These improvements include new dyes, such as Black Dye N749 (BD), one of the most used synthetic dyes. A comparative analysis of the current output profiles of cells based on cochineal and black dye is reported. It was observed that BD has to be catalyzed to produce a high output current: by itself, this dye showed low output currents, but when it is catalyzed, its performance significantly improves. Cochineal shows, when used alone, a high output current. Different additives were tested: Alum and Sn as a mordant and mineral carbon as a catalyst, which contains ions of Fe²⁺ and Fe³⁺; these significantly modify the shape (rising or decreasing) and intensity of the output current profiles. Unstable oscillations appear in the current profile when the cell is abruptly illuminated; a model was included to fit the experimental data.</div></div>","PeriodicalId":420,"journal":{"name":"Results in Chemistry","volume":"12 ","pages":"Article 101913"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142742889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morphological and chemical characterizations of the sensor surface were studied by FT-IR, UV-visible Spectrophotometry, and SEM. The electrochemical behavior of the sensor and the oxidation behavior of BPA at the MnPc-His-CPE/BPA interface were investigated by cyclic voltammetry (CV), chronocoulometry (CC), square wave voltammetry (SWV), and electrochemical impedance spectroscopy (EIS). Square wave voltammetry (SWV), applied as a sensitive analytical method for BPA determination, led to a good linear correlation between BPA concentration and peak current in the range from 2.10⁻⁸ mol.L⁻¹ to 5.10⁻⁵ mol.L⁻¹ and a detection limit of 4.63 nM (S/N = 3). The relative standard deviation was 4.10 % (n = 10). The proposed sensor was found to be highly selective for BPA.

Our previous study showed that HCA induced reactive oxygen species (ROS) and apoptosis in cancer cells, and pretreatment of cancer cells with antioxidants abolished HCA-mediated ROS production and apoptosis. This indicates that ROS are critical effector for HCA activity. However, the molecular target of HCA for ROS induction has not been identified. In the present study, we identified peroxiredoxin 1 (PRX1) and peroxiredoxin 2 (PRX2) as target proteins of HCA using affinity chromatography, and further confirmed these association using a cellular thermal shift assay (CETSA). In addition, we used mutagenesis to identify important cysteine residues in PRX1 for HCA binding. PRX1 has four cysteines (Cys52, Cys71, Cys83, and Cys173), and when Cys173 (but not the other cysteine sites) was mutated to serine, it was unable to bind biotin-conjugated HCA, suggesting that Cys173 is important for HCA binding. Treatment of SW620 cancer cells transfected by control vector with 20 μM HCA increased ROS levels by 5.2-fold compared to DMSO-treated cells. However, downregulation of target proteins PRX1 and PRX2 using shRNAs (short hairpin RNA) significantly reduced HCA-mediated ROS induction (1.6-fold), supporting that PRX1 and PRX2 are targets of HCA for ROS elevation. Additionally, intraperitoneal injection of 50 mg/kg HCA inhibited SW620 tumor growth, resulting in a 59.9 % reduction in tumor volume. CETSA analysis of tumor tissues showed that PRX1 and PRX2 were bound and thus inactivated by HCA in a mouse xenograft model.
