Malachite green (MG) was selected as a model dye representing those pollutant chemicals. The catalyst was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS). Malachite green (MG) decolorization was carried out by visible light irradiation of a 105 W tungsten light source. Decolorization yield and kinetic studies were traced by the help of a UV-Vis spectrophotometer. Kinetic model of decolorization was derived from Langmuir–Hinshelwood (L–H) model and found coherent to first order kinetics. Catalysis reaction showed high dependency on pH especially out of 5-7 range which gave high decolorization. Photocatalytic activity also depended on concentration with dual character in which high concentration hindered the light coming to catalyst surface but on the other hand it supported the activity by boosting the dark adsorption resulting in a decolorization time changing from 40 to 100 min. After the reaction was completed, powders of catalyst were effortlessly removed from the medium by a magnet bar. It was shown that MgFe 2 O 4 -B/Ag 3 VO 4 photocatalyst has a potential to be simple and efficient alternative material for the removal pollution resources from wastewaters.","PeriodicalId":17402,"journal":{"name":"Journal of the Turkish Chemical Society, Section A: Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41765744","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}

Based on this fact and our doubts regarding the quality of the river waters of the Municipality of Gjilan, we were motivated to conduct a study of the quality of the Mirusha, Stanishor and Morava river waters. During our research, we have set eight monitoring points for determining the exact level of concentration of heavy metals in the river waters quoted above. The heavy metals analyzed in this study were: Pb, Hg, Mn, Cu, Fe, Ni, Cr, Cd, Zn and Ba. The analytical technique used to determine the concentration of heavy metals was ICP-OES. The obtained results show that Fe, Mn and Ba exceed the allowed level at several monitoring points of the Mirusha and Stanishor rivers and appears in the degree of pollution with these metals of Morava river waters. The presence of heavy metals in the waters of these rivers negatively affects habitat waters and indirectly human health. Therefore, the identification and then suggestions regarding elimination of polluting sources are the subject of this study.","PeriodicalId":17402,"journal":{"name":"Journal of the Turkish Chemical Society, Section A: Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41501250","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}

Structures of topoisomerase–DNA and inhibitor ternary complexes have revealed the exact binding sites and mechanisms of topoisomerase poisons. There are two isoforms of Human Topoisomerase II; α and β. Both of them perform similar functions and their levels differ depending on the replicative activity and type of tissue. Topo IIα is preferentially expressed in proliferating cells. Thus selective Topo IIα inhibitors have been of particular interest in cancer therapy, as they may represent a more targeted approach to highly proliferative cells. In this study, we use structure based virtual screening method with molecules which are commercially available in the ZINC database. Docking studies were performed by Glide module available in Schrodinger software, Ligand filtration was also done to obtain an efficient collection of hit molecules by employing Lipinski “rule of five” and pharmacokinetic properties of the compounds were tested using Qikprop module. From approximately ten thousand compounds from Zinc database it was possible to select 4 top chemical structures with good inhibiting profile for topo II, with suitable ADME/Tox properties, thus comp. 1-4 could be the promising inhibitors of human topo IIα enzyme.","PeriodicalId":17402,"journal":{"name":"Journal of the Turkish Chemical Society, Section A: Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49567362","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}
