: This article presents a simplified view of celecoxib as a potential inhibitor in the treatment of inflammatory diseases. The enzyme cyclooxygenase (COX) has, predominantly, two isoforms called cyclooxygenase 1 (COX-1) and cyclooxygenase 2 (COX-2). The former plays a constitutive role that is related to homeostatic effects in renal and platelets, while the latter is mainly responsible for induction of inflammatory effects. Since COX-2 plays an important role in the pathogenesis of inflammatory diseases, it has been signaled as a target for the planning of anti-inflammatory intermediates. Many inhibitors developed and planned for COX-2 inhibition have presented side effects to humans, mainly in the gastrointestinal and/or cardiovascular tract. Therefore, it is necessary to design new potential COX-2 inhibitors, which are relatively safe and without side effects. To this end, of the generation of non-steroidal anti-inflammatory drugs from “coxibs”, celecoxib is the only potent selective COX-2 inhibitor that is still commercially available. Thus, the compound celecoxib became a commercial prototype inhibitor for the development of anti-inflammatory agents for COX-2 enzyme. In this review, we provide highlights where such inhibition should provide a structural basis for the design of promising new non-steroidal anti-inflammatory drugs (NSAIDs) which act as COX-2 inhibitors with lesser side effects on the human body.

Background: Saccular intracranial aneurysms (IAs) are outpouchings of the vessel wall of intracranial arteries. Rupture of IAs results in subarachnoid hemorrhage which is associated with high morbidity and mortality. Surgical interventions, such as clipping and coiling, have associated risks. Currently, there are no proven pharmacological treatments to prevent the growth or rupture of IAs. Infiltration of proinflammatory cytokines in response to increased wall sheer stress is a hallmark of IA. Nonsteroidal anti-inflammatory drugs (NSAIDs) are being investigated as potential therapeutic agents for reduction in growth and/or prevention of IA through inhibition of inflammatory pathways. Summary: This review will discuss the role of NSAIDs in attenuating the inflammation that drives IA progression and rupture. There are two main subtypes of NSAIDs, nonselective COX and selective COX-2 inhibitors, both of which have merit in treating IA. Evidence will be presented which shows that NSAIDs inhibit several key inflammatory mediators involved in IA progression including nuclear factor-κB, tumor necrosis factor-α, and matrix metalloproteinases. In addition, the role of NSAIDs in limiting inflammatory cell adhesion to endothelial cells and attenuating endothelial cell senescence will be discussed. Key Messages: There is an abundance of basic science and preclinical data that support NSAIDs as a promising treatment for IA. Additionally, a combination treatment strategy of low-dose aspirin given concomitantly with a selective COX-2 inhibitor may result in a reduced side effect profile compared to aspirin or selective COX-2 inhibitor use alone. Several large clinical trials are currently planned to further investigate the efficacy of NSAIDs as an effective nonsurgical treatment for IAs.

Background: A convenient approach to modulation of the inflammation has an influence on the production of inflammatory mediators – icosanoids, generated in arachidonic acid (AA) metabolism. The common therapeutic activity of non-steroidal anti-inflammatory drugs (NSAID), such as aspirin, includes inhibition of two crucial enzymes of AA metabolism - cyclooxygenase- 1 and -2 (COX-1/2), with certain risk for gastrointestinal and renal intolerance. Ever since the enrolment of COX-2, particularly overabundance of its main products prostaglandin E2 (PGE2) and thromboxane A2 (TXA2) in numerous pathological processes was recognized, it became a significant therapeutic target. Objective: The aim of this study was to examine the effects of synthesized organo-fluorine compounds on PGE2 and TXA2 production in the inflammation process. Methods: Trifluoromethyl compounds were synthesized from N-benzyl trifluoromethyl aldimine, commercially available 2-methyl or 2-phenyl α-bromo esters (β-lactams trans-1 and trans-2 and trifluoromethyl β-amino ester, respectively) and methyl 2-isocyanoacetate (2-imidazoline trans-4). The reactions proceeded with high geometric selectivity, furnishing the desired products in good yields. The influence of newly synthesized compounds on PGE2 and TXA2 production in human leukemic U937 macrophages on both enzyme activity and gene expression levels was observed. Results: Among the tested trifluoromethyl compounds, methyl trans-1-benzyl-5-(trifluoromethyl)- 4,5-dihydro-1H-imidazole-4-carboxylate (trans-4) can be distinguished as the most powerful antiinflammatory agent, probably due to its trifluoromethyl-imidazoline moiety. Conclusion: Some further structural modifications in tested compounds and particularly in the synthesis of different trifluoromethyl imidazolines could contribute to the development of new COX-2 inhibitors and potent anti-inflammatory agents.

One of the potential cardiotoxic action of anti-inflammatory drugs is the occurrence of heart failure (HF), due to their effects on fluid retention and blood pressure. The risk of hospitalization for HF is roughly doubled for both Coxibs, cyclooxygenase-1 (COX-1) and cyclooxygenase- 2 (COX-2) inhibitors, and all the conventional nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs are also associated with a risk of vascular thrombosis, which for NSAIDs is different in relation to their different ability to inhibit COX-1 and COX-2. The cardiovascular toxicity of these drugs in the direction of HF follow different pathways respect to their related vascular thrombosis toxicity and involves, in particular, the renal prostaglandins, PGE2 and prostacyclin, mostly synthesized by COX-2. In the kidneys the PGs perform a direct vasodilatory action, e.g. by means of non-contrasting angiotensin mechanisms, and for this reason nimesulide effects on renal microcirculation are independent from the prevalence of intrarenal renin angiotensin aldosterone system (RAAS) activity. Conversely, nimesulide reduces sodium tubular urinary flow only in presence of intrarenal RAAS.

AbstractNon steroidal anti-inflammatory drugs are the most widely used medicines for relief of pain. These drugs have some side effects, particularly toxicity in the gastrointestinal tract and kidneys. Various approaches have been used for obtaining safer anti-inflammatory drugs. In this review we have summarized the recent developments in the following areas; (i) mode of action of NSAIDs (ii) Role of COX-1 & COX-2 in inflammation, (iii) Different approaches used to improve gastric tolerance i.e. chemical manipulation, formulation & co-administration, development of non specific (COX-1 & COX-2 inhibitors) and specific (COX-2 inhibitors) inflammation inhibitors, and development of inflammation inhibitors having a mode of action other than COX-1 & COX-2 inhibition. We have also focused on the safety of COX-2 inhibitors and the synthesis of heterocyclic compounds and their role as inflammation inhibitors.

Treatment with non-steroidal anti-inflammatory drugs, either non-selective or selective cyclooxygenase-2 (COX-2) inhibitors, consistently impairs ovulation, indicating the essential role of COX-2/prostaglandins in the ovulatory process. Indomethacin, a potent inhibitor of both COX-1 and COX-2, induced several ovulatory alterations, consisting of a decrease in the number of oocytes effectively ovulated, trapping of oocytes inside the luteinized follicle, as well as abnormal follicle rupture at the basolateral sides, with release of the oocyte and follicular fluid to the interstitium. Yet, the precise role of prostaglandins in ovulation and whether some of the ovulatory defects induced by indomethacin are due to interference with additional components of the ovulatory cascade, beyond prostaglandin synthesis, are not completely understood. We have used gonadotrophin-primed immature rats to analyse whether, compared to indomethacin, selective inhibition of COX-2, with or without concomitant inhibition of COX-1, or selective inhibition of the lipooxygenase (LOX) pathway, induce similar ovulatory alterations. Immature rats (27 days of age) were injected PMSG (10 IU), and 48 h later hCG (10 IU) subcutaneously, and different anti-inflammatory drugs. Animals were killed at 21 h after hCG injection. Rats treated with the selective COX-2 inhibitor NS398 (10 mg/kg body weight, (bw)) showed alterations in follicle rupture as those treated with indomethacin (0.5 mg/rat), albeit affecting a lower number of follicles, irrespective of the concomitant inhibition of COX-1 with the selective inhibitor SC560 (10 mg/kg bw). Rats treated with the LOX inhibitor NDGA (300 mg/kg bw) did not show ovulatory alterations. These data indicate that the characteristic alterations of follicle rupture induced by indomethacin, are also induced by selective COX-2 inhibitors, strengthening the contention that prostaglandins play a crucial role in the spatial targeting of follicle rupture at the apex.

Cox 2 Inhibitors

Non-steroidal anti-inflammatory drugs (NSAIDs) including both traditional non-selective NSAIDs and the selective cyclooxygenase (COX)-2 inhibitors, are widely used for their anti-inflammatory and analgesic effects. NSAIDs are a necessary choice in pain management because of the integrated role of the COX path way in the generation of inflammation and in the biochemical recognition of pain. NSAIDs are the competitive inhibitors of cyclooxygenase (COX), the enzyme which mediates the bioconversion of arachidonic acid to inflammatory prostaglandins (PGs). Their use is associated with the side effects such as gastrointestinal and renal toxicity. They are the most commonly employed first line drugs for all these conditions and many others-like musculoskeletal trauma, minor aches and pains, and dysmenorrhoea. The therapeutic anti-inflammatory action of NSAIDs is produced by the inhibition of COX-2, while the undesired side effects arise from inhibition of COX-1 activity. Thus, it was though those more selective COX-2 inhibitors would have reduced side effects. Based upon a number of selective COX-2 inhibitors (Rofecoxib, Celecoxib etc.) were developed as safer NSAIDs with improved gastric safety profile. Several newer applications like prophylaxis of stroke with aspirin are now common place. Use of these drugs for the prophylaxis of conditions like Alzheimer’s disease and colorectal cancer is being evaluated. Unfortunately, they have several toxicities ranging from minor heartburn to severe gastrointestinal haemorrhage and perforation. Therefore, newer NSAIDs have been introduced in recent years to circumvent this problem. In preliminary studies, these have shown better safety, efficacy, and tolerability but the full spectrum of adverse reactions of these drugs is yet to be fully known. This review can be used for further research as well as clinical purpose. Keywords: Non-steroidal anti-inflammatory drugs (NSAIDs), cyclooxygenase inhibitors, prostaglandins, aspirin.

SummaryEven though non-steroidal anti-inflammatory drugs (NSAIDs) have been widely used for a long time, the search continues for anti-inflammatory drugs with few side-effects. COX-2 inhibitors are currently most debated, because they have less gastrointestinal side effects but have been linked to increased cardiovascular morbidity and mortality, presumably related to thrombotic events. This has brought about the withdrawal of rofecoxib and other COX-2 inhibitors from the market. Although the results of several large studies with prospective, randomized design and meta-analysis of different trials have led to the demise of many popular COX-2 inhibitors, yet the conclusion seems to be rather simplistic. This review presents evidence from basic biology and clinical studies with the expectation that a balanced position, particularly in relation to increase in cardiovascular events, may be elucidated.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly used pain relievers. However, their use often threatens with serious undesirable effects, associated mainly with damage to cardiovascular system (CVS), gastrointestinal tract, kidneys and liver. Contraindications to NSAIDs prescription are clearly regulated, algorithms for their personalized appointment are determined taking into account risk factors for cardiovascular and gastrointestinal adverse events. The severity of NSAIDs side effects is mainly due to the selectivity to cyclooxygenase-2 (COX-2), as well as the physicochemical properties of various drugs. Cardiovascular adverse events differ among various NSAIDs both within commonly used drugs and among COX-2 inhibitors. It is well known that NSAIDs selective for COX-2 are safer in terms of the effect on the gastrointestinal tract than non-selective drugs. A meta-analysis showed that relatively selective COX-2 inhibitors (meloxicam, etodolac) were associated with a comparable risk of developing symptomatic ulcers and ulcers identified by endoscopy, and safety and tolerability profiles of the drugs were similar.All NSAIDs are associated with cardiovascular toxicity, however, different drugs have significant risk differences. The mechanism of NSAIDs cardiovascular adverse effects is associated with an increase of blood pressure, sodium retention, vasoconstriction, platelet activation, and prothrombotic state. It has been shown that the risk of cardiovascular adverse events when taking COX-2 inhibitors (celecoxib, etoricoxib) significantly increases. According to a study of more than 8 million people, it was found that the risk of myocardial infarction was increased in patients taking ketorolac. Further, highest to lowest risk authors list indomethacin, etoricoxib, rofecoxib (not currently used), diclofenac, a fixed combination of diclofenac with misoprostol, piroxicam, ibuprofen, naproxen, celecoxib, meloxicam, nimesulide and ketoprofen. When taking NSAIDs, the risk of heart failure decompensation increases, and it turned out to be the greatest for ketorolac, etoricoxib, and indomethacin. Meloxicam, aceclofenac, ketoprofen almost did not increase heart failure risk. It should be noted that when using the drugs (except for indomethacin and meloxicam), there is a tendency to increase the total cardiovascular and renal risks with increasing doses. Thus, it is obvious that a very careful approach is required when choosing NSAIDs. If there is an increased risk of gastrointestinal complications associated with NSAIDs, selective NSAIDs are preferred, with both coxibs and traditional selective NSAIDs showing the best safety profile in the studies. To minimize cardiovascular side effects specialists should consider the risk level of cardiovascular complications, as well as results of large clinical studies where particular NSAIDs are compared.

Privileged Structures

Rheumatoid arthritis, arthrosis and gout, among other chronic inflammatory diseases are public health problems and represent major therapeutic challenges. Non-steroidal anti-inflammatory drugs (NSAIDs) are the most prescribed clinical treatments, despite their severe side effects and their exclusive action in improving symptoms, without effectively promoting the cure. However, recent advances in the fields of pharmacology, medicinal chemistry, and chemoinformatics have provided valuable information and opportunities for development of new anti-inflammatory drug candidates. For drug design and discovery, thiophene derivatives are privileged structures. Thiophene-based compounds, like the commercial drugs Tinoridine and Tiaprofenic acid, are known for their anti-inflammatory properties. The present review provides an update on the role of thiophene-based derivatives in inflammation. Studies on mechanisms of action, interactions with receptors (especially against cyclooxygenase (COX) and lipoxygenase (LOX)), and structure-activity relationships are also presented and discussed. The results demonstrate the importance of thiophene-based compounds as privileged structures for the design and discovery of novel anti-inflammatory agents. The studies reveal important structural characteristics. The presence of carboxylic acids, esters, amines, and amides, as well as methyl and methoxy groups, has been frequently described, and highlights the importance of these groups for anti-inflammatory activity and biological target recognition, especially for inhibition of COX and LOX enzymes.
