Abstract
Innate inflammation beyond a threshold is a significant problem involved in cardiovascular diseases, cancer, and many other chronic conditions. Cyclooxygenase (COX) enzymes are key inflammatory markers as they catalyze prostaglandins production and are crucial for inflammation processes. While COX-I is constitutively expressed and is generally involved in "housekeeping" roles, the expression of the COX-II isoform is induced by the stimulation of different inflammatory cytokines and also promotes the further generation of pro-inflammatory cytokines and chemokines, which affect the prognosis of various diseases. Hence, COX-II is considered an important therapeutic target for drug development against inflammation-related illnesses. Several selective COX-II inhibitors with safe gastric safety profiles features that do not cause gastrointestinal complications associated with classic anti-inflammatory drugs have been developed. Nevertheless, there is mounting evidence of cardiovascular side effects from COX-II inhibitors that resulted in the withdrawal of market-approved anti-COX-II drugs. This necessitates the development of COX-II inhibitors that not only exhibit inhibit potency but also are free of side effects. Probing the scaffold diversity of known inhibitors is vital to achieving this goal. A systematic review and discussion on the scaffold diversity of COX inhibitors are still limited. To address this gap, herein we present an overview of chemical structures and inhibitory activity of different scaffolds of known COX-II inhibitors. The insights from this article could be helpful in seeding the development of next-generation COX-II inhibitors.

Abstract
Background:
The search for novel antimicrobial agents effective against the emerging resistant
pathogenic microorganisms to the currently used drugs is a substantial need. Herein, a novel series of
compounds bearing a benzothiazolotriazole scaffold was synthesized and evaluated as potential antimicrobial
agents against a panel of gram +ve, gram -ve bacteria, and fungi species.
Methods:
The new compounds were synthesized via hybridization between the benzothiazolotriazole
scaffold and thiadiazole ring or various substituted aromatic moieties using the tethering technique in
drug discovery.
Results:
The in vitro results revealed that these compounds have significant antifungal activity rather than
antibacterial potential due to their high similarity with tricyclazole. Compound 7b bearing bromo-phenyl
moiety was the most potent derivative with an MIC value of 8 μg/mL against Candida albicans and Penicillium
chrysogenum.
Conclusion:
Collectively, benzothiazolotriazole-based derivatives are good antifungal leads and should
be further actively pursued to expand treatment options for systemic and topical fungal infections.

Abstract
Background:
1,2,4-triazoles possess a broad spectrum of biological activities such as analgesic,
antimicrobial, antitubercular, anti-inflammatory and antineoplastic activities. This heterocycle and their derivatives
were included into a wide variety of therapeutically interesting drugs. Hence, it is of great interest to explore
new 1,2,4-triazoles as cytotoxic agents targeting EGFR, B-Raf kinases.
Methods:
The final compounds 9a-b, 10a-b, 11a-b, 12a-b, 13a-b and 14a-f were prepared by refluxing a mixture
of triazole 3a-b and 7a-d with the corresponding benzaldehyde derivatives 8a-d in absolute ethanol to afford
the target final compounds in good yields. The newly synthesized triazole-containing compounds were
assessed according to standard protocols for their in vitro antiproliferative activity against four human cancer
cell lines including human pancreas cancer cell line (Panc-1), pancreatic carcinoma cells (PaCa-2), colon cancer
cells (HT-29) and lung cancer cells (H-460) using the propidium iodide (PI) fluorescence assay. Compounds 9a
and 13a were evaluated against EGFR, B-Raf and Tubulin anticancer targets.
Results:
Compounds 9a, 9b, 10a, 11a, 12a, 13a and 13b showed remarkable antiproliferative activity against
the tested cell lines with IC50 range of 1.3-5.9µM. Compounds 9a and 13a with the least IC50 values in the anticancer
screening assay were tested against three known anticancer targets including EGFR, B-Raf kinase and
Tubulin. The results revealed that compound 13a showed the highest potency against B-Raf and EGFR kinases
with IC50 = 0.7 and 1.9 µM, respectively.
Conclusion:
1,2,4-triazoles reported herein are potent EGFR, B-Raf inhibitors. These lead compounds will be
subjected to more detailed mechanistic studies.

Abstract
Inflammation is a natural process that is connected to various conditions and disorders such as arthritis, psoriasis, cancer, infections, asthma, etc. Based on the fact that cyclooxygenase isoenzymes (COX-1, COX-2) are responsible for the production of prostaglandins that play an important role in inflammation, traditional treatment approaches include administration of non-steroidal anti-inflammatory drugs (NSAIDs), which act as selective or non-selective COX inhibitors. Almost all of them present a number of unwanted, often serious, side effects as a consequence of interference with the arachidonic acid cascade. In search for new drugs to avoid side effects, while maintaining high potency over inflammation, scientists turned their interest to the synthesis of dual COX/LOX inhibitors, which could provide numerous therapeutic advantages in terms of anti-inflammatory activity, improved gastric protection and safer cardiovascular profile compared to conventional NSAIDs. Τhiazole and thiazolidinone moieties can be found in numerous biologically active compounds of natural origin, as well as synthetic molecules that possess a wide range of pharmacological activities. This review focuses on the biological activity of several thiazole and thiazolidinone derivatives as COX-1/COX-2 and LOX inhibitors.

Abstract
Over the last few decades, a growing body of studies addressed the anticancer activity of NSAIDs, particularly selective COX-2 inhibitors. However, their exact molecular mechanism is still unclear and is not fully investigated. In this regard, a novel series of compounds bearing a COXs privilege scaffold, diphenyl thiazole, was synthesized and evaluated for their anticancer activity against a panel of cancer cell lines. The most active compounds 10b, 14a,b, 16a, 17a,b and 18b were evaluated in vitro for COX-1/COX-2 inhibitory activity. These compounds were suggested to exert their anticancer activity through a multi-target mechanism based on their structural features. Thus, compounds 10b and 17b with the least IC50 values in MTT assay were tested against three known anticancer targets; EGFR, BRAF and tubulin. Compounds 10b and 17b showed remarkable activity against EGFR with IC50 values of 0.4 and 0.2μM, respectively and good activity against BRAF with IC50 values of 1.3 and 1.7μM, respectively. In contrast, they showed weak activity in tubulin polymerization assay. The in vivo anti-inflammatory potential was assessed and interestingly, compound 17b was the most potent compound. Together, this study offers some important insights into the correlation between COXs inhibition and cancer treatment. Additionally, the results demonstrated the promising activity of these compounds with a multi-target mechanism as good candidates for further development into potential anticancer agents.

Abstract
The inhibition of gastric cyclooxygenase 1 (COX-1) enzyme was believed to be the major cause of non-steroidal anti-inflammatory drugs (NSAIDs)-induced gastric ulcer. Recent studies disproved this belief and showed that the gastric tissues vulnerability is not solely connected to COX-1 inhibition. This work aimed at exploring and rationalizing the differential analgesic and anti-inflammatory activities of novel selective COX-1 inhibitors with improved gastric profile. Two novel series of 4,5-diarylthiazole and diarylimidazole were designed, synthesized in analogy to selective COX-1 inhibitors (mofezolac and FR122047) which lack gastric damaging effects. The new compounds were evaluated in vitro for their COXs inhibitory activity and in vivo for their anti-inflammatory and analgesic potentials. Four compounds; diphenylthiazole glycine derivatives (15a, 15b) and diphenylimidazolo acetic acid derivatives (19a, 19b), which possess carboxylic acid group exhibited significant activity and selectivity against COX-1 over COX-2. Of these compounds, (4,5-bis(4-methoxyphenyl)thiazol-2-yl)glycine 15b was the most potent compound against COX-1 with an inhibitory half maximal concentration (IC50) of 0.32μM and a selectivity index (COX-2 IC50/COX-1 IC50) of 28.84. Furthermore, an ulcerogenicity study was performed where the tested compounds demonstrated a significant gastric tolerance. Interestingly, the most selective COX-1 inhibitor showed higher analgesic activity in vivo as expected compared to their moderate anti-inflammatory activity. This study underscores the need for further design and development of novel analgesic agents with low tendency to cause gastric damage based on improving their COX-1 affinity and selectivity profile.

Abstract
A series of novel quinoline-2-carboxamides 15-28 was synthesized and evaluated in vitro as dual COXs/LOX inhibitors. Compounds 19 and 27 exhibited the highest potency and selectivity for COX-2 inhibitory activity (IC50 = 1.21 and 1.13 μM, respectively; selectivity index (COX-1/COX-2) = 6.52 and 7.61, respectively) in comparison to the reference drug celecoxib (COX-2 IC50 = 0.88 μM; selectivity index (COX-1/COX-2) = 8.31). The anti-inflammatory activity of the newly synthesized compounds was further assessed in vivo using carrageenan induced paw edema assay. Interestingly, the in vitro results of COXs inhibitory assay were consistent with that of the in vivo assay where compounds 19 and 27 showed the highest anti-inflammatory activity with edema inhibition percentages of 59.38% and 65.03%, respectively compared to celecoxib (71.21%) after 5 h. Moreover, it was found that compounds 19 and 27 have a superior gastric safety profile comparable to indomethacin. The molecular docking study of compounds 19 and 27 into COX-2 active site suggested that these hits assumed binding pattern and interactions similar to that of bromocelecoxib (S-58) as a cocrystallized ligand explaining their remarkable COX-2 inhibitory activity and selectivity. Taken together, these results indicated that these derivatives are good leads for subsequent development into potential anti-inflammatory agents with least gastric damage.

Design, Synthesis, and Biological Evaluation of Some Novel Pyrrolizine Derivatives as COX Inhibitors with Anti-Inflammatory/Analgesic Activities and Low Ulcerogenic Liability. Molecules 2016; 21:molecules21020201. [PMID: 26867188 PMCID: PMC6273963 DOI: 10.3390/molecules21020201] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2015] [Revised: 01/29/2016] [Accepted: 02/01/2016] [Indexed: 11/18/2022] Open
Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are the most commonly prescribed anti-inflammatory and pain relief medications. However, their use is associated with many drawbacks, including mainly serious gastric and renal complications. In an attempt to circumvent these risks, a set of N-(4-bromophenyl)-7-cyano-6-substituted-H-pyrrolizine-5-carboxamide derivatives were designed, synthesized and evaluated as dual COX/5-LOX inhibitors. The structural elucidation, in vivo anti-inflammatory and analgesic activities using a carrageenan-induced rat paw edema model and hot plate assay, were performed, respectively. From the results obtained, it was found that the newly synthesized pyrrolizines exhibited IC50 values in the range of 2.45–5.69 µM and 0.85–3.44 µM for COX-1 and COX-2, respectively. Interestingly, compounds 12, 13, 16 and 17 showed higher anti-inflammatory and analgesic activities compared to ibuprofen. Among these derivatives, compounds 16 and 19 displayed better safety profile than ibuprofen in acute ulcerogenicity and histopathological studies. Furthermore, the docking studies revealed that compound 17 fits nicely into COX-1 and COX-2 binding sites with the highest binding affinity, while compound 16 exerted the highest binding affinity for 5-LOX. In light of these findings, these novel pyrrolizine-5-carboxamide derivatives represent a promising scaffold for further development into potential dual COX/5-LOX inhibitors with safer gastric profile.
