In the present study, 2, 4-Dihydroxyacetophenone thiosemicarbazone (2,4-DAPTZ) and 2, 6-Dihydroxyacetopheone thiosemicarbazone (2,6-DAPTZ) were synthesized by the refluxing method. The structure of the synthesized compounds were characterized by using spectroscopic techniques such as: 1H NMR,13C NMR, IR and UV-Vis. In Silico Molecular docking, ADMET profiling, drug-likeness evaluation, and PASS prediction analyses were carried out to assess the drug potential of the synthesized compounds. Molecular docking was conducted against the BRAF and TGF-β1 proteins (PDB IDs: 6V34 and 3RJR), revealing moderate binding affinities through conventional hydrogen bonding interactions, with docking scores ranging from −5.9 to −6.6 kcal/mol. Furthermore, molecular docking also done with the known inhibitor of proteins i.e Vemurafenib and Galunisertib taking them as control for the comparative study. Both compounds exhibited favorable ADMET characteristics and satisfied key drug-likeness criteria. Furthermore, PASS prediction indicated promising Pa values for anti-tuberculosis, anti-viral, and anticarcinogenic activities. These findings suggest that 2,4-DAPTZ and 2,6-DAPTZ possess significant potential as lead candidates for further In vitro biological evaluation and therapeutic development.

The Wittig reaction is widely used for alkene synthesis. However, the excessive use of Wittig reagents frequently results in phosphorus-containing impurities. The purification of products with very low polarity - characterized by retention factors greater than 0.5 in petroleum ether when monitored via thin-layer chromatography - poses a challenge for conventional column chromatography. Notably, phosphorus-containing compounds exhibit sensitivity to metals, potentially interfering with subsequent reactions. In this study, we demonstrate that low-polarity phosphorus-containing impurities generated during the Wittig reaction can be transformed into high-polarity derivatives using readily available laboratory reagents. This modification facilitates their removal via rapid column chromatography, yielding alkenes free from phosphorus contaminants.

Eight new furan-/pyridine aminophosphonate derivatives A1–A4 and B1–B4 were synthesized by a one-pot Kabachnik–Fields reaction of diethyl phosphite with furfural (pyridine-2-aldehyde) and four different amines with phenyl group. The structures of the synthesized compounds were elucidated by the spectral analysis using 1H,13C and 31P NMR as well as IR and FTMS. The results of antioxidant experiments showed that compounds A3 and B3 display intermediate antioxidant activity at the concentration range of 1–100 µM and IC50 value of 2.02 µM and 2.87 µM, respectively. According to the results of antimicrobial experiments, these eight compounds showed differently strong anti-fungal and antibacterial activity in the concentration range of 125–1000 μg/mL. Fluorescent experiments revealed that the emission wavelength range of A1–A4 and B1–B4 is between 650 nm and 750 nm at the concentration of 1 × 10−5 mol/L. A single crystal of B2 was selected for X-ray crystallography. The compound crystallizes in a monoclinic system with space group C2/c.

Vitamin K3 is a synthetic member of Vitamin K group used as a nutritional supplement. The best recyclable and very efficient heterogenous catalysts containing piperazine substituents used in the green synthesis of vitamin K3 without any hazardous waste in short reaction times under microwave power. Firstly, N-methyl-substituted piperazine was coupled with 2,4-dihydroxybenzaldehyde as the route of Mannich reaction and the synthesized compound was reacted with aminosilane modified nano-structured Fe3O4. After, Pd(II) and oxo-V(IV) complexes of the obtained ligant were synthesized and all the synthesized compounds were characterized by using FT-IR, LC-MS/MS, SEM, EDX, TEM, TG/DTG/DTA, XRD and NMR techniques. The microwave assisted catalytic activities of the synthesized nano-Fe3O4 supported Pd(II) and oxo-V(IV) type complexes were investigated in the oxidative catalytic synthesis of vitamin K3 from 2-methyl-napthtalene (2MN) using green oxidant (H2O2). Heterogenous nano-Fe3O4-supported-Pd(II) complex was showed one of the best efficient catalytic activites with highly selectivities compared to the literature. The converison of Fe3O4@SiO2-L-Pd(II) complex was calculated as 91.29 ± 0.37% with a selectivity of 72.39 ± 0.46%. Fe3O4@SiO2-LOV(IV) complex was conversed the substrate with 88.56 ± 0.48% and 61.25 ± 0.24 selectivity. Pd(II) complex can be used in five cycles as an efficient catalyt in the recycles process with a selectivity of 45.57 ± 0.41% in the 91.33 ± 0.29% conversion.

In this study, a series of novel sulfone derivatives incorporating 1,3,4-oxadiazole and pyrimidine moieties were synthesized and confirmed their structures by 1H NMR,13C NMR, and HRMS. Their in vitro antifungal activities of the target compounds against Dothiorella gregaria (D. gregaria), Diaporthe phaseolorum (D. phaseolorum), Daldinia childiae (D. childiae), Colletotrichum godetiae (C. godetiae), Fusarium tricinctum (F. tricinctum), Neofusicoccum parvum (N. parvum), Botryosphaeria dothidea (B. dothidea), and Epicoccum sorghinum (E. sorghinum) at 100 and 50 µg/mL were determined by the mycelium growth rate method. The bioassay results demonstrate that the target compounds exhibit comparatively lower antifungal activities against the eight plant pathogenic fungi in comparison to imazalil sulfate. To the best of our knowledge, this study presents the first report on the synthesis and antifungal activity evaluation of sulfone derivatives incorporating 1,3,4-oxadiazole and pyrimidine moieties.

This work studied the effects of gamma radiation on the structural and optical properties of SnO2 thin films in a dose-dependent manner. The microstructural change was confirmed by peak shifting, peak broadening, and changes in grain size with an increase in radiation dose, as observed from X-ray diffraction analysis. Changes in the intensity of photoluminescence spectra and optical properties are due to radiation-induced defect states. The obtained results indicate that gamma irradiation can be used to tailor the characteristics of SnO2 for various applications. In contrast to previous works, this study quantitatively connects radiation dose to structural and optical transformations, thereby addressing the fundamental mechanisms of defect formation.

The decline in black gram yield was primarily linked to rainfed crops, poor nutrient management, inadequate assimilate partitioning, flower dropping, poor pod setting, and physiological issues. Fertilizers with foliar spray at the reproductive stage in pulse could aid it by directly delivering the nutrients to the site of food synthesis, resulting in a faster food supply and improved crop performance. The trials were conducted to assess the efficacy of silixol on black gram growth and yield as well as soil health. Treatments including 50% RDF combined with vermicompost (VC), silixol granules soil application (SA), and silixol foliar spray (FS) are examined in the RCBD with three replications. Results revealed that 50% RDF + VC at 2.5 t/ha + silixol granules (SA) at 20 kg/ha + silixol (FS) at 1% on 40 DAS showed significant improvement in plant height (67.5 cm), DMP (1959 kg/ha), LAI (2.24), chlorophyll content (94.95 SPAD value) on 60 DAS, root nodules (667 Nos/plant) and grain yield (849 kg/ha) with 61% increase over RDF alone. Similarly, an increase in the soil microbial biomass carbon, dehydrogenase activity, and microbial population by 16.0%, 59.6% and 31.8%, respectively were by applying silixol granules with foliar spray in combination with integrated fertilization over control.

Results revealed that 50% RDF + VC at 2.5 t/ha + silixol granules (SA) at 20 kg/ha + silixol (FS) at 1% on 40 DAS showed significant improvement in plant height (67.5 cm), DMP (1959 kg/ha), LAI (2.24), chlorophyll content (94.95 SPAD value) on 60 DAS, root nodules (667 Nos/plant) and grain yield (849 kg/ha) with 61% increase over RDF alone. Similarly, an increase in the soil microbial biomass carbon, dehydrogenase activity, and microbial population by 16.0%, 59.6% and 31.8%, respectively were by applying silixol granules with foliar spray in combination with integrated fertilization over control.</div></div>","PeriodicalId":20056,"journal":{"name":"Phosphorus, Sulfur, and Silicon and the Related Elements","volume":"200 7","pages":"Pages 596-611"},"PeriodicalIF":1.4,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144587488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Morocco is one of the world’s leading phosphate producers, converting its phosphate reserves into phosphoric acid, which is further used to produce urea phosphate. Urea phosphate is a valuable source of nitrogen and phosphorus for plant growth. However, phosphoric acid purification in Morocco is crucial to ensure high-quality urea phosphate production. In this study, we synthesized urea phosphate via an exothermic reaction of urea and phosphoric acid under optimized conditions for 90 min. Crystals began to form after 60 min, and the final sample was taken after 90 min. Elemental and morphological analyses confirmed the high purity of the synthesized urea phosphate crystals. XRD and FT-IR analyses verified the crystalline phase and elemental composition, focusing on nitrogen (N) and phosphorus (P2O5), important nutrients for crops. SEM and microscopy further demonstrated the excellent quality of the final product. Our results suggest that untreated Moroccan phosphoric acid can be effectively used to produce pure urea phosphate crystals, thus providing an effective solution for improving agricultural productivity.

A total of 28 new ferulic acid derivatives bearing the sulfonamide moiety were designed and synthesized, followed by an evaluation of their antibacterial activities. The structures of the synthesized compounds (B1 − B28) were fully characterized using 1H NMR,13C NMR, and HRMS techniques. Among them, the structure of compound B11 was further elucidated through X-ray single-crystal diffraction analyses. Bioassay results indicated that several target compounds exhibited significant inhibitory activity against the tested plant pathogens in vitro. Notably, compound B28 demonstrated the highest resistance to Xanthomonas oryzae pv. oryzicola (Xoc), with an EC50 (half-maximal effective concentration) value of 28.6 μg/mL, which was more than twice as effective as the control agents zinc thiazole (EC50 = 74.4 μg/mL) and thiodiazole copper (EC50 = 97.1 μg/mL). Mechanistic studies revealed that B28 enhances bacterial membrane permeability and disrupts cell morphology. This work highlights promising candidates for agricultural antibacterial applications.
