Plant effluents have different compositions and concentrations of pollutants, depending on the kind of production and the water supply and sewerage system. The main sources of phenol-containing wastewater are coking plants, coke oven gas plants, semi-coking plants, gas generating stations, wood heat treatment plants, and the synthesis of artificial liquid fuels. They can also be the result of the activities of metallurgical plants, oil refineries, enterprises for the recovery of rubber, and the production of film, phenolphthalein, salicylic acid, and salol. Phenolic waters are dangerous for fishery reservoirs, worsen the organoleptic properties of water, and disrupt the natural processes of water self-purification. Water contaminated with phenolic wastewater contributes to the deterioration of groundwater quality. Thus, high-quality water purification from phenol to reduce/maximum prevent the ingress of phenols into industrial and drinking water is an urgent problem. Methods for deep treatment of phenolic wastewater are regenerative and destructive. The technology for purifying phenolic wastewater using the processes of oxidation of phenolic compounds with atmospheric oxygen on heterogeneous catalysts is one of the most promising technologies. Nanodisperse catalysts used to treat wastewater containing aromatic hydrocarbons and, in particular, phenolic compounds, should provide a high rate of oxidation of phenolic pollutants, efficient oxidation of a wide range of compounds with various functional groups, low cost, and long service life without a noticeable loss of catalytic properties, as well as high mechanical strength and immunity to catalytic poisons. Catalysts based on various metals and metal oxides and carrier-based systems, oxide-based magnetic composites show good efficiency in the oxidation of phenol with oxygen.","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135595646","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}

In the current investigation, the inhibitory effect of biflavonoids extracted from Araucaria hunsteinii K. Schum towards the target protein α-glucosidase was assessed using a combination of in-vitro experiments and in-silico molecular docking approach. The biflavonoids' inhibition properties were contrasted with those of acarbose, a widely used pharmaceutical for treating type 2 DM. AutoDock Vina was employed to analyze the conformational sites and docking parameters, such as binding affinity and inhibition constant. In-silico studies showed that biflavonoids effectively interacted with the active site of the α-glucosidase enzyme, which is in charge of cleaving not only bonding of the α1,4 but also the α-1,6 glycosidic on the exterior of amylose or amylopectin residues to obtain simple sugars. The docking experiments revealed that biflavonoids had tighter binding forces than acarbose against α-glucosidase. The selected biflavonoids, 7-O-methylcupressuflavone; 7,7\"-di-O-methylagathisflavone, 4′,4′′′-di-O-methylamentoflavone and 4''',7-di-O-methylcupresuflavone showed an IC50 of 78.32±0.52; 388.39±0.68; 389.76±1.55 and 537.98±2,35 µM, respectively. These biflavonoids had a low binding affinity and more hydrogen bond interactions with the target enzyme, which had several important amino acid residues. The effectiveness of these compounds in inhibiting the enzyme may be explained by some of their hydrophobic interactions. Therefore, the study comes to the conclusion that biflavonoids are prospective antidiabetic agents and should be taken into consideration when developing candidates for new antidiabetic medicines.","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69410998","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}
