Substituted 1,3,4-thiadiazol are well know to have biological activity agent, and to have important uses in the medical, agriculture and industrial application, Several compounds of this group were synthesized from couma...

Abstract We developed SPARFlow, an open-source KNIME workflow for structure–activity or structure–property relationship (SAR/SPR) analyses. The workflow integrates data preprocessing, chemical structure curation, sim...

In this research new compounds containing quinazolin-4(3H)-one nucleus linked to heterocyclic moieties were synthesized using ethyl (4'-oxoquinazolin-3'-yl) acetate (2) as a synthon. This compound was synthesized via 4-q...

In this paper the compounds (11-20) (methyl pyrimidine - 2(1H)-one and others phenyl pyrimidine -2(1H)- one) that will prepared from α, β unsaturated carbonyl compounds they are called chalcones, that compounds prepare...

In this paper the synthesis of  N[(1E)-1- ( 3,5.- disubstituted phenyl -4,5-dihydro-1H- pyrazol-1- yl) ethylidene or methylidene] substituted aniline [13-15] [17-19] and 1,1-{benzene- 1,4- or -1,3- diylbis [nitrilo (E) ...

Three In(III) MOFs based on diphenic acid and nitrogen-donor ancillary ligands were obtained as pure phases. Two of them have 1D chain structures, and the third forms 2D zig-zag layers. The different torsion angles adopt...

The phase equilibrium diagram of the Tm–Cr–Ge ternary system was constructed at a temperature 1070 K based on the results of X-ray phase, microstructural analyzes and energy-dispersive X-ray spectroscopy in the whole...

Isothermal section of the Lu-Ag-Si system at 500ºC was studied by means of X-ray powder diffraction, microstructure and EDX-analyses in the whole concentration range. The existence of earlier reported binary compounds L...

This study comprises two distinct but parallel investigations concerning Haemaphysalis longicornis in Korea: an exploratory ecological survey of vector density across 20 sites in 2023 and a laboratory-based screening of ...

The isothermal section of the phase diagram of the Gd–Cr–Ge ternary system was constructed at 1070 K over the whole concentration range using X-ray diffractometry, metallography and electron microprobe (EPM) analysis...

A rising human impact alters landscape patterns and determines the agriculture–ecology–economy nexus (AEEN), which further threatens the sustainability of social–ecological system (SES). However, the mechanisms thr...

Solid phase microextraction (SPME) coupled to capillary gas chromatography (CGC) and mass spectrometry (MS) was used to evaluate the use of fungal volatiles to discriminate Fusarium species from wheat cultivars in the Ar...

Several new 1,2,5-oxadiazole N-oxide derivatives and some deoxygenated analogues were synthesized to be tested as potential selective hypoxic cell cytotoxins. Compounds prepared were designed in order to gain insight int...

Changes of bentonite surface structure under the influence of direct microwave irradiation during adsorpion of Cu2+ from concentrated solutions were investigated by X-ray and EDS analysis. The microwave treated bentonite...

We present herein an in-depth study on the activity of amidinoquinoxaline N-oxides 1 against Gram-positive and Gram-negative anaerobic bacteria. Based on 5-phenyl-2,3-dihydropyrimidoquinoxaline N-oxide 1a, the selected s...

Two new polyhydroxylated steroids, including one spirostane-type (1) and one pregnane-type (2) skeleton, together with three known analogs, (25R)-spirost-5-en-3β-ol (3), (25S)-5β-spirostane-3β-ol (4), and (25R)-spiros...

Three-dimensional electron diffraction (3D ED) has become increasingly popular over the last two decades, challenging the limits of established single-crystal X-ray diffraction experiments. In particular, continuous-rota...

Abstract Slaughterhouse blood is a by-product of animal slaughter that can be a good source of animal protein. This research purposed to examine the functional qualities of the blood plasma from Hanwoo cattle, black goat...

ABSTRACT Neuroinflammation is a core pathological mechanism in neurodegenerative diseases. Although natural many compounds, derived from traditional Chinese medicine have shown promise in modulating neuroinflammation, co...
