The primary aim of this study is to synthesize metal complexes with superior antimicrobial properties.\u0000Methods: The Schiff base ligand (E)-N'-(1-thiophen-2-yl) ethylidene isonicotinohydrazide was synthesized by reacting isonicotinohydrazide (INH) with 2-acetylthiophene. This Schiff base was utilized to synthesize metal complexes with copper (II), nickel (II), and cobalt (II) ions via the reflux method. The ligand and metal complexes were characterized using various physicochemical techniques, including elemental analysis, conduct metric studies, magnetic susceptibility, FT‐IR, 1H NMR, ESI-MS, and electronic spectral analysis.\u0000Results: All complexes were successfully characterized. The Ni-complex demonstrated the highest cytotoxicity in the brine shrimp lethality bioassay compared to the Cu and Co-complexes. The Ni and Cu-complexes exhibited greater antibacterial efficacy against all bacteria, while the Co-complex showed no activity.\u0000Conclusion: The newly synthesized complexes proved to be highly stable, displaying significant antimicrobial potential. These findings suggest that future modifications to this synthesized series could address specific pharmaceutical needs.","PeriodicalId":322389,"journal":{"name":"International Journal of Chemistry Research","volume":"13 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141849184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To combat these harmful effects, numerous wastewater treatment processes, particularly physicochemical, were implemented. Adsorption techniques are particularly used to find new natural, biodegradable and inexpensive adsorbents to treat colored waste from structures such as medical and pharmaceutical laboratories. The aim of the present study was to carry out a relevant bibliographical review of the physico-chemical and thermodynamic parameters that can influence this adsorption of methylene blue on activated carbons of natural origin. The results showed a remarkable elimination of methylene blue. However, parameters such as particle size, adsorbent mass, pH, contact time, initial methylene blue concentration, agitation speed and temperature showed that the adsorption capacity of MB on biosorbents was influenced by these quantities. Similarly, the positive and negative enthalpy values (ΔH°) indicated that adsorption process could be endothermic or exothermic. Other thermodynamic parameters, such as the negative value of Gibbs free energy (ΔG°) and the positive value of entropy (ΔS°), also showed that the adsorption process was feasible and spontaneous.","PeriodicalId":322389,"journal":{"name":"International Journal of Chemistry Research","volume":"63 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140794650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is an indispensable tool in computer-aided drug design and structural molecular biology. Using this technology, large libraries of compounds may be digitally screened, and the results can be graded along with structural assumptions about how the ligands impact the target's reduction. Recent advances in the synthesis of anti-infectious medicines prompted by structural insights have enabled the application of computer-assisted drug design in the quest for innovative mechanism-or structure-based drugs. Molecular docking is an important phase in the drug development process because it determines the best positions for molecules to occupy when they are coupled together and predicts how effectively two molecules will bind once they have been docked. The input structure's design is also critical, and the results are assessed using sampling methods and scoring systems. The recently developed docking software Local Move Monte Carlo provides a strong choice for customizable receptor docking strategies. Docking is a technique for determining how ligands and proteins interact. It is structurally sound and compatible with computer-assisted medication design. Successful docking discovers high-dimensional spaces and ranks function utilisation, resulting in a candidate docking rating that is acceptable. It may also be used to screen vast libraries of molecules and offer structural hypotheses for the process.","PeriodicalId":322389,"journal":{"name":"International Journal of Chemistry Research","volume":"6 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139457100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of heavy metals and dyes in water bodies are deadly to the living organisms inside water, in which these pollutants are bio-accumulated and biomagnified in the environment. Due to the health effects of these pollutants, it is, therefore, necessary to treat metal and dye-contaminated wastewater prior to its discharge into the environment in order to comply with the stringent environmental regulations and also safeguard the present and future generations. Methods: The influence of pH, contact time, initial metal concentration, adsorbent dosage and temperature were studied in batch experiments at room temperature and were measured using UV-VIS Spectrophotometer at wavelength 464 nm. Fourier Transform Infrared (FTIR) technique was employed as an instrument for characterization of the adsorbent before and after adsorption and the data were collected and interpreted using Microsoft Excel, 2016. Results: Maximum sorption for methyl orange was found to be at pH 2. The adsorption was rapid at the first 90 min of contact, with uptake of more than 90%, and equilibrium was achieved in 60 min of agitation. Langmuir, Freundlich and BET’s isotherm models were applied to describe the adsorption of methyl orange dye. Fourier Transform Infrared (FTIR) spectra of ceramics powder revealed that OH, C-H, C=C, C-O stretching were responsible for the adsorption. However, the effects of different experimental parameters that influenced the efficiencies of the adsorbent have been evaluated and optimized. Conclusion: The investigation revealed that the adsorption capacity of the powdered ceramics on the removal of methyl orange dye is high enough compared to observed values in literatures. Freundlich’s model fitted the equilibrium data better, while the pseudo-second-order kinetic model was the most fitting from the kinetic data obtained for the adsorption of methyl orange dye.","PeriodicalId":322389,"journal":{"name":"International Journal of Chemistry Research","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134934208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The working standard solution for each component was accurately placed into a series of 10 ml calibrated volumetric flasks, then 1 ml of the ninhydrin reagent was added and heated in a water bath for 15 min. The wavelength(s) of maximum absorption(s) was recorded after scanning the resultant purple complex from 350 nm to 930 nm. The final working concentrations ranged between 1600 and 2000 ug/ml.\u0000Results: The average weight of a neomycin sulphate tablet was 0.747g, with a standard deviation of 0.667%.
