Bioorg Chem 2024; 153:107779.

Abstract
To facilitate the development of novel agricultural succinate dehydrogenase inhibitor (SDHI) fungicides, we synthesized three series of derivatives by introducing phenyl pyrazole fragments into the structure of pyrazol-4-yl amides. The results of the bioactivity assay showed that most of the target compounds possessed varying degrees of inhibitory activity against the tested fungi. At a concentration of 100 mg/L, the compound B8 exhibited effective protective activity against S. sclerotiorum in vivo. Molecular docking analysis and succinate dehydrogenase (SDH) inhibition assay indicated that B8 was not a potential SDHI. The preliminary antifungal mechanism of studies showed that B8 induced a large amount of reactive oxygen species (ROS) and severe lipid peroxidation damage in S. sclerotiorum mycelium, resulting in mycelial rupture and disruption of the integrity of the cell membrane and leakage of soluble proteins, soluble sugars and nucleic acids. Further transcriptome analysis showed that compound B8 blocked various metabolic pathways by downregulating the differentially expressed genes (DEGs) catalase, disrupting hydrogen peroxide hydrolysis, accelerating membrane oxidative damage, and upregulating neutral ceramidase, accelerating sphingolipid metabolism to disrupt cell membrane structure and cell proliferation and differentiation, potentially accelerating cell death. The above results indicated that the potential target of these dis-pyrazole carboxamide derivatives may be the cell membrane of pathogenic fungi.

Abstract
The increasing resistance displayed by plant phytopathogenic bacteria to conventional pesticides has heightened the urgency for the exploration of novel antibacterial agents possessing distinct modes of action (MOAs). In this study, a series of novel phenylalanine derivatives with the unique structure of acylhydrazone dithioether have been designed and synthesized. Bioassay results demonstrated that most target compounds exhibited excellent in vitro antibacterial activity against Xanthomonas oryzae pv oryzae (Xoo) and Xanthomonas axonopodis pv citri (Xac). Among them, the EC50 values of L3, L4, L6, L21, and L22 against Xoo were 7.4, 9.3, 6.7, 8.9, and 5.1 μg/mL, respectively, superior to that of bismerthiazol (BT) and thiodiazole copper (TC) (41.5 and >100 μg/mL); the EC50 values of L3, L4, L5, L6, L7, L8, L20, L21, and L22 against Xac were 5.6, 2.5, 6.2, 4.1, 4.2, 6.4, 6.3, 3.6, and 5.2 μg/mL, respectively, superior to that of BT and TC (43.3 and >100 μg/mL). An unmodified drug affinity responsive target stability (DARTS) technology was used to investigate the antibacterial MOAs of active compound L22, and the 50S ribosomal protein L2 (RL2) as an unprecedented target protein in Xoo cells was first discovered. The target protein RL2 was then expressed and purified. Furthermore, the in vitro interactions by microscale thermophoresis (Kd = 0.050 μM) and fluorescence titration (Ka = 1.4 × 105 M-1) experiments also demonstrated a strong binding force between compound L22 and RL2. Overall, these results not only facilitate the development of novel antibacterial agents but also establish a reliable method for exploring the targets of bactericides.

Abstract
The thiophene bearing pyrazole derivatives (7a-j) were synthesized and examined for their in vitro cyclooxygenase, 5-lipoxygenase, and tumour inducing factor-α inhibitory activities followed by the in vivo analgesic, anti-inflammatory, and ulcerogenic evaluations. The synthesized series (7a-j) were characterized using 1H NMR, 13C NMR, FT-IR, and mass spectral analysis. Initially, the compounds (7a-j) were evaluated for their in vitro cyclooxygenase, 5-lipoxygenase, and tumour inducing factor-α inhibitory activities and the compound (7f) with two phenyl substituents in the pyrazole ring and chloro substituent in the thiophene ring and the compound (7g) with two phenyl substituents in the pyrazole ring and bromo substituent in the thiophene ring were observed as potent compounds among the series. The compounds (7f and 7g) with effective in vitro potentials were further analyzed for analgesic, anti-inflammatory, and ulcerogenic evaluations. Also, to ascertain the binding affinities of compounds (7a-j), docking assessments were carried out and the ligand (7f) with the highest binding affinity was docked to know the interactions of the ligand with amino acids of target proteins.

Abstract
In recent years, the severity of plant diseases caused by plant pathogenic fungi and viruses has been on the rise. However, there is a limited availability of pesticide chemicals in the market for effectively controlling both fungal and viral infections. To solve this problem, a series of novel pyrimidine derivatives containing a 1,3,4-oxadiazole thioether fragment were synthesized. Among them, compound 6s exhibited remarkable in vivo protection activity against tobacco mosaic virus, demonstrating the superior 50% effective concentration (EC50) value of 0.42 μM, outperforming ningnanmycin (0.60 μM). Meanwhile, compound 6s exhibited remarkable antifungal activity against Botrytis cinerea Pers. in postharvest blueberry in vitro, with an EC50 value of 0.011 μM, surpassing the inhibition rate of Pyrimethanil (0.262 μM). Additionally, compound 6s also demonstrated remarkable curative and protection activities against blueberry fruit gray mold in vivo, with control efficiencies of 54.2 and 60.4% at 200 μg/mL concentration, respectively, which were comparable to those of Pyrimethanil (49.3 and 63.9%, respectively). Scanning electron microscopy showed that the compound 6s-treated hyphae of B. cinerea Pers. in postharvest blueberry became abnormally collapsed and shriveled. Furthermore, the molecular docking simulation demonstrated that compound 6s formed hydrogen bonds with SER-17, ARG-43, and SER-39 of succinate dehydrogenase (SDH), providing a possible explanation for the mechanism of action between the target compounds and SDH. This study represents the first report on the antiviral and antifungal activities of novel pyrimidine derivatives containing a 1,3,4-oxadiazole thioether fragment.

Abstract
Computer-aided molecular modeling was applied to design a series of Spodoptera frugiperda RyR agonists. Comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) were used to generate 3D-QSAR models. MD simulations in the complex with S. frugiperda native, mutant RyR, and mammalian RyR1 under physiological conditions were used to validate the detailed binding mechanism. Binding free energy calculation by molecular mechanics generalized surface area (MM-GBSA) explained the role of key amino acid residues in ligand-receptor binding. Therefore, 14 new compounds were effectively designed and synthesized, and a bioassay indicated that compounds A-2 and A-3 showed comparable activity to that of chloranthraniliprole with LC50 values of 0.27, 0.18, and 0.20 mg L-1, respectively, against S. frugiperda. Most target compounds also displayed good activity against Mythinma separata at 0.1 mg L-1. Molecular docking and MM-GBSA calculations demonstrated that A-3 had a better binding capacity with native and mutant S. frugiperda RyRs.

Abstract
To investigate the effect of spatial configuration on the biological activity of the compounds, a series of chiral mandelic acid derivatives with a moiety of 1,3,4-oxadiazole thioether have been designed and synthesized. Bioassay results demonstrated that most title compounds with the S-configuration exhibited better in vitro antifungal activity against three plant fungi, such as H3' (EC50 = 19.3 μg/mL) against Gibberella saubinetii, which was approximately 16 times higher than that of H3 (EC50 = 317.0 μg/mL). CoMFA and CoMSIA models were established for 3D-QSAR analysis and provided an important support for further optimization of this series of compounds. Comparing the preliminary mechanism studies between enantiomers (H3 and H3') found that the S-configuration compound (H3') exhibited a stronger ability to destroy the surface structure of G. saubinetii mycelia, causing the leakage of intracellular substances to accelerate and the growth of the hyphae to be inhibited. The results provided a novel view for the further optimization of this series of active compounds and deep mechanism study of chiral pesticides.

Abstract
3-Amino-4,6-dimethylpyrazolopyridine was applied as a precursor for the synthesis of some new pyridopyrazolo-triazine and pyridopyrazolo-triazole derivatives through diazotization, followed by coupling with many 2-cyanoacetamide compounds, ethyl 3-(phenylamino)-3-thioxopropanoate, 3-oxo-N-phenylbutanethioamide, and α-bromo-ketone reagents [namely; 2-bromo-1-(4-fluorophenyl)ethan-1-one, 5-bromo-2-(bromoacetyl)thiophene, 3-(2-bromoacetyl)-2H-chromen-2-one and/or 3-chloroacetylacetone]. The prepared compounds were identified by spectroscopic analyses as IR, 1H NMR, and mass data. The anticancer activity of these pyrazolopyridine analogues was investigated in colon, hepatocellular, breast, and cervix carcinoma cell lines. The pyridopyrazolo-triazine compound 5a substituted with a carboxylate group gave a distinguished value of IC50 = 3.89 µM against the MCF-7 cell line compared to doxorubicin as a reference drug. Also, the pyridopyrazolo-triazine compound 6a substituted with the carbothioamide function gave good activity toward HCT-116 and MCF-7 cell lines with IC50 values of 12.58 and 11.71 µM, respectively. The discovered pyrazolopyridine derivatives were studied theoretically by molecular docking, and this study exhibited suitable binding between the active sides of pyrazolopyridine ligands and proteins (PDB ID: 5IVE). The pyridopyrazolo-triazine compound 6a showed the highest free binding energy (- 7.8182 kcal/mol) when docked inside the active site of selected proteins.

Abstract
Plant diseases can seriously affect the growth of food crops and economic crops. To date, pesticides are still among the most effective methods to prevent and control plant diseases worldwide. Consequently, to develop potential pesticide molecules, a series of novel 2-phenylglycine derivatives containing 1,3,4-oxadiazole-2-thioethers were designed and synthesized. The bioassay results revealed that G19 exhibited great in vitro antifungal activity against Thanatephorus cucumeris with an EC50 value of 32.4 μg/mL, and in vivo antifungal activity against T. cucumeris on rice leaves at a concentration of 200.0 μg/mL (66.9 %) which was close that of azoxystrobin (73.2 %). Compounds G24 (80.2 %), G25 (89.4 %), and G27 (83.3 %) exhibited impressive in vivo inactivation activity against tobacco mosaic virus (TMV) at a concentration of 500.0 μg/mL, which was comparable to that of ningnanmycin (96.3 %) and markedly higher than that of ribavirin (55.6 %). The antibacterial activity of G16 (63.1 %), G26 (89.9 %), G27 (78.0 %), and G28 (68.0 %) against Xoo at a concentration of 50.0 μg/mL was higher than that of thiadiazole copper (18.0 %) and bismerthiazol (38.9 %). Preliminary mechanism studies on the antifungal activity against T. cucumeris demonstrated that G19 can affect the growth of mycelia by disrupting the integrity of the cell membrane and altering the permeability of the cell. These studies revealed that the amino acid derivatives containing a 1,3,4-oxadiazole moiety exhibited certain antifungal, antibacterial, and anti-TMV activities, and these derivatives can be further modified and developed as potential pesticide molecules.

Abstract
We have synthesized novel pyrazolo-quinoline analogues (P1-10) in an effort to create newer antitubercular drugs against the rising bacterial resistance. NMR, IR and ESI-MS spectra were utilized to characterize the synthesised compounds. The antitubercular activity of the target compounds was evaluated against Mycobacterium tuberculosis. Six derivatives (P1-6) displayed very significant activity at 1.6 µg/mL concentration and were found to be more active than pyrazinamide standard. Thus, as per the drug susceptibility results the MIC value could be considered between 1.6 and 0.8 µg/mL. In addition, all the synthesised compounds were subjected to molecular docking studies against specific protein, Enoyl acyl carrier protein reductase (InhA) in complex with N-(4-methylbenzoyl)-4-benzylpiperidine, PDB ID: 2NSD. Among all the compounds the most effective compounds were found an Autodock score of 11.6 and 11.2 against 2NSD, respectively. Further, Zebrafish larvae have been used to test the teratogenicity of the synthesised compounds. There were no indications of abnormalities with (P2), (P4), (P5), (P6), and (P10) at 0.5 µM.

[PMID: 35782313 PMCID: PMC9232256 DOI: 10.1016/j.molstruc.2022.133581] [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: 04/10/2022] [Revised: 06/12/2022] [Accepted: 06/22/2022] [Indexed: 02/08/2023]
Abstract
Synthesis of a new series of spiropyrazole derivatives using microwaves irradiation with high yield in minutes was achieved through a cycloaddition reaction of nitrile imines and arylidenes of 5-bromo-indan-1-one. The structure of the new spiropyrazoles was assured based on their available spectral analyses and the comparison of the extracted data with the literature reports. Molecular docking simulations of all new synthesized spiropyrazole derivatives into leucyl-tRNA synthetase editing domain of Candida albicans (Pdb: 2WFC) indicated that about seven spiropyrazole derivatives can fit deeply in the active site via the formation of stable complexes. In addition, the docking study was utilized to tested the ability of these spiropyrazoles to inhibit COVID-19 through the interaction with COVID-19 main protease (Pdb: 6LU7). The results were surprising which revealed high docking score ranging from -7.764 to -5.9464 kcal/mol. Moreover, the nitrogen atom of pyrazole, Br atom and the C=O group of indanone are essential parts in the binding mode of almost the active derivatives. The results of the docking study are a glimmer of hope to complete the study on these compounds and examine them in the laboratory to ensure their effectiveness as antimicrobials and antiviral, especially Covid-19. Moreover, pharmacokinetics and physicochemical properties were studied.

Abstract
Oxadiazole is a five-membered heterocyclic compound containing two nitrogen atoms and one oxygen atom. The 1,3,4-oxadiazole and 1,2,4-oxadiazole have favourable physical, chemical, and pharmacokinetic properties, which significantly increase their pharmacological activity via hydrogen bond interactions with biomacromolecules. In recent years, oxadiazole has been demonstrated to be the biologically active unit in a number of compounds. Oxadiazole derivatives exhibit antibacterial, anti-inflammatory, anti-tuberculous, anti-fungal, anti-diabetic and anticancer activities. In this paper, we report a series of compounds containing oxadiazole rings that have been published in the last three years only (2020-2022) as there was no report or their activities described in any article in 2019, which will be useful to scientists in research fields of organic synthesis, medicinal chemistry, and pharmacology.

Abstract
Some bioactive derivatives of indeno[1,2- c ]pyrazolones were synthesized through the reaction of phenylhydrazine, different aldehydes and indan-1,2,3-trione at room temperature in acetonitrile. Analytical and spectroscopic studies have confirmed the structural characteristics of the synthesized compounds. In addition, the target compounds were screened for the in-vitro antiproliferative properties against the B16F10 melanoma cancer cell line by the standard MTT assay. The effect on inflammatory marker cyclooxygenase 2 and matrix metalloproteinase 2, 9 was also checked to determine the anti-inflammatory and anti-cell migratory properties of these compounds. The final compounds were also tested for their tyrosinase inhibitory activity. Among all compounds, screened for anticancer activity, three compounds 4e , 4f and 4h reduced the cell proliferation significantly comparable to that of the positive standard drug erlotinib (IC 50 = 418.9±1.54 µM) with IC 50 values ranging from 20.72-29.35 µM. The compounds 4c-4h decreased the COX-2 expression whereas the MMP 2, 9 expressions were significantly reduced by 4a , 4b and 4h . This was confirmed by molecular docking studies, as 4e , 4f and 4h displayed good interactions with the active site of BRAF protein. The compounds 4b , 4f and 4h exhibited moderate tyrosinase inhibition effect as compared to α-MSH. Collectively, compound 4h can be considered as a candidate for further optimization in the development of anticancer therapies based on the results of biological investigations in this study.

Abstract
4-Hydroxyphenylpyruvate dioxygenase (HPPD) is an important target for the development of new herbicides. HPPD inhibitors can hinder photosynthesis and induce weed death with bleaching symptoms. To explore the novel skeleton of HPPD inhibitors, a series of novel pyrazole amide derivatives were synthesized and evaluated for their inhibitory effects on Arabidopsis thaliana HPPD (AtHPPD) and herbicidal activities. Some compounds had excellent inhibitory activities against AtHPPD. Among them, compound B5 displayed top-rank inhibitory activity against AtHPPD with an IC50 value of 0.04 μM, which was obviously superior to that of topramezone (IC50 value of 0.11 μM). Furthermore, compounds B2 and B7 had 100% herbicidal activities in Petri dish assays against Portulaca oleracea and Amaranthus tricolor at 100 μg/mL. In particular, compound B7 not only possessed strong AtHPPD inhibitory activity but also exhibited significant preemergence herbicidal activity. However, compound B7 was completely harmless to soybean, cotton, and wheat. In addition, the molecular docking and microscale thermophoresis measurement experiment verified that compounds can bind well with AtHPPD via π-π interactions. The present work provides a new approach for the rational design of more effective HPPD inhibitors, and pyrazole amides could be used as useful substructures for the development of new HPPD inhibitors and preemergence herbicidal agents.
