty associated in determining specific COX-1 and COX-2 selectivity ratios for future development. 4.
