This article emphasizes the drug repurposing of 9H-thioxanthene based on FDA-approved drugs for anticancer agents precisely targeting VEGFR-2 and COX-2. The investigated 9H-thioxanthene drugs 1-4 were analyzed for Lipinski's drug-likeness rule and ideal ADME parameters. The results show that all calculated physicochemical descriptors and pharmacokinetic properties are within the expected range. 9H-thioxanthene drugs 1-4 were subjected to molecular docking to determine their molecular interactions at the active sites of VEGFR-2 and COX-2. The molecular docking study revealed that all four 9H-thioxanthene drugs 1-4 were able to target VEGFR-2 and COX-2. In the future, these findings will be greatly favorable in augmenting the utility of the development of the investigated drugs 1-4 for cancer therapeutics specifically targeting VEGFR-2 and COX-2.","PeriodicalId":9026,"journal":{"name":"Biointerface Research in Applied Chemistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48102580","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}

Due to the exponential increase in nanomaterial diversity, production, and possibilities of applications in different areas, there is an important concern about its toxicity for humans, animals, and ecosystems. There is a great effort to minimize experimental assays in animals, and this is a commendable initiative. Several alternatives in vitro assays are available; however, several new protocols have been introduced to elucidate the mechanisms of cell-nanomaterial interaction. Wide and fast progress in nanotechnology has been observed. Nonetheless, the nanomaterial interaction with cells or biological systems is still not totally described.

According to analytical data, all complexes demonstrated a 1:1 metal-to-ligand ratio with an octahedral shape. Thermal analysis showed that the complexes have acceptable thermal stability. Cyclic voltammetry was also used to observe their redox actions, and it was found that all of the complexes had electrochemical activity. Using GAUSSIAN 09 W software, the density functional theory (DFT) method and the 3-21G basis set, optimized structures (HOMO & LUMO) of ruthenium complexes (1-4) were carried out. Additionally, the selected quantum and geometric parameters of bond lengths and angles have been determined. The antimicrobial activity of ligand and ruthenium complexes has been evaluated against bacteria (Escherichia coli, Staphylococcus aureus) and fungi (Candida albicans). Two human cancers, HePG-2(hepatocellular carcinoma) and MCF-7 (Michigan Cancer Foundation-7), were tested for cytotoxic activity of complexes. Using the ABTS technique, the antioxidant function of complexes was evaluated. Using a high-affinity Fab sandwich and a specific PCa antibody, molecular docking was utilized to anticipate how the ligand would bind to a human prostate-specific antigen (PSA) immune system receptor (3qum).","PeriodicalId":9026,"journal":{"name":"Biointerface Research in Applied Chemistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42915802","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}

Using the sol-gel method, the HA was incorporated into SA-Np at a weight ratio of 0.5 of HA to SiO2 (HA-SA-Np). The efficacy of HA-SA-Np, SA-Np, and HA on the in vitro migration of normal human dermal fibroblast cells (HSF1184) was compared. The cell migration was measured at 0, 6, and 24 hours after scratching using ImageJ and an inverted optical microscope. To ascertain the resorbability of HA-SA-Np, the phosphate and silicic acid concentrations in media treated for 2, 5, and 7 days were examined. The high dissolution of HA could be reduced by incorporating the HA into the silica nanosphere. The HA-SA-Np significantly stimulated cell migration and increased closure with increasing treatment time. It was caused by the release of silicic acid, which aided in healing cells. It also demonstrates the ability of HA-SA-Np to be resorbed and eventually increase the adhesion and migration of normal human fibroblast cells. As a result, the potential application of HA-SA-Np as an alternative biomaterial was confirmed.","PeriodicalId":9026,"journal":{"name":"Biointerface Research in Applied Chemistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49531849","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}

One of the most common isolated oral streptococci is Streptococcus mutans, which has a significant role in oral diseases, including periodontal. The most important factor of S. mutans pathogenesis includes biofilm formation that leads to emptying tooth enamel and caries. Various genes including atpF, gtfB, gtfC, gtfD, gtf, LuxS, comAB, comCDE, and comX regulate biofilm formation. Therefore, in this review, we aimed to investigate factors that influence S. mutans pathogenicity in the mouth. The main factors are related to the biofilm formation of this bacteria and metabolic products, which influence environmental changes by carbohydrate metabolism and help this pathogen to make dominant growth compared to other bacteria living in the oral cavity. Indeed, developing methods to inhibit biofilm formation and quorum sensing using antimicrobial agents with anti-biofilm and antibacterial properties should be considered based on our knowledge of the pathogenicity mechanisms of S.mutans.","PeriodicalId":9026,"journal":{"name":"Biointerface Research in Applied Chemistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43628947","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}

UV–Vis spectroscopy is used to obtain the samples' absorption spectrum and calculate the band gap energy. X-ray diffraction patterns and FT-IR investigations confirmed the formation of a single-phase M-type hexagonal structure. The grain size was measured from Scherrer's equation, and it is found in the range of 43-56 nm, with increasing the concentration of Mn ions, which shows the enhancement in the degree of crystallinity and increase in the size of grain size. UV-vis spectroscopy was used to confirm the formation of the BaZn1+x Mnx Fe12-2x O19 nanoparticles. The transmission was found to increase slowly in the 200-290 nm wavelength and then decreased to 332 nm after that increase until the maximum for all samples was about 99% in 480-800 nm wavelengths. The highest transmission will be exclusively used for window layers in solar cells. The band gap energy increased gradually with a rise in Mn ions and a decrease in Zn ion concentration.

GABAAR has been immunopurified from rat brain membranes on protein A agarose beads immobilized with complex anti-GABAAR antibody. Primary structure and post-translational modifications of the α1 subunit of GABAAR have been characterized by nano-LC-FTMS peptide mapping by direct in situ–gel digestion on the one-dimensional gel. The primary structure of the α1 subunit of GABAAR has been identified with high sequence coverage (81%, 371 from 455 amino acids).
