Abstract
A Lewis acid-promoted electrophilic thiocyanation/cyclization of ortho-alkynylanilines for the synthesis of indole derivatives has been developed. The reaction utilizes Me3SiBr as the Lewis acid and N-thiocyanatosuccinimide as the thiocyanation reagent. A series of 2-aryl-3-thiocyanato indoles were prepared in moderate to high yields under mild conditions without metals and oxidants. It provides an efficient protocol for the construction of the indole skeleton and C-SCN and C-N bonds in one step as well.

Tetraclinis articulata (Vahl) Mast. essential oil as a promising source of bioactive compounds with antimicrobial, antioxidant, anti-inflammatory and dermatoprotective properties: In vitro and in silico evidence. Heliyon 2024; 10:e23084. [PMID: 38169772 PMCID: PMC10758745 DOI: 10.1016/j.heliyon.2023.e23084] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 11/19/2023] [Accepted: 11/27/2023] [Indexed: 01/05/2024] Open
Abstract
Tetraclinis articulata is a known traditional medicinal plant used to manage various ailments, such as diabetes, rheumatism and infectious diseases. This study aims to determine the chemical constituents of T. articulata essential oil (EO) and to evaluate its in vitro antibacterial, anti-candidal, antioxidant, anti-inflammatory and dermatoprotective properties. In addition, a computational docking approach was used to predict the potential antioxidant, antibacterial, antifungal, anti-inflammatory, and cytotoxic properties of the identified compounds. The volatile oil obtained by hydrodistillation was characterized using gas chromatography-mass spectrometry (GC-MS). The antioxidant activity of T. articulata EO was investigated using three complementary assays: DPPH, ABTS and FRAP. Lipoxygenase (5-LOX) and tyrosinase enzymes were used to assess the anti-inflammatory and dermatoprotective effects of this oil. Moreover, disc-diffusion technique, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) assays were employed for the antimicrobial screening. The GC-MS analysis revealed that bornyl acetate (41.80 %), α-pinene (17.97 %) and camphor (15.97 %) are the major components of the studied EO. Moreover, T. articulata EO has exhibited promising antioxidant effect on FRAP, DPPH, and ABTS experiments. It also significantly inhibited 5-LOX (IC50 = 67.82 ± 0.03 μg/mL) and tyrosinase (IC50 = 211.93 ± 0.02 μg/mL). The results of MIC and MBC assays indicated that T. articulata EO is able to inhibit the growth of all tested bacteria (Gram + and Gram -) and Candida species. The ratio of tolerance level indicated that the tested oil was bactericidal against the Gram + bacteria and Candida species, whereas it has a bacteriostatic behavior against the Gram- bacteria. In light of these findings, T. articulata EO may be suggested as a potential pharmaceutical agent to prevent inflammation and skin problems and may serve as a natural antimicrobial and antioxidant alternative for sustainable application in food products.

Abstract
Tamarindus indica L., is widely used tree in ayurvedic medicine. Here, we aimed to understand the presence of important constituents in seeds and peel of Tamarind fruits and their biological activities. Hence, seeds and peel of Tamarind fruits are used for further extraction process by soxhlet method (chloroform and ethyl acetate solvents). Results suggest that the ethyl acetate extract (seeds) consists of terpenoids (72.29 ± 0.513 mg/g), phenolic content (68.67 ± 2.11 mg/g) and flavonoids (26.36 ± 2.03 mg/g) whereas chloroform extract (seeds) has terpenoids (42.29 ± 0.98 mg/g). Similarly, chloroform extract (peel) has terpenoids (25.96 ± 3.20 mg/g) and flavonoids (46.36 ± 2.03 mg/g) whereas ethyl acetate extract (peel) has terpenoids (62.93 ± 0.987 mg/g). Furthermore, anti-inflammation activity results revealed that the chloroform extract of peel was found to be more effective with IC50 of 226.14 µg/ml by protein denaturation analysis and with IC50 of 245.5 µg/ml on lipoxygenase inhibition activity. Chloroform extract (peel and seeds) shown better antioxidant activity using DPPH than ethyl acetate extract (peel and seeds). Ethyl acetate extract of seeds showed impressive potency by inhibiting the growth of fungus, Candida albicans. Additionally, ethyl acetate extract of seeds showed impressive potency inhibiting the growth of Escherichia coli than Bacillus cereus. GC-MS analysis shown the existence of diverse set of phytochemicals in each extract. Overall, comparative studies highlight the effectiveness of seeds extracts than peel extracts. Moreover, GC-MS results suggest that the seeds and peel extracts (chloroform and ethyl acetate) contains a wide range of compounds (including flavonoids, isovanillic acid, fatty acids and phenolic compounds) which can be utilized for therapeutic purpose.

Abstract
The present study investigated the phytochemical content of Hibiscus panduriformis, Alternanthera pungens, and Wissadula rostrata and assessed their radical scavenging and anti-inflammatory properties. n-Hexane, dichloromethane (DCM), ethyl acetate, and methanol extracts were prepared from the powdered plant parts. The phytochemical analysis was performed using qualitative high-performance thin-layer chromatography, and polyphenols were quantified using well-established methods. The anti-inflammatory effect was by lipoxygenase inhibition, while the antiradical impact was evaluated through DPPH and ABTS radicals. Steroids, triterpenoids, flavonoids, and tannins were identified in the three plants. The highest phenolic content (95.67 ± 2.19 mg gallic acid equivalent/g) was obtained in the methanolic extract of W. rostrata, while the lowest was measured in H. panduriformis. H. panduriformis was found to be highly rich in flavonoids (61.22 ± 0.09 mg rutin equivalent/g), condensed tannins (62.53 ± 0.03 mg catechin equivalent/g), and hydrolyzable tannins (125.1 ± 1.02 mg tannic acid equivalent/g). The methanolic extract of H. panduriformis displayed the greatest antilipoxygenase activity with an IC50 value of 8.78 ± 1.05 μg/mL. It should be noted that although a moderate to low effect was observed, the extracts were more likely to scavenge DPPH (IC50 values ranged from 0.106 ± 0.010 to 1 mg/mL) than ABTS radicals. There was a strong to moderate correlation between the antilipoxygenase and DPPH radical scavenging effects of the methanolic extracts and total phenolic content (antilipoxygenase, r = 0.7175; DPPH, r = 0.9376). Furthermore, it is worth noting that this is the first report investigating the phytochemical analysis and in vitro biological properties of Hibiscus panduriformis. The results highlighted the richness of this plant in polyphenols and demonstrated its high and moderate effects on lipoxygenase and DPPH radicals, respectively. To this intent, further in vivo and in vitro studies on this plant, along with exhaustive phytochemical analysis, are needed.

Abstract
Aegle marmelos (L.) Correa is an Indian medicinal plant known for its vast therapeutic activities. In Ayurveda, the plant is known to balance "vata," "pitta," and "kapha" dosh. Recent studies suggest anti-inflammatory, anti-microbial, and anti-diabetic potential but lack in defining the dosage over the therapeutic activities. This study aims to determine the chemical profile of Aegle marmelos fruit extract; identification, enrichment, and characterization of the principal active component(s) having anti-inflammatory and anti-diabetic potential. Targeted enrichment of total coumarins, focusing on marmelosin, marmesin, aegeline, psoralen, scopoletin, and umbelliferone, was done from Aegle marmelos fruit pulp, and characterized using advanced high-throughput techniques. In vitro and in silico anti-diabetic and anti-inflammatory activities were assessed to confirm their efficacy and affinity as anti-diabetic and anti-inflammatory agents. The target compounds were also analysed for toxicity by in silico ADMET study and in vitro MTT assay on THP-1 and A549 cell lines. The coumarins enrichment process designed, was found specific for coumarins isolation as it resulted into 48.61% of total coumarins enrichment, which includes 31.2% marmelosin, 8.9% marmesin, 4% psoralen, 2% scopoletin, 1.7% umbelliferone, and 0.72% aegeline. The quantification with HPTLC and qNMR was found to be correlated with the HPLC assay results. The present study validates the potential use of Aegle marmelos as an anti-inflammatory and anti-diabetic agent. Coumarins enriched from the plant fruit have good therapeutic activity and can be used for Phytopharmaceutical ingredient development. The study is novel, in which coumarins were enriched and characterized by a simple and sophisticated methodology.

Nervonic acid improves liver inflammation in a mouse model of Parkinson's disease by inhibiting proinflammatory signaling pathways and regulating metabolic pathways. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 117:154911. [PMID: 37276724 DOI: 10.1016/j.phymed.2023.154911] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Revised: 05/25/2023] [Accepted: 05/29/2023] [Indexed: 06/07/2023]
Abstract
BACKGROUND Nervonic acid (NA) - a type of bioactive fatty acid that is found in natural sources - can inhibit inflammatory reactions and regulate immune system balance. Therefore, the use of NA for the treatment of neurodegenerative diseases has received considerable attention. Our previous study found that NA inhibited inflammatory responses in the brain of Parkinson's disease (PD) mouse models. In addition to the brain, PD is also associated with visceral organ dysfunction, especially impaired liver function. Thus, studying the role of NA in PD-mediated inflammation of the liver is particularly important. METHODS A combined transcriptome and metabolomic approach was utilized to investigate the anti-inflammatory effects of NA on the liver of PD mice. Inflammatory signaling molecules and metabolic pathway-related genes were examined in the liver using real-time PCR and western blotting. RESULTS Liver transcriptome analysis revealed that NA exerted anti-inflammatory effects by controlling several pro-inflammatory signaling pathways, such as the down-regulation of the tumor necrosis factor and nuclear factor kappa B signaling pathways, both of which were essential in the development of inflammatory disease. In addition, liver metabolomic results revealed that metabolites related to steroid hormone biosynthesis, arachidonic acid metabolism, and linoleic acid metabolism were up-regulated and those related to valine, leucine, and isoleucine degradation pathways were down-regulated in NA treatment groups compared with the PD model. The integration of metabolomic and transcriptomic results showed NA significantly exerted its anti-inflammatory function by regulating the transcription and metabolic pathways of multiple genes. Particularly, linoleic acid metabolism, arachidonic acid metabolism, and steroid hormone biosynthesis were the crucial pathways of the anti-inflammatory action of NA. Key genes in these metabolic pathways and key molecules in inflammatory signaling pathways were also verified, which were consistent with transcriptomic results. CONCLUSION These findings provide novel insights into the liver protective effects of NA against PD mice. This study also showed that NA could be a useful dietary element for improving and treating PD-induced liver inflammation.

Abstract
This review article is the second in a series aimed at providing an in-depth overview of Lavandula x intermedia (lavandin). In part I, the biology and chemistry of lavandin were addressed. In part II, the focus is on the functional properties of lavandin and its applications in industry and daily life. While reviewing the biological properties, only original research articles employing lavandin were considered. Lavandin essential oil has been found to have antioxidant and biocidal activity (antimicrobial, nematicidal, antiprotozoal, insecticidal, and allelopathic), as well as other potential therapeutic effects such as anxiolytic, neuroprotective, improving sleep quality, antithrombotic, anti-inflammatory, and analgesic. Other lavandin preparations have been investigated to a much lesser extent. The research is either limited or inconsistent across all studies, and further evidence is needed to support these properties. Unlike its parent species—Lavandula angustifolia (LA)—lavandin essential oil is not officially recognized as a medicinal raw material in European Pharmacopeia. However, whenever compared to LA in shared studies, it has shown similar effects (or even more pronounced in the case of biocidal activities). This suggests that lavandin has similar potential for use in medicine.

Abstract
Introduction: Psidium cattleianum Sabine is a Brazilian native shrub cultivated for its edible fruit araçá (strawberry guava). P. cattleianum is recognized for health and food applications, although the essential oils (EOs) from the Egyptian inhabitant are not fully explored. The current study investigated the anti-inflammatory and cytotoxic activities of EOs from P. cattleianum leaves and flowers. Materials and methods: The EOs were obtained by three different methods viz; the conventional hydro-distillation, microwave assisted hydro-distillation, and supercritical fluid extraction, while their analysis was accomplished using GC/MS. The derived EOs were screened for their anti-inflammatory activity in the 5-lipoxygenase, COX-1, and COX-2 enzyme based assays, while the anticancer potential was deduced from MTT cytotoxic assay, cell cycle, and western blotting analysis. Results and discussion: Among other methods, supercritical fluid extraction offered the highest EO yield, 0.62% (leaves) and 1.4% (flowers). GC/MS identified β-caryophyllene and α-humulene in both organs with high but variable percentages. The leaves demonstrated strong activity in inhibiting the 5-lipoxygenase enzyme (IC50 2.38), while the flowers, in inhibiting COX-2 (IC50 2.575). Moreover, the leaves showed potent, selective cytotoxicity to MCF-7 cells (IC50 5.32) via apoptosis by modulating the p53/Bax/Bcl2 axis. The deduced activities are possible due to the synergism between the volatile components that endorses P. cattleianum leaves' EOs in the management of breast cancer and inflammatory disorders.

Abstract
Repurposing existing drugs, as well as natural and artificial sweeteners for novel therapeutic indications could speed up the drug discovery process since numerous associated risks and costs for drug development can be surpassed. In this study, natural and artificial sweeteners have been evaluated by in silico and experimental studies for their potency to inhibit lipoxygenase enzyme, an enzyme participating in the inflammation pathway. A variety of different methods pinpointed that aspartame inhibits the lipoxygenase isoform 1 (LOX-1). In particular, "LOX-aspartame" complex, that was predicted by docking studies, was further evaluated by Molecular Dynamics (MD) simulations in order to assess the stability of the complex. The binding energy of the complex has been calculated after MD simulations using Molecular Mechanics/Generalized Born Surface Area (MM/GBSA) method. Furthermore, Quantum Mechanics/Molecular Mechanics (QM/MM) calculations have been applied for geometry optimization of the "enzyme-ligand" complex. After having fully characterized the "LOX-aspartame" complex in silico, followed in vitro biological assays confirmed that aspartame inhibits LOX-1 (IC50=50 ± 3.0 μΜ) and blocks its biological response. The atomic details of aspartame's interaction profile with LOX-1 were revealed through Saturation Transfer Difference (STD) NMR (Nuclear Magnetic Resonance). Finally, aspartame was also tested with Molecular Docking and Molecular Dynamics studies for its potent binding to a number of different LOX isoforms of many organisms, including human. The in silico methods indicated that aspartame could serve as a novel starting point for drug design against LOX enzyme. Communicated by Ramaswamy H. Sarma.

Abstract
Porcine placenta extract (PPE) contains many water-soluble macromolecular compounds, such as proteins and growth factors, which have limited transportation through the skin. This study aimed to assess the effect of porcine-placenta-extract (PPE)-loaded nano-transdermal systems for skin repair and hair growth promotion. The potentials of the nanoformulation for cytotoxicity, cell proliferation, intracellular reactive oxygen species (ROS) reduction, lipoxygenase inhibition, intracellular inflammatory cytokine reduction, and cell aggregation were evaluated. PPE-entrapped niosome nanovesicles were produced by thin-film hydration and probe-sonication methods, followed by incorporation in a skin serum formulation. The physicochemical properties of the formulation were examined, and the efficacy of the serum formulation was elucidated in humans. The results showed that PPE had no toxicity and was able to induce cell growth and cell aggregation. In addition, PPE significantly decreased intracellular ROS, inhibited lipoxygenase activity, and reduced the production of intracellular tumor necrosis factor-α. In the in vivo human study, the PPE nanovesicles-loaded serum could improve skin properties by increasing skin hydration. Moreover, it was capable of promoting hair growth by increasing hair elongation and melanin index after application for one month. Consequently, the PPE nanovesicles-loaded serum was effective for skin anti-aging and hair rejuvenation.

Molecules 2022; 27:molecules27123692.

Abstract
Y. schidigera contains a number of unusual polyphenols, derivatives of resveratrol and naringenin, called spiro-flavostilbenoids, which have potent in vitro anti-inflammatory, antioxidant, and moderate cholinesterase inhibitory activities. To date, these compounds have not been tested in vivo for the treatment of neurodegenerative diseases. The aim of the present study was to evaluate the effects of both single spiro-flavostilbenoids (yuccaol B and gloriosaol A) and phenolic fractions derived from Y. schidigera bark on scopolamine-induced anxiety and memory process deterioration using a Danio rerio model. Detailed phytochemical analysis of the studied fractions was carried out using different chromatographic techniques and Nuclear Magnetic Resonance (NMR). The novel tank diving test was used as a method to measure zebrafish anxiety, whereas spatial working memory function was assessed in Y-maze. In addition, acetylcholinesterase/butyrylcholinesterase (AChE/BChE) and 15-lipooxygenase (15-LOX) inhibition tests were performed in vitro. All pure compounds and fractions under study exerted anxiolytic and procognitive action. Moreover, strong anti-oxidant capacity was observed, whereas weak inhibition towards cholinesterases was found. Thus, we may conclude that the observed behavioral effects are complex and result rather from inhibition of oxidative stress processes and influence on cholinergic muscarinic receptors (both 15-LOX and scopolamine assays) than effects on cholinesterases. Y. schidigera is a source of substances with desirable properties in the prevention and treatment of neurodegenerative diseases.

Abstract
Despite the greatest achievement in the development of anti-inflammatory agents in the last two decades, the current clinical drugs suffer from a variety of complications in community settings and hospital. There is still an urgent need to design novel molecules with better safety profile and with different molecular targets from those in current clinical use. The aim of this research was to discover a series of benzothiazole-based thiazolidinones with lipoxygenase (LOX) inhibitory activity as a mechanism of anti-inflammatory action. Carrageenan-induced mouse foot paw oedema assay was carried out to determine the anti-inflammatory activity, while LOX inhibition was examined through the conversion of sodium linoleate to 13-hydroperoxylinoleic acid. Molecular docking studies were performed using AutoDock 4.2 software. The anti-inflammatory activity of the title compounds was determined in a range of 18.4%-69.57%, where compound #3 was found to be the most potent (69.57%) and also to be more active than the reference drug indomethacin (47%). Moreover, compound #3 showed the highest LOX inhibitory activity with IC50 of 13 μM being less potent to that of the reference NDGA (IC50 = 1.3 μM). Compound #3 has been identified as lead compound for further modification in an attempt to improve anti-inflammatory and LOX inhibitory activities.

Abstract
Background and aim Kaempferia galanga, also known as aromatic Ginger (kencur) in Indonesia, has been widely explored and shows potential as an anti-inflammatory agent. However, there has been limited research to show a possible mechanism by which aromatic ginger inhibits lipoxygenase (LOX). Therefore, this study aims to determine the anti-inflammatory activity of aromatic ginger by comparing extract, fractions, and ethyl-p-methoxycinnamate (EPMC) isolate, as well as possible LOX inhibition activity, by reducing the production of leukotriene B4 (LTB4). Experimental procedure Two animal models were used, namely, the carrageenan-induced granuloma air pouch model and the pleurisy model. The test substance was administered 1 h before carrageenan induction, which was performed orally for each animal model. The number of leukocytes and the malondialdehyde (MDA) levels, leukotriene B4 (LTB4) levels, and histology were observed. GC-MS and LC-MS were used for analysis of the chemical compounds in the test samples. Results and conclusion The results of GC-MS analysis showed that aromatic ginger rhizome extract and fractions were dominated by ethyl-trans-p-methoxycinnamate, with the highest level found in the extract. K. galanga showed significant anti-inflammatory activity compared to the control (p < 0.01) in both the granuloma air pouch and pleurisy models. The results of examining the LTB4 concentration showed comparable activity between K. galanga extract, fractions and EMPC isolate, these results were not better than those of zileuton. Overall, this study shows that aromatic ginger extract, fractions and EPMC isolate have anti-inflammatory properties and have the potential to inhibit LOX, thereby reducing LTB4 levels. Comparison of extract, fraction and isolate of Kamperia galanga anti-inflammation activity. Anti-inflammatory activity of Kaempferia galanga in pleurisy model. Extract, fraction and isolate of Kamperia galanga as LOX inhibitor.

Abstract
Searching small molecules as an auspicious approach to develop new anti-inflammatory drugs is a challenge for the researchers especially by modifying active pharmacophoric groups in the targeted molecules. In the current work, a series of new S-alkyl/aralky derivatives (8a-h; 9a-h) of 2-(4-ethyl/phenyl-5-(1-phenylcarbamoylpiperidine)-4H-1,2,4-triazol-3-ylthio)ether were synthesized and assessed for their inhibitory action against the 15-lipoxygenase from soybean (15-sLOX). The basic precursor ethyl piperidine-4-carboxylate (a) was consecutively changed into phenylcarbamoyl derivative (1), hydrazide (2), semicarbazides (3/4) and N-ethyl/phenyl-5-(1-phenylcarbamoylpiperidine)-1,2,4-triazoles (5/6), which further in association with electrophiles (7a-h) promoted to the final products (8a-h; 9a-h). The synthesized derivatives were characterized by FT-IR, 1H-, 13C NMR spectroscopy, EI-MS, and HR-EI-MS spectrometry. Amongst these, 8a, 8c, and 9c, expressed potent inhibitory profiles against the 15-sLOX enzyme with IC50 values of 12.52 ± 0.35 to 35.64 ± 0.29 µM, followed by the compounds 9b, 9g, 9d, 9a, 8b, 8e, 8d, 8g, 8h, 8f and 9h with IC50 values in the range of 43.78 ± 0.43 to 108.65 ± 0.38 µM. All compounds exhibited variable cellular viability levels by MTT assay. Flow cytometric data demonstrated that 8f, 8g, 8h have maximal lymphocyte cellular viability and all compounds affected cells in the late apoptosis phase. In silico ADMET studies supported the drug-likeness of most of the molecules. These studies were supported by molecular docking against 15-sLOX, human 5-LOX (5-hLOX) and human 15-LOX (5-hLOX); that inhibitors of 15-sLOX docked-in the active pocket of either 5-hLOX or 15-hLOX and docking score remained constant for all three enzymes within a narrow range (-6.8 to -9.7) as did it for standard quercetin (-8.4 to -9.0). The most dominant bonding interactions were π-π, π-anion, and π-alkyl type along with the hydrogen bonding. The data collected altogether demonstrates the better possibility of some of these compounds as good LOX inhibitors in search for 'lead' as anti-inflammatory agents in the process of drug discovery and development.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, known as coronavirus disease 2019 (COVID-19) causes cytokine release syndrome (CRS), leading to acute respiratory distress syndrome (ARDS), acute kidney and cardiac injury, liver dysfunction, and multiorgan failure. Although several studies have discussed the role of 5-lipoxygenase (5-LOX) in viral infections, such as influenzae and SARS, it remains unexplored in the pathophysiology of COVID-19. 5-LOX acts on free arachidonic acid (AA) to form proinflammatory leukotrienes (LTs). Of note, numerous cells involved with COVID-19 (e.g., inflammatory and smooth muscle cells, platelets, and vascular endothelium) widely express leukotriene receptors. Moreover, 5-LOX metabolites induce the release of cytokines (e.g., tumour necrosis factor-α [TNF-α], interleukin-1α [IL-1α], and interleukin-1β [IL-1β]) and express tissue factor on cell membranes and activate plasmin. Since macrophages, monocytes, neutrophils, and eosinophils can express lipoxygenases, activation of 5-LOX and the subsequent release of LTs may contribute to the severity of COVID-19. This review sheds light on the potential implications of 5-LOX in SARS-CoV-2-mediated infection and the anticipated therapeutic role of 5-LOX inhibitors.

Mahboubi-Rabbani M, Zarghi A. Lipoxygenase Inhibitors as Cancer Chemopreventives: Discovery, Recent Developments and Future Perspectives. Curr Med Chem 2021; 28:1143-1175. [PMID: 31820690 DOI: 10.2174/0929867326666191210104820] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 10/31/2019] [Accepted: 11/10/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Leukotrienes (LTs) constitute a bioactive group of Polyunsaturated Fatty Acid (PUFA) metabolites molded by the enzymatic activity of lipoxygenase (LO) and have a pivotal role in inflammation and allergy. Evidence is accumulating both by in vitro cell culture experiments and animal tumor model studies in support of the direct involvement of aberrant metabolism of arachidonic acid (ACD) in the development of several types of human cancers such as lung, prostate, pancreatic and colorectal malignancies. Several independent experimental data suggest a correlation between tumoral cells viability and LO gene expression, especially, 5-lipoxygenase (5-LO). Overexpressed 5-LO cells live longer, proliferate faster, invade more effectively through extracellular matrix destruction and activate the anti-apoptotic signaling mechanisms more intensively compared to the normal counterparts. Thus, some groups of lipoxygenase inhibitors may be effective as promising chemopreventive agents. METHODS A structured search of bibliographic databases for peer-reviewed research literature regarding the role of LO in the pathogenesis of cancer was performed. The characteristics of screened papers were summarized and the latest advances focused on the discovery of new LO inhibitors as anticancer agents were discussed. RESULTS More than 180 papers were included and summarized in this review; the majority was about the newly designed and synthesized 5-LO inhibitors as anti-inflammatory and anticancer agents. The enzyme's structure, 5-LO pathway, 5-LO inhibitors structure-activity relationships as well as the correlation between these drugs and a number of most prevalent human cancers were described. In most cases, it has been emphasized that dual cyclooxygenase-2/5-lipoxygenase (COX-2/5-LO) or dual 5-lipoxygenase/microsomal prostaglandin E synthase-1 (5-LO/mPGES-1) inhibitors possess considerable inhibitory activities against their target enzymes as well as potent antiproliferative effects. Several papers disclosing 5-lipoxygenase activating protein (FLAP) antagonists as a new group of 5-LO activity regulators are also subject to this review. Also, the potential of 12-lipoxygenase (12- LO) and 15-lipoxygenase (15-LO) inhibitors as chemopreventive agents was outlined to expand the scope of new anticancer agents discovery. Some peptides and peptidomimetics with anti-LT activities were described as well. In addition, the cytotoxic effects of lipoxygenase inhibitors and their adverse effects were discussed and some novel series of natural-product-derived inhibitors of LO was also discussed in this review. CONCLUSION This review gives insights into the novel lipoxygenase inhibitors with anticancer activity as well as the different molecular pharmacological strategies to inhibit the enzyme effectively. The findings confirm that certain groups of LO inhibitors could act as promising chemopreventive agents.

Abstract
Developing improved enzyme inhibitors is an effective therapy to counter various diseases. Aiming to build up biologically active templates, a new series of bis-diazoles conjugated with an aryl linker was designed and prepared through a convenient synthetic approach. Synthesized derivatives 6(a-m), having different substitutions at the 2nd position of the imidazole nucleus, depict the scope of present study. These compounds were characterized through spectroscopic methods and further examined for their in vitro enzyme inhibitory potentials against two selected enzymes: α-glucosidase and lipoxygenase (LOX). Overall, this series was found to be effective against α-glucosidase and moderately active against LOX enzyme. Compound 6k was the most potent α-glucosidase inhibitor with IC50 = 54.25 ± 0.67 µM as compared to reference drug acarbose (IC50 = 375.82 ± 1.76 µM). The docked conformation revealed the involvement of substituent's heteroatoms with amino acid residue Gly280 through hydrogen bonding. The most active LOX inhibitor was 6a with IC50 = 41.75 ± 0.04 µM as compared to standard baicalein (IC50 = 22.4 ± 1.3 µM). Docking model of 6a suggested the strong interaction of imidazole's nitrogen with iron atom of the active pocket of enzyme. Other features like lipophilicity, bulkiness of compounds, pi-pi interactions and/or pi-alkyl interactions also affected the inhibiting potentials of all prepared scaffolds.

Abstract
Pyrimidines are aromatic heterocyclic compounds that contain two nitrogen atoms at positions 1 and 3 of the six-membered ring. Numerous natural and synthetic pyrimidines are known to exist. They display a range of pharmacological effects including antioxidants, antibacterial, antiviral, antifungal, antituberculosis, and anti-inflammatory. This review sums up recent developments in the synthesis, anti-inflammatory effects, and structure-activity relationships (SARs) of pyrimidine derivatives. Numerous methods for the synthesis of pyrimidines are described. Anti-inflammatory effects of pyrimidines are attributed to their inhibitory response versus the expression and activities of certain vital inflammatory mediators namely prostaglandin E2, inducible nitric oxide synthase, tumor necrosis factor-α, nuclear factor κB, leukotrienes, and some interleukins. Literature studies reveal that a large number of pyrimidines exhibit potent anti-inflammatory effects. SARs of numerous pyrimidines have been discussed in detail. Several possible research guidelines and suggestions for the development of new pyrimidines as anti-inflammatory agents are also given. Detailed SAR analysis and prospects together provide clues for the synthesis of novel pyrimidine analogs possessing enhanced anti-inflammatory activities with minimum toxicity.

Abstract
The series of pyrazolyl-phthalazine-dione derivatives (PPDs) was subjected to evaluation of their in vitro lipoxygenase (LOX) inhibition and antimicrobial activities. Results obtained for LOX inhibition activities of PPDs showed that all compounds exhibit good to excellent activity, whereby compounds with eudesmic, syringic, vanillic or toluic moiety are the most active. Molecular modelling study was performed to investigate the possible mechanism of action and binding mode of compounds within the LOX active site. Docking results revealed that activity of the examined compounds depends on the functional group ability to create hydrogen bond accepting (HBA) and hydrophobic features (Hy) in the LOX-Ib active site. In addition, all substances were tested for their antibacterial and antifungal activities. The investigated compounds showed better antifungal than antibacterial activity. The highest antifungal activity was on Aspergillus fumigatus ATTC 204305 and Trichoderma viridae ATCC 13233.

Abstract
BACKGROUND Coumarins exhibit a plethora of biological activities, e.g. antiinflammatory and anti-tumor. Molecular hybridization technique has been implemented in the design of novel coumarin hybrids with several bioactive groups in order to obtain molecules with better pharmacological activity and improved pharmacokinetic profile. OBJECTIVE Therefore, we tried to gather as many as possible biologically active coumarin hybrids referred in the literature till now, to delineate the structural characteristics in relation to the activities and to have a survey that might help the medicinal chemists to design new coumarin hybrids with drug-likeness and varied bioactivities. RESULTS The biological activities of the hybrids in most of the cases were found to be different from the biological activities presented by the parent coumarins. The results showed that the hybrid molecules are more potent compared to the standard drugs used in the evaluation experiments. CONCLUSION Conjugation of coumarin with varied pharmacophore groups/druglike molecules responsible for different biological activities led to many novel hybrid molecules, with a multitarget behavior and improved pharmacokinetic properties.

Abstract
The therapeutic limitations and poor management of inflammatory conditions are anticipated to impact patients negatively over the coming decades. Following the synthesis of the first pyrazole-antipyrine in 1887, several other derivatives have been screened for anti-inflammatory, analgesic, and antipyretic activities. Arguably, the pyrazole ring, as a major pharmacophore and central scaffold partly, defines the pharmacological profile of several derivatives. In this review, we explore the structural-activity relationship that accounts for the pharmacological profile of pyrazole derivatives and highlights future research perspectives capable of optimizing current advancement in the search for safe and efficacy anti-inflammatory drugs. The flourishing research into the pyrazole derivatives as drug candidates has advanced our understanding of inflammation-related diseases and treatment.

Abstract
Stratiotes aloides L. is common water plant in central Poland. Due to its expansive character, S. aloides L. can strongly affect the functioning of aquatic ecosystems. S. aloides L. was an important famine plant in central Poland. This plant was commonly collected and cooked until the turn of the 20th century. It has also been used to heal wounds, especially when these are made by an iron implement. The objective of the present work was to study the phenolic profile in the leaves and roots of S. aloides as well as their antioxidant potential and ability to inhibit lipoxygenase (LOX) in the light of their potential bioaccessibility. The dominant compound in its leaves was luteolin-7-O-hexoside-glucuronide (5.84 mg/g DW), whereas the dominant root component was chrysoeriol-7-O-hexoside-glucuronide (0.83 mg/g DW). Infusions from leaves, roots, and their 1:1 (v/v) mixture contained potentially bioaccessible antiradical compounds. S. aloides is a good source of water-extractable reductive compounds. Especially valuable are the leaves of this plant. The roots of S. aloides contained very active hydrophilic compounds able to chelate metal ions. However, their potential bioaccessibility was relatively low. The hydrophilic compounds from the leaves were the most effective XO inhibitors (EC50 = 9.91 mg DW/mL). The water-extractable compounds derived from the leaves and roots acted as uncompetitive LOX inhibitors.

Abstract
Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) for relieving inflammatory reactions can lead to severe side effects. It is of great importance to configure new dosing strategies for alleviating the side effects of NSAIDs. In this work, an enzyme-responsive anti-inflammatory prodrug capable of generating indomethacin upon the trigger of inflammation is developed. A monomer is first prepared after the esterification of carboxyl groups of indomethacin by hydroxyl groups of N-(2-hydroxyethyl) acrylamide. Then, a polymer prodrug, with indomethacin linked through ester bonds on the side chain, is synthesized by free radical polymerization of the monomer. The therapeutic drug component can be triggered to release from the prodrug under the stimulation of cholesterol esterase, mimicking the inflammation environment. On the contrary, there is only a small amount of drug released in the absence of the enzyme. Therefore, the drug can be triggered to release under the stimulation of an environment mimicking inflammation. Furthermore, the in vitro studies at the cellular level indicate that the enzyme-responsive prodrug can efficiently relieve inflammatory responses induced by lipopolysaccharide in RAW264.7 macrophage cells while indicating no cytotoxicity.

Abstract
The aim of this study was to investigate the anti-inflammatory effects of two new isoxazoline-acylhydrazone derivatives: N'-(4-methoxybenzylidene)-6-(4-nitro-benzoyl)-3a,5,6,6a-tetrahydro-4H-pyrrolo[3,2-d]isoxazole-3-carbohydrazide (R-123) and N'-(4-chlorobenzylidene)-6-(4-chlorobenzoyl)-3a,5,6,6a-tetrahydro-4H-pyrrolo[3,2-d]isoxazole-3-carbohydrazide (R-99). An air pouch induced by carrageenan was used for screening the best dose of R-99 and R-123. Using this mouse model, leukocyte migration and cytokine levels (TNF-α and IL-1β) were determined. Paw edema induced by several phlogistic agents and vascular permeability induced by acetic acid were employed to investigate the mechanism of action of the isoxazoline-acylhydrazone derivatives. A docking study was performed with the human histamine H1 receptor to investigate potential antihistaminic activity. Treatment with the compounds reduced leukocyte migration in the air pouch at all doses tested. TNF-α and IL-1β levels were similarly reduced by the two compounds. Vasoactive amines were inhibited in models of paw edema induced by several agents and vascular permeability induced by acetic acid. The docking study suggests that R-99 and R-123 may be inhibitors of the histamine H1 receptor. In conclusion, the results indicate that R-99 and R-123 exhibit promising anti-inflammatory activity related to their ability to inhibit TNF-α, IL-1β, and vasoactive amine production, as well as reduce leukocyte migration and inhibit mast cell degranulation.

Abstract
5-Lipoxygenase activating protein (FLAP) inhibitors attenuate 5-lipoxygenase pathway activity and reduce the production of proinflammatory and vasoactive leukotrienes. As such, they are hypothesized to have therapeutic benefit for the treatment of diseases that involve chronic inflammation including coronary artery disease. Herein, we disclose the medicinal chemistry discovery and the early clinical development of the FLAP inhibitor AZD5718 (12). Multiparameter optimization included securing adequate potency in human whole blood, navigation away from Ames mutagenic amine fragments while balancing metabolic stability and PK properties allowing for clinically relevant exposures after oral dosing. The superior safety profile of AZD5718 compared to earlier frontrunner compounds allowed us to perform a phase 1 clinical study in which AZD5718 demonstrated a dose dependent and greater than 90% suppression of leukotriene production over 24 h. Currently, AZD5718 is evaluated in a phase 2a study for treatment of coronary artery disease.

Platelet-type 12-lipoxygenase deletion provokes a compensatory 12/15-lipoxygenase increase that exacerbates oxidative stress in mouse islet β cells. J Biol Chem 2019; 294:6612-6620.

Abstract
In type 1 diabetes, an autoimmune event increases oxidative stress in islet β cells, giving rise to cellular dysfunction and apoptosis. Lipoxygenases are enzymes that catalyze the oxygenation of polyunsaturated fatty acids that can form lipid metabolites involved in several biological functions, including oxidative stress. 12-Lipoxygenase and 12/15-lipoxygenase are related but distinct enzymes that are expressed in pancreatic islets, but their relative contributions to oxidative stress in these regions are still being elucidated. In this study, we used mice with global genetic deletion of the genes encoding 12-lipoxygenase (arachidonate 12-lipoxygenase, 12S type [Alox12]) or 12/15-lipoxygenase (Alox15) to compare the influence of each gene deletion on β cell function and survival in response to the β cell toxin streptozotocin. Alox12 -/- mice exhibited greater impairment in glucose tolerance following streptozotocin exposure than WT mice, whereas Alox15 -/- mice were protected against dysglycemia. These changes were accompanied by evidence of islet oxidative stress in Alox12 -/- mice and reduced oxidative stress in Alox15 -/- mice, consistent with alterations in the expression of the antioxidant response enzymes in islets from these mice. Additionally, islets from Alox12 -/- mice displayed a compensatory increase in Alox15 gene expression, and treatment of these mice with the 12/15-lipoxygenase inhibitor ML-351 rescued the dysglycemic phenotype. Collectively, these results indicate that Alox12 loss activates a compensatory increase in Alox15 that sensitizes mouse β cells to oxidative stress.
