Discovery of novel pyrazole derivatives as a potent anti-inflammatory agent in RAW264.7 cells via inhibition of NF-kappa B for possible benefit against SARS-CoV-2

Due to unavailability of a specific drug/vaccine to attenuate severe acute respiratory syndrome coronavirus 2, the current strategy to combat the infection has been largely dependent upon the use of anti-inflammatory drugs to control cytokines storm responsible for respiratory depression. Thus, in this study, we discovered novel pyrazole analogs as a potent nuclear factor kappa B (NF-kappa B) inhibitor. The compounds were assessed for NF-kappa B transcriptional inhibitory activity in RAW264.7 cells after stimulation with lipopolysaccharides (LPS), revealing Compound 6c as the most potent analog among the tested series. The effect of Compound 6c was further investigated on the levels of interleukin-1 beta, tumor necrosis factor-alpha, and interleukin-6 in LPS-stimulated RAW267.4 cells by enzyme immunoassay, where it causes a significant reduction in the level of these cytokines. In Western blot analysis, Compound 6c also causes the inhibition of inhibitor kappa B-alpha and NF-kappa B. It was found to be snugly fitted into the inner grove of the active site of NF-kappa B by forming H-bonds and a nonbonded interaction with Asn28 in a docking analysis.

Rapid four-component synthesis of dihydropyrano[2,3-c]pyrazoles using nano-eggshell/Ti(IV) as a highly compatible natural based catalyst

Nano-eggshell/Ti(IV) as a novel naturally based catalyst was prepared, characterized and applied for the synthesis of dihydropyrano[2,3-c]pyrazole derivatives. The characterization of nano-eggshell/Ti(IV) was performed using Fourier Transform Infrared spectroscopy, X-ray Diffraction, Field Emission Scanning Electron Microscopy, Energy-Dispersive X-ray Spectroscopy, and Thermo Gravimetric Analysis. Dihydropyrano[2,3-c]pyrazoles were synthesized in the presence of nano-eggshell/Ti(IV) via a four component reaction of aldehydes, ethyl acetoacetate, malononitrile and hydrazine hydrate at room temperature under solvent free conditions. The principal affairs of this procedure are mild condition, short reaction times, easy work-up, high yields, reusability of the catalyst and the absence of toxic organic solvents.

Synthesis, characterization, cytotoxicity, and molecular docking studies of ampyrone-based transition metal complexes

A novel series of mononuclear transition metal complexes, [Cu(L)Cl]1, [Zn(L)Cl]2, [Pd(L)Cl]3, [Cd(L)I]4, [Pt(L)Cl]5, and [Hg(L)Cl]6, was constructed from a pyrazole-derived Schiff ligand,HL, and characterized by physicochemical and spectroscopic methods. Fourier-transform infrared (FT-IR) spectral data showed the studied ligand to be tridentate and coordinated to the metal ions via ONO donor atoms, whereas powder X-ray diffraction (PXRD) analysis revealed the crystalline nature of all the complexes. The in vitro cytotoxicity of the studied ligand and its complexes were tested by the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay against the human colorectal cancer cell lines HCT116 and HT29. The results suggested that the HCT116 cell line is highly sensitive to complex1with a half-maximal inhibitory concentration (IC50) of 45.6 mu M, while both cell lines tolerated complexes2and4better in comparison withHL. In addition, complex1with significant anticancer activity was analyzed by molecular docking studies to explore its binding efficacy to the cyclin-dependent kinase 2 active site.

Tungstic acid (H4WO5) immobilized on magnetic-based zirconium amino acid metal-organic framework: An efficient heterogeneous Bronsted acid catalyst for l-(4-phenyl)-2,4-dihydropyrano[2,3c]pyrazole derivatives preparation

A new magnetic nanocatalyst based on the immobilization of tungstic acid onto new design robust, cost-effective, green, and scalable zirconium-L-aspartate amino acid metal-organic framework (MOF)-grafted L-(+)-tartaric acid stabilized magnetite nanoparticles (Fe3O4/tart-NPs) was synthesized by two successive solvo (hydro)-thermal methods. This catalyst was characterized by Fourier-transform infrared (FT-IR), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller (BET), Barrett-Joyner-Halenda (BJH), zeta potential, Thermogravimetry Analysis-Differential Thermal Analysis (TGA-DTA), and vibrating sample magnetometer (VSM) analyses. This catalyst is outstanding to prepare l-(4-phenyl)-2,4-dihydropyrano[2,3-c] pyrazole derivatives in aqueous media due to the open metal sites, high and steady proton conductivity in the zirconium-MOF, MIP-202(Zr), and MOF and also due to Bronsted acid properties of tungstic acid. This acidic catalyst can easily be extracted by an outward magnetic field after completion of the reaction without any deactivation or selectivity loss. The products were characterized by spectroscopic analysis (FT-IR, H-1-NMR, and C-13-NMR). The optimized reaction conditions and a possible reaction mechanism are outlined.

Inorganic and organic anion sensing by azole family members

Anion sensing is one of the most important aspects of chemistry and interest towards anion sensing, directly or indirectly, is evident from publications of the last two decades. Anion sensing is an induced response in a receptor in terms of an optical change (color change, UV-Vis and fluorescence) or an electrochemical change due to the recognition of one or more anions. A variety of ligands, including amides, urea, crown ethers etc., have been utilized from time to time as a sensor for both cations and anions. Simple azoles as well as azoles bearing organic molecules exhibit great potential for anion sensing and have been widely used for the sensing of inorganic and organic anions. This review is focused on various azole members (imidazole, pyrazole, triazole, tetrazole and benzimidazol) and has classified them into groups for the recognition of inorganic and organic anions, and also the recognition of ions by their respective metal complexes.

Approaches to the Synthesis of Dicarboxylic Derivatives of Bis(pyrazol-1-yl)alkanes

Carboxylation of bis(pyrazol-1-yl)alkanes by oxalyl chloride was studied. It was found that 4,4 ‘-dicarboxylic derivatives of substrates with electron-donating methyl groups and short linkers (from one to three methylene groups) can be prepared using this method. Longer linkers lead to significantly lower product yields, which is probably due to instability of the intermediate acid chlorides that are initially formed in the reaction with oxalyl chloride. Thus, bis(pyrazol-1-yl)methane gave only monocarboxylic derivative even with a large excess of oxalyl chloride and prolonged reaction duration. An alternative approach involves the reaction of ethyl 4-pyrazolecarboxylates with dibromoalkanes in a superbasic medium (potassium hydroxide-dimethyl sulfoxide) and is suitable for the preparation of bis(4-carboxypyrazol-1-yl)alkanes with both short and long linkers independent of substitution in positions 3 and 5 of pyrazole rings. The obtained dicarboxylic acids are interesting as potential building blocks for metal-organic frameworks.

Synthesis, antimicrobial studies, and molecular docking of some new dihydro-1,3,4-thiadiazole and pyrazole derivatives derived from dithiocarbazates

A series of 3-acetyl-2-aryl-5-methylthio-2,3-dihydro-1,3,4-thiadiazoles 3a-g, N- (4-acetyl-5-aryl-4,5-dihydro-1,3,4-thiadiazol-2-yl) acetamide derivatives 5a-e and spiro-compound 7 was prepared from starting material dithiocarbazates using N-methylpyrrolidone (NMP) /acetic anhydride mixture. Furthermore, a new series of 5-amino-3- (methylthio) -1-substituted-1H-pyrazole-4-carbonitrile derivatives 12a-d was prepared using two synthetic routes: (i) via reaction of bis (methylthio) methylene malononitrile 8 with carbothiohydrazides 11a-d, or (ii) via reaction of methyl 5-amino-4-cyano-3- (methylthio) -1H-pyrazole-1-carbodithioate 9a with primary/secondary amines. The antimicrobial screening of newly synthesized compounds revealed that compounds 3b, 7, and 12d are the most potent against the Gram-positive (S. aureus) and the Gram-negative (E. coli) bacteria compared to ciprofloxacin as reference drug. Mechanistically, the theoretical docking results of 3b, 7 and 12d suggested that they may act as potent inhibitors of theDNA gyrase.

Synthesis, Bioactivity Evaluation, 3D-QSAR, and Molecular Docking of Novel Pyrazole-4-carbohydrazides as Potential Fungicides Targeting Succinate Dehydrogenase

Main observation and conclusion To screen novel antifungal agents targeting the succinate dehydrogenase (SDH), a series of pyrazole-4-carbohydrazides were rationally designed, synthesized, and characterized under the guidance of the structures of succinate dehydrogenase inhibitors (SDHIs). Bioassay results in vitro indicated that most of the target compounds exhibited excellent activity against Rhizoctonia solani (R. solani), Fusarium graminearum (F. graminearum), Botrytis cinerea (B. cinerea) and Colletotrichum capsica (C. cinerea). Compounds 7d, 7l, 7t and 7x were identified as the most promoting candidates, and their anti-F. graminearum EC50 values were as low as 0.56, 0.47, 0.46 and 0.49 mu g/mL, respectively, presenting the similar antifungal activity as that of the commonly used fungicide carbendazim (0.43 mu g/mL). The 3D-QSAR models were built for a systematic structure-activity relationship profile to explore more potent pyrazole-4-carbohydrazides as novel fungicides. Molecular docking of 7d, 7l and 7r with SDH was performed to reveal the binding modes in active pocket and analyze the interactions between the molecules and the SDH protein. [GRAPHICS] .
