Anti-inflammatory and antinociceptive activity profile of a new lead compound-LQFM219

LQFM219 is a molecule designed from celecoxibe (COX-2 inhibitor) and darbufelone (inhibitor of COX-2 and 5-LOX) lead compounds through a molecular hybridisation strategy. Therefore, this work aimed to investigate the antinociceptive and anti-inflammatory activities of this new hybrid compound. The acute oral systemic toxicity of LQFM219 was evaluated via the neutral red uptake assay. Acetic acid-induced abdominal writhing and CFA-induced mechanical hyperalgesia were performed to evaluate the antinociceptive activity, and the anti-oede-matogenic activity was studied by CFA-induced paw oedema and croton oil-induced ear oedema. Moreover, the acute anti-inflammatory activity was determined by carrageenan-induced pleurisy. In addition, cell migration, myeloperoxidase enzyme activity, and TNF-alpha and IL-1 beta levels were determined in pleural exudate. Moreover, a redox assay was conducted using electroanalytical and DPPH methods. The results demonstrated that LQFM219 was classified as GHS category 4, and it showed better free radical scavenger activity compared to BHT. Besides, LQFM219 decreased the number of writhings induced by acetic acid and the response to the mechanical stimulus in the CFA-induced mechanical hyperalgesia test. Furthermore, LQFM219 reduced oedema formation, cell migration, and IL-1 beta and TNF-alpha levels in the pleural cavity and inhibited myeloperoxidase enzyme activity. Thus, our study provides that the new pyrazole derivative, LQFM219, demonstrated low toxicity, antinociceptive and anti-inflammatory potential in vitro and in vivo.

Discovery of biphenyl pyrazole scaffold for neurodegenerative diseases: A novel class of acetylcholinesterase-centered multitargeted ligands

Multitargeted ligands have demonstrated remarkable efficiency as potential therapeutics for neurodegenerative diseases as they target multiple pathways involved in the progression of these diseases. Herein, we report first-in-class dual inhibitor of acetylcholinesterase (AChE) and tau aggregation as a novel class of multitargeted ligands for neurodegenerative diseases. The reported biphenyl pyrazole scaffold binds monomeric tau with sub-micromolar affinity and impedes the formation of tau oligomers at early stages. Additionally, the lead compound inhibited AChE activity with an IC50 value of 0.35 +/- 0.02 mu M. Remarkably, the neuroprotective effect of this lead in induced cytotoxicity model of SH-SY5Y neuroblastoma cells is superior to single-targeted AChE and tau-aggregation inhibitors. This scaffold would enable development of new generation of multitargeted ligands for neurodegenerative diseases that function through dual targeting of AChE and monomeric tau.

1-Methyl-1H-pyrazole-5-carboxamide Derivatives Exhibit Unexpected Acute Mammalian Toxicity

A series of 1-methyl-1H-pyrazole-5-carboxamides were synthesized as potent inhibitors of the parasitic nematode of sheep, Haemonchus contortus. These compounds did not show overt cytotoxicity to a range of mammalian cell lines under standard in vitro culture conditions, had high selectivity indices, and were progressed to an acute toxicity study in a rodent model. Strikingly, acute toxicity was observed in mice. Experiments measuring cellular respiration showed a dose-dependent inhibition of mitochondrial respiration. Under these conditions, potent cytotoxicity was observed for these compounds in rat hepatocytes suggesting that the potent acute mammalian toxicity of this chemotype is most likely associated with respiratory inhibition. In contrast, parasite toxicity was not correlated to acute toxicity or cytotoxicity in respiring cells. This paper highlights the importance of identifying an appropriate in vitro predictor of in vivo toxicity early on in the drug discovery pipeline, in particular assessment for in vitro mitochondrial toxicity.

Cyclocondensation of 2-Hydroxyimino-1-(naphthalen-1-yl)butane-1,3-dione with Alkyl Hydrazines Leading to Substituted 4-Nitrosopyrazoles

Cyclocondensation of 2-(hydroxyimino)-1-(naphthalen-1-yl)butane-1,3-dione with alkyl hydrazines leading to new 1-alkyl-3(5)-methyl-5(3)-(naphthalene-1-yl)-4-nitrosopyrazoles is described. 8 previously unknown N-alkyl-4-nitrosopyrazoles with a 1-naphthalene substituent at the 3 or 5 position of the pyrazole ring were obtained as a result. It was found that yields of naphthyl-substituted pyrazoles with N-alkyl groups near the naphthalene substituent were significantly lower than for 3-(naphthalen-1-yl)-substituted pyrazoles. Particular yields of pairwise formed isomeric nitrosopyrazoles were associated with the different electrophilicity of the two carbonyl groups of the initial diketone. Using quantum chemical calculations by the DFT method B3LYP-D3/6-311G(d,p), the potential energies of the various conformers were estimated to draw a conclusion about the preferred attack of alkyl hydrazine on the carbonyl group, associated with the naphthalene ring.H-1 NMR and 2D(1)H-C-13 HSQC spectra of the compounds confirmed this direction of the reaction. The crystal structures of the synthesized compounds were established by X-ray powder diffraction technique. Crystal structure data were in agreement with quantum chemical calculations.

Estrogen Receptor 1 (ESR1) Agonist Induces Ovarian Differentiation and Aberrant Mullerian Duct Development in the Chinese Soft-shelled Turtle, Pelodiscus sinensis

Estrogens play critical roles in ovarian and reproductive organ development, but the molecular signaling pathways in non-mammalian vertebrates are not well understood. Studies of reptiles have indicated that administration of exogenous estrogens during embryonic development causes ovarian differentiation and presumptive male to female sex-reversal. The Chinese soft-shelled turtle, Pelodiscus sinensis, belongs to the family Trionychidae and exhibits genotypic sex determination system with ZZ/ZW sex chromosomes. In order to assess the role of estrogens and their signaling pathway on sex determination and differentiation, P sinensis eggs were given a single administration of endogenous estrogen,1713-estradiol (E2) or a synthetic estrogen receptor 1 (ESR1) agonist, 4,4′,4 ”-(4-propyl-[1H]-pyrazole-1,3,5-triyl) trisphenol (PPT) in ovo during gonadal differentiation, and the subsequent effects were examined during a final developmental stage prior to hatching. The administration of both E2 and PPT induced ovarian differentiation in genetic male embryos. Intriguingly, PPT but not E2 induced the Mullerian duct enlargement and aberrant glandular development. These data suggest that ovarian differentiation and reproductive tract anomalies induced by the exogenous estrogen exposure act through ESR1 in the Chinese soft-shelled turtles.

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.

Superparamagnetic Fe3O4@Alginate supported L-arginine as a powerful hybrid inorganic-organic nanocatalyst for the one-pot synthesis of pyrazole derivatives

Hybrid inorganic-organic material Fe3O4@Alg@CPTMS@Arg, was prepared by the layer-by-layer techniques through grafting l-arginine (l-arg) to Fe3O4@Alg using 3-chloropropyltrimethoxysilane (CPTMS) as a linker. Fe3O4@Alg was prepared by in situ co-precipitation of iron (iii) and iron (ii) chloride in the presence alginate (Alg). The hybrid inorganic-organic material was characterized employing various techniques such as Fourier transform infrared (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and vibrating sample magnetometer (VSM). The as-prepared Fe3O4@Alg@CPTMS@Arg nanoparticles mediated the synthesis of pyrazole derivatives withviaone-pot reaction between phenylhydrazine, malononitrile, and various aromatic aldehydes under reflux in ethanol. Recycled catalyst exhibited comparable efficacy after seven cycles. The high catalytic activity, excellent yields, as well as the recyclability of the hybrid nanomaterials with quantitative efficiency, are factors that render this environmentally benign procedure appealing.

Pyrazole-Based Lactate Dehydrogenase Inhibitors with Optimized Cell Activity and Pharmacokinetic Properties

Lactate dehydrogenase (LDH) catalyzes the conversion of pyruvate to lactate, with concomitant oxidation of reduced nicotinamide adenine dinucleotide as the final step in the glycolytic pathway. Glycolysis plays an important role in the metabolic plasticity of cancer cells and has long been recognized as a potential therapeutic target. Thus, potent, selective inhibitors of LDH represent an attractive therapeutic approach. However, to date, pharmacological agents have failed to achieve significant target engagement in vivo, possibly because the protein is present in cells at very high concentrations. We report herein a lead optimization campaign focused on a pyrazole-based series of compounds, using structure-based design concepts, coupled with optimization of cellular potency, in vitro drug-target residence times, and in vivo PK properties, to identify first-in-class inhibitors that demonstrate LDH inhibition in vivo. The lead compounds, named NCATS-SM1440 (43) and NCATS-SM1441 (52), possess desirable attributes for further studying the effect of in vivo LDH inhibition.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 5932-27-4 help many people in the next few years. Name: Ethyl 1H-pyrazole-3-carboxylate.
