Single crystal X-ray diffraction studies showed that the complex crystallizes in a square pyramidal geometry and belongs to the monoclinic crystal system with the space group <em>P</em>2<sub>1</sub>/<em>n</em>.

The final <em>R</em><sub>1</sub> was 0.0380 (I > 2σ(I)) and <em>wR</em><sub>2</sub> was 0.0972 (all data). The experimental antibacterial activity studies performed using the disc diffusion method revealed that the complex is indeed acting as a good antibacterial agent against <em>Staphylococcus aureus</em> and <em>Escherichia coli.</em> A better understanding of the binding mechanisms was uncovered through comparative molecular docking investigations. The docking score for the target <em>S. aureus glyrase</em> complex with DNA (PDB id-2XCS) was found to be -7.1 kcal/mol, while the docking score for dialkylglycine decarboxylase (PDB id-1D7U) was -5.2 kcal/mol. The high docking score of the complex with the target protein allowed the complex to act as a potential antibacterial agent. These results were also supported by other theoretical studies such as DFT calculations and pharmacokinetic studies. The correlation between the HOMO-LUMO energy gap and antibacterial activity was studied computationally. Hirshfeld surface analysis and pharmacokinetic studies were also performed for this crystal for a better understanding of the intermolecular interactions and ADME properties.</p><p><img src="/public/site/images/arslanh/14_4_429_438.png" alt="" /></p>2023-12-31T00:00:00+03:00Copyright (c) 2023 Authorshttps://www.eurjchem.com/index.php/eurjchem/article/view/2471Synthesis of coumarin-3-carboxylic acids in waste curd water: A green approach2023-12-31T09:18:05+03:00Nitin Bhaidas SonawaneJamatsing Dabarsing RajputDilip Ramsing Patil<p>An efficient and green protocol has been developed for the synthesis of derivatives of coumarin-3-carboxylic acid using waste curd water as a catalytic solvent. Curd water successfully catalyzes the reaction of 2-hydroxybenzaldehydes with dimethyl malonate under ultrasonic irradiation (40 °C) to construct different scaffolds of coumarin-3-carboxylic acid, with good to outstanding yields. The use of biodegradable solvents, sustainability, low reaction duration, mild reaction conditions without metals and Lewis acids, excellent yields, and compatibility with a wide range of electronically diverse substrates are all advantages of this synthesis process. Acidic curd water, which acts as a biological catalyst as well as a solvent for the reaction under ultrasonic irradiation, may be a better green alternative to some standard methods for synthesizing coumarin-3-carboxylic acids.</p><p><img src="/public/site/images/arslanh/14_4_439_444.png" alt="" /></p>2023-12-31T00:00:00+03:00Copyright (c) 2023 Authorshttps://www.eurjchem.com/index.php/eurjchem/article/view/2445Isotopic study of rainfall and definition of local meteoric water lines: Case of the rainfall stations of the city of Bangui in Central African Republic2023-12-31T09:18:05+03:00Eric FotoOscar AllahdinOlga BitemanNicole Poumaye<p>The study of the isotopic composition of rainwater discussed in this article allows isotopic characterization of rainfall recorded in the Bangui region over 11 years at two stations. It will highlight the relationships between isotopes, climatic parameters, and temporal variation before defining the local meteoric line, which constitutes the reference point for the region. The results obtained after a follow-up of eleven years without interruption showed two major physical effects, the effect of the rainfall influences more strongly the composition in isotopes, the contents in isotopes vary inversely with the precipitation. For example, heavy rainfall in August and September saw a strong depletion of δ¹⁸O and δ²H contents. These values reach up to -4.96‰ for δ¹⁸O and -28.3‰ for δ²H. Similar, although weaker, effects are observed for July and October precipitation. We also note that the isotope contents at the Bangui University station are lower than those measured at the Bangui Sodeca station located at 386 m altitude on the Lower Ubangi Hill, which is similar to a pseudo-altitude effect. The evolution of stable isotope content in water as a function of meteorological parameters (temperature, rainfall, altitude) has allowed us to determine a local meteorological line for the city of Bangui from two measuring stations defined as follows: δ<sup>2</sup>H = 7.6 × δ<sup>18</sup>O + 10.4 (<em>R</em><sup>2 </sup>= 0.9909) Université de Bangui, δ<sup>2</sup>H = 8.4 × δ<sup>18</sup>O + 12.5 (<em>R</em><sup>2 </sup>= 0.9909) Bangui-Sodeca and δ<sup>2</sup>H = 7.9 × δ<sup>18</sup>O + 11.3 (<em>R</em><sup>2</sup> = 0.9939) Bangui local meteoric water lines.</p><p><img src="/public/site/images/arslanh/14_4_445_450.png" alt="" /></p>2023-12-31T00:00:00+03:00Copyright (c) 2023 Authorshttps://www.eurjchem.com/index.php/eurjchem/article/view/2459Toxicological aspects of wastewater2023-12-31T09:18:06+03:00Frantisek OndrasikSarka Krocova<p>‘Alea iacta est', the die is cast, said the Roman general Gaius Julius Caesar the moment he and his troops crossed the Rubicon River. This phrase refers to a state where everything has already been decided and this decision cannot be taken back. It is at this borderline that humanity now finds itself; its survival is at stake. The basic biogenic components of the environment, such as water, air, and soil, are coming under the pressure of the modern industrial revolution. The products of this anthropogenic activity significantly affect the environment. We live in a time of rapid climate change, melting of glaciers, devastation of nature, mass extermination, or loss of animal and plant species in order to increase human living standards. Man has caused all this in one stage of human life, a generation. Humanity mismanages natural resources and clings to a lifestyle that is vain. It destroys the natural environment on which it is dependent simultaneously. An environmental disaster is coming. Will our blue planet still be livable for future generations? The study deals with one of the components of the environmental environment, not an insignificant one, that is, water. For the moment, recycled water is a neglected and underappreciated resource from the point of view of the Czech Republic and its state authorities. The cleaning process may be inadequate or unreliable, and residual biological and chemical contaminants may pose a risk to human health. This work focuses on the use of purified wastewater mainly for firefighting unit activities in relation to a possible health risk. The result of the study is a clear possible recommendation for the use of recycled wastewater from a technical, technological, and logistical point of view, but taking into account the precautionary principle.</p><p><img src="/public/site/images/arslanh/14_4_451_459.png" alt="" /></p>2023-12-31T00:00:00+03:00Copyright (c) 2023 Authorshttps://www.eurjchem.com/index.php/eurjchem/article/view/2456Synthesis of calcium propionate from indigenous limestone from Swat area in Pakistan2023-12-31T09:18:06+03:00Ansar MahmoodSamreen ZahraRashid MahmoodAsma Sheikh<p>In this study, native limestone from the Swat area of Pakistan was used for the synthesis of calcium propionate. The powdered limestone was allowed to react with propionic acid and the effect of the synthesis parameters, that is, the particle size (50, 100, 150, and 200 mesh), propionic acid (10, 15, and 30 %), solid-liquid ratio (0.1:10, 0.12:1, 0.14:1, and 0.16:1), reaction time (1, 1.5, 2, and 2.5 hours) and the temperature (60, 80, 90, and 100 °C) on the percentage yield and purity of calcium propionate was studied. The results showed that the optimum synthesis parameters were 200 mesh particle size, 15% propionic acid concentration, 0.14:1 solid-liquid ratio, 2.5 hours reaction time, and 80 °C temperature. The product obtained under optimal conditions was characterized by infrared spectroscopy, thermogravimetry, and scanning electron microscopy. The results revealed that a product having ≥ 99.8% purity with 85% yield can be obtained by this process.</p><p><img src="/public/site/images/arslanh/14_4_460_465.png" alt="" /></p>2023-12-31T00:00:00+03:00Copyright (c) 2023 Authorshttps://www.eurjchem.com/index.php/eurjchem/article/view/2468Design, synthesis, spectral analysis, and biological evaluation of Schiff bases with a 1,3,4-thiadiazole moiety as an effective inhibitor against bacterial and fungal strains2023-12-31T09:18:06+03:00Sajid Ajit MalakJamatsing Dabarsing RajputMustakim Sharif<p>Many distinct natural and pharmaceutical items include the well-known heterocyclic nucleus 1,3,4-thiadiazole.

Blueberries of the variety (JEWEL) provided by Tierra de blueberries, Oran, Monteros, Tucuman were used. The parameters analyzed were variations of the color and content of polyphenols by HPLC and UV-vis. Polyphenols determined by HPLC were: delfinidin-3-galactoside, delfinidine-3-glucoside, cyanidin-3-galactoside, delfinidin-3-arabinoside, cyanidin-3-glucoside, petunidin-3-galactoside, cyanidin-3-arabinoside, petunidin-3-glucoside, peonidin-3-galactoside, petunidin-3-arabinoside, malvidin-3-galactoside and malvidin-3-glucoside. From the results obtained, it is concluded that the polyphenol content varied in the irradiated fruits and in the untreated fruits as a function of time, with the values being closest to the initial time value (control) in the case of irradiated fruits. There were no appreciable differences in color change due to irradiation. At time 0, the color difference in the whole fruit between the treated sample (IFC0) and the standard (NFC0) gave Δ<em>E</em>* values equal to 2.06. After 3 days, the color difference was 3.08 for the natural sample and 6.06 for the treated sample. For this reason, it is considered that irradiation of blueberries is a very appropriate method for conservation, maintaining the nutritional and quality characteristics of blueberries.</p><p><img src="/public/site/images/arslanh/14_4_473_477.png" alt="" /></p>2023-12-31T00:00:00+03:00Copyright (c) 2023 Authorshttps://www.eurjchem.com/index.php/eurjchem/article/view/2478Synthesis and antimicrobial activity of new ent-kaurene-type diterpenoid derivatives2023-12-31T09:18:06+03:00Andres Eduardo Marquez-ChaconAlida Perez ColmenaresLuis Rojas FerminRosa AparicioFreddy Alejandro RamosAlfredo UsubillagaYsbelia Obregon<p>This research consists in the synthesis of <em>ent-</em>kaurene-type diterpenoid derivatives from the new natural product <em>ent-kaur-3-acetoxy-15-ene,</em> to carry out structural modifications on the C<sub>3</sub> carbon of the <em>ent-</em>kaurene core by introducing different oxygenated groups, especially esters, in order to probe the structure-activity relationship (SAR) against microorganisms.

Analytical integrations of the cases (n, m) = (1, 0) and (0, 1) are based on the Laplace transformation with the integrand exp(-a<sup>2</sup>t<sup>2</sup>), the other cases are based on the Laplace transformation with the integrand exp(-a<sup>2</sup>t) and the two-dimensional version of the Boys function. These analytic expressions, with Gaussian function integrands, are useful for manipulation with higher moments of interelectronic distances, for example, in correlation calculations. The equations derived help to evaluate the one-, two-, and three-electron Coulomb integrals, òρ(1)R<sub>C1</sub><sup>-n</sup>R<sub>D1</sub><sup>-m</sup>d<strong>r</strong><sub>1</sub>, òρ(1)ρ(2)R<sub>C1</sub><sup>-n</sup>r<sub>12</sub><sup>-m</sup>d<strong>r</strong><sub>1</sub>d<strong>r</strong><sub>2</sub>, and òρ(1)ρ(2)ρ(3)r<sub>12</sub><sup>-n</sup>r<sub>13</sub><sup>-m</sup>d<strong>r</strong><sub>1</sub>d<strong>r</strong><sub>2</sub>d<strong>r</strong><sub>3</sub>, wherein ρ(i) is the one-electron density describing the electron clouds in molecules, solids, or any media or ensemble of materials. Analytical solutions to integrals are more useful than numeric solutions; however, the former is not available in many cases. We evaluate these integrals numerically, even more so, the òf(ρ(1))d<strong>r</strong><sub>1</sub> to òf(ρ(1),ρ(2),ρ(3))d<strong>r</strong><sub>1</sub>d<strong>r</strong><sub>2</sub>d<strong>r</strong><sub>3</sub> with the analytical function f. For this task, the commonly used density functional theory numerical integration scheme has been elaborated to 6 and 9 dimensions via Descartes product. More importantly, this numerical integration scheme works not only for Gaussian type but also for Slaterian types. Analogy is commented on in terms of the powerful empirical correction between quantum potential energy correction and the empirically corrected Newton’s universal law of gravity in the explanation of dark matter and energy, as well as its relation to Hartree-Fock and Kohn-Sham formalisms.</p><p><img src="/public/site/images/arslanh/14_4_486_493.png" alt="" /></p>2023-12-31T00:00:00+03:00Copyright (c) 2023 Authorhttps://www.eurjchem.com/index.php/eurjchem/article/view/2485In an attempt to add ligands to the sixth (axial) position of vanadyl bis-acetylacetonate: A unique tetranuclear vanadyl species2023-12-31T09:18:07+03:00Roger LalancetteIvan Bernal<p>We have explored the interaction of [(acac)<sub>2</sub>V=O] (acac = acetylacetone) with a series of potential ligands which were chosen because of their expected ability to attach themselves onto its sixth (axial) position.
