Combining Ultraviolet Photolysis with In-Situ Electrochemical Oxidation for Degrading Sulfonamides in Wastewater was written by Zheng, Zhijie;Yuan, Julin;Jiang, Xinwei;Han, Gang;Tao, Yufang;Wu, Xiaogang. And the article was included in Catalysts in 2022.Synthetic Route of C11H12N4O3S This article mentions the following:

UV photolysis (UVC, 254 nm) was coupled with an electrochem. oxidation process to degrade three kinds of veterinary sulfonamide (sulfamethazine [SMZ] tablets, sulfamonomethoxine [SMM] tablets, and compound sulfamethoxazole [SMX] tablets). The treatment was applied using a flat ceramic microfiltration membrane to study the effects of photocatalysts. The effectiveness of degradation of the three sulfonamides was evaluated under different conditions. Dissolved oxygen was provided via aeration, but this resulted in a large decrease in the degradation effectiveness due to the inhibition of free chlorine electrogeneration. The photocatalysts had no promotional effect on sulfonamide removal from wastewater due to reduced UV penetration. Because of the different distribution coefficients of sulfonamides, UV irradiation had different effects on different sulfonamide species. For SMZ and SMM, anionic species exhibited a higher degradation rate, whereas for SMX, degradation was most effective for neutral species. In addition, the free chlorine yield increased as the pH increased. Free chlorine conversion reactions occurred under UV irradiation, with the reactions possibly restrained by sulfonamides. Reactive chlorine species promoted SMM degradation Compared to UV irradiation or electrochem. oxidation alone, the UV/in-situ electrochem. oxidation process was more effective and is suitable for treating real wastewater under various environmental pH levels. In the experiment, the researchers used many compounds, for example, 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3Synthetic Route of C11H12N4O3S).

The source apportionment of pharmaceuticals and personal care products (PPCPs) in the water environment based on indicators (i-PPCPs) requires a comprehensive characterization of various emission sources using reliable anal. methods for a wide spectrum of PPCPs. In this study, a robust and sensitive method based on solid phase extraction (SPE) and ultra-high performance liquid chromatog. coupled with tandem mass spectrometry (UHPLC-MS/MS) for analyzing 70 PPCPs belonging to 17 therapeutic classes in landfill leachates and livestock wastewaters was developed. The SPE cartridges, sample pH, elution solvents and chelating agent additions were optimized, and acceptable recoveries (60- 130% for 67 target compounds), low method quantification limits (landfill leachate: 3- 1309 ng/L; livestock wastewater: 3- 686 ng/L) and high precisions (repeatability: 0- 20% for over 99% injections; reproducibility: 0- 20% for over 90% injections) were obtained. Using the optimized anal. method to characterize PPCPs in the typical landfill leachate and livestock wastewater in Yangtze River Delta, China, we found anthelmintics, which were first reported in landfill leachates globally, exhibited the highest concentration (albendazole, maximum concentration of 61.6娓璯/L), and therefore proposed albendazole as one of the promising i-PPCP candidates in landfill leachates. In the experiment, the researchers used many compounds, for example, 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3COA of Formula: C11H12N4O3S).

Disrupting Transcription and Folate Biosynthesis Leads to Synergistic Suppression of Escherichia coli Growth was written by Chen, Pei-Hsin;Sung, Li-Kang;Hegemann, Julian D.;Chu, John. And the article was included in ChemMedChem in 2022.Application In Synthesis of 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide This article mentions the following:

The use of synergistic antibiotic combinations has emerged as a viable approach to contain the rapid spread of antibiotic-resistant pathogens. Here we report the discovery of a new strongly synergistic pair – microcin J25 and sulfamonomethoxine. The former is a lasso peptide that inhibits the function of RNA polymerase and the latter is a sulfonamide antibacterial agent that disrupts the folate pathway. Key to our discovery was a screening strategy that focuses on an antibiotic (microcin J25) that targets a hub (transcription) in the densely interconnected network of cellular pathways. The rationale was that disrupting such a hub likely weakens the entire network, generating weak links that potentiate the growth inhibitory effect of other antibiotics. We found that MccJ25 potentiates five other antibiotics as well. These results showcase the merit of taking a more targeted approach in the search and study of synergistic antibiotic pairs. In the experiment, the researchers used many compounds, for example, 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3Application In Synthesis of 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide).

Risk assessment and investigation of landfill leachate as a source of emerging organic contaminants to the surrounding environment: a case study of the largest landfill in Jinan City, China was written by Wang, Kun;Reguyal, Febelyn;Zhuang, Tao. And the article was included in Environmental Science and Pollution Research in 2021.Synthetic Route of C11H12N4O3S This article mentions the following:

Emerging organic contaminants (EOCs) have been widely studied in landfill leachates but not in the surrounding environment of landfills. In this study, two sampling campaigns were conducted to determine 45 EOCs in landfill leachates and environmental samples near a landfill in East China. Our study focused on the seasonal occurrence and spatial distribution of the target EOCs, as well as their ecol. risks. The results showed 13 out of 45 EOCs were detectable and achieved individual concentrations that ranged from 2.0 to 5080 ng/L in the landfill leachates. Most of the detected EOCs exhibited higher concentrations in the leachates collected in summer than in winter. The contamination levels of the target EOCs in groundwater decreased with the distance of sampling sites from the landfill. In soil samples, the occurrence of target EOCs was not consistent with raw or treated landfill leachates. Risk assessment suggested that the individual EOC likely posed medium to high risks to aquatic organisms in groundwater while negligible impacts to human health through consumption of vegetables. To the best of our knowledge, this is the first report on the contribution of landfill leachates to EOC contamination in both aquatic and soil environments in East China. Our findings emphasized the importance of investigating EOCs in landfill leachates and accumulative environmental risks of EOCs in the neighboring environment of landfills in China.

Occurrence of antibiotics in the different biological treatment processes, reclaimed wastewater treatment plants and effluent-irrigated soils was written by Pu, Miao;Ailijiang, Nuerla;Mamat, Anwar;Chang, Jiali;Zhang, Qiongfang;Liu, Yifan;Li, Nanxin. And the article was included in Journal of Environmental Chemical Engineering in 2022.Safety of 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide This article mentions the following:

Reclaimed wastewater is increasingly being used for agricultural irrigation to address water scarcity, particularly in arid and semiarid areas. In this study, the occurrence and removal of 24 antibiotics were investigated in two wastewater treatment systems (WWTSs) and their irrigation areas located in the arid northwestern region of China. The different WWTSs included absorption-biodegradation (AB) + anaerobic-anoxic-oxic (AAO) and AAO + AAO + membrane bioreactor (MBR). Nineteen antibiotics were detected, with concentrations ranging from low to 60.8娓璯/L. The dominant antibiotic classes were quinolones (QNs) and macrolides (MLs) in winter, and MLs and sulfonamides (SAs) in summer. The AAO + AAO + MBR system exhibited better removal efficiencies for most antibiotics, improving their adsorption and biodegradation Except for ofloxacin (OFC) and norfloxacin (NFC), the concentrations of the detected antibiotics were higher in summer than in winter. However, the antibiotic removal efficiency increased by 2-141% in summer compared to winter due to the increase in microbial activity with temperature Even though reclaimed treatment water plants contributed to the removal of antibiotics, residual antibiotics still affected the soil environment after green irrigation. In irrigated soil, QNs were predominantly detected, with a maximum concentration of 150.9 ng/kg for NFC. An ecol. risk assessment showed that OFC, NFC, enrofloxacin, and lomefloxacin presented low or medium ecol. risks in at least two irrigated sites. Thus, more attention should be given to the reuse of reclaimed wastewater, as it may pose toxicity risks to organisms in the soil environment.

Transformation of food waste to source of antimicrobial proteins by black soldier fly larvae for defense against marine Vibrio parahaemolyticus was written by Zhang, Shouyu;Xiong, Pu;Ma, Yongsheng;Jin, Ning;Sun, Shibo;Dong, Xiaoying;Li, Xiaodong;Xu, Jianqiang;Zhou, Hao;Xu, Weiping. And the article was included in Science of the Total Environment in 2022.Reference of 1220-83-3 This article mentions the following:

Insect biorefinery by black soldier fly larvae (BSFL), Hermetia illucens, has emerged as an innovative technique for the valorization of food waste. However, despite BSFL being an attractive natural source of antimicrobial proteins (AMPs), there is a scarcity of research on the antimicrobial activity and transcriptome expression of AMPs derived from BSFL following waste treatment. In the present study, food waste treatment was performed by BSFL with a substrate C/N ratio ranging from 21:1 to 10:1, marine Vibrio parahaemolyticus (VP) was selected as the model aquaculture pathogen, the antimicrobial activities of AMPs in vitro and zebrafish in vivo were examined, and the mol. mechanism of the C/N-dependent AMP difference was expounded. Findings were made that the AMP extract of C/N16:1 resulted in relatively higher antimicrobial activity in vitro than that of other C/Ns. Further, the AMPs of C/N16:1 exhibited a promising in vivo defense effect for elevating the 96-h survival rate of zebrafish from 0% to 39% after VP infection, comparable to the animal antibiotic sulfamethoxidine. The results of transcriptome anal. reveal that lysozymes were the highest expressed components in the AMP gene family. The C/N16:1 BSFL significantly up-regulated 12 out of 51 lysozyme genes compared with C/N21:1, which likely contributed to the improvement of AMP antimicrobial activity. Further, C/N16:1 significantly up-regulated the expression of lysozyme, glycosyl hydrolase and muscle protein genes compared with C/N21:1, which likely enhanced the defense ability of the immune system, the utilization of the starch-like substrate, and the mobility of the larvae, thereby facilitating the larval transformation and AMP production Overall, such results indicate that waste C/N ratio interacted with the activity and expression of BSFL AMPs through transcriptome regulation, and the BSFL AMPs derived from food waste could be used for the defense against marine pathogens to support the sustainable development of aquaculture.

Dynamics of antibiotics and antibiotic resistance genes in four types of kitchen waste composting processes was written by Zhao, Changxun;Xin, Liqing;Xu, Xingkun;Qin, Yong;Wu, Weixiang. And the article was included in Journal of Hazardous Materials in 2022.Recommanded Product: 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide This article mentions the following:

Kitchen waste might be a potential source of antibiotics and antibiotic resistance genes. Composting is recognized as an effective way for kitchen waste disposal. However, the effects of different kitchen waste composting types on the removal of antibiotics and antibiotic resistance genes haven’t been systematically studied. In this study, the dynamics of antibiotics and antibiotic resistance genes from kitchen waste of four composting processes were compared. Showed that although kitchen waste was composted, it remained an underestimated source of antibiotics (25.9-207.3娓璯/kg dry weight) and antibiotic resistance genes (1012-1017 copies/kg dry weight). Dynamic composting processes (i.e., dynamic pile composting and mech. composting) decreased the antibiotic removal efficiency and increased the abundance of some antibiotic resistance genes (5.35-8534.7% enrichment). Partial least-squares path model anal. showed that mobile genetic elements played a dominant role in driving antibiotic resistance genes dynamics. Furthermore, redundancy anal. revealed that temperature, pH, and water content considerably affected the removal of antibiotics and mobile genetic elements. This study provides further insights into exploring the effective strategies in minimizing the risk of antibiotic resistance from kitchen waste via composting process.

Seasonal occurrence of multiple classes of antibiotics in East China rivers and their association with suspended particulate matter was written by Wang, Kun;Su, Zhaoxin;Reguyal, Febelyn;Bian, Rongxing;Li, Weihua;Yu, Haofeng;Sun, Yingjie;Zhuang, Ying;Shang, Wan. And the article was included in Science of the Total Environment in 2022.Synthetic Route of C11H12N4O3S This article mentions the following:

Understanding the occurrence and fate of antibiotics from different categories is vital to predict their environmental exposure and risks. This study presents the spatiotemporal occurrence of 45 multi-class antibiotics and their associations with suspended particulate matter (SPM) in Xiaoqing River (XRB) and Yellow River (YRB) via 10-mo monitoring in East China. Thirty-five and 31 antibiotics were detected in XRB and YRB, resp. Among them, fluoroquinolones (FQs) had the highest total mean concentration (up to 24.8娓璯/L in XRB and 15.4娓璯/L in YRB), followed by sulfonamides (SAs) (14.0娓璯/L and 15.4娓璯/L) and macrolides (MLs) (1.1娓璯/L and 1.6娓璯/L). Significant spatial-temporal variations were found in both rivers where higher concentrations of antibiotics were observed in urban and densely populated areas during winter and spring. Hydrol. factors such as river flow and water volume, instream attenuation and antibiotic usage may cause the observed variabilities in the seasonal patterns of antibiotic pollution. Using linear regression anal., for the first time, this study confirmed that the total concentrations of MLs (p < 0.05), FQs (p < 0.001) and SAs (p < 0.001) were strongly correlated with the turbidity/total suspended solids in the studied rivers (except MLs in YRB). It is thus suggested that partitioning processes onto SPM might affect the distribution of detected antibiotics in rivers, which are largely dependent on SPM composition and characteristics. The risk quotient (RQ) determined for up to 87% of individual compound was below 0.1 in both rivers; however, the high joint toxicity reflected by the mixed RQs of detected antibiotics may rise risk alarm for aquatic species. Further aspects regarding active mechanisms of SPM-antibiotic interactions and ecol. risks of coexistence of multiple antibiotics need to be investigated.

Global retention models and their application to the prediction of chromatographic fingerprints was written by Gisbert-Alonso, A.;Navarro-Huerta, J. A.;Torres-Lapasio, J. R.;Garcia-Alvarez-Coque, M. C.. And the article was included in Journal of Chromatography A in 2021.Quality Control of 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide This article mentions the following:

The resolution of samples containing unknown compounds of different nature, or without standards available, as is the case of chromatog. fingerprints, is still a challenge. Possibly, the most problematic aspect that prevents systematic method development is finding models that describe without bias the retention behavior of the compounds in the samples. In this work, the use of global models (able to describe the whole sample) is proposed as an alternative to the use of individual models for each solute. Global models contain parameters that are specific for each solute, while other parameters -related to the column and solvent- are common for all solutes. A special regression procedure is presented for the construction of global models, which are applied to predict highly complex chromatograms, such as chromatog. fingerprints, for diverse exptl. conditions in isocratic and gradient elution. Another interesting application is the prediction of mol. properties, such as log P_o/w, from the specific solute parameters of the global models. The examined adapted models are based on the equations proposed by Snyder, Schoenmakers, Neue and Kuss, Jandera, and Bosch Rose鑹?to describe the retention. In all cases, the predictive capability was very satisfactory. Two cases of study were considered: chromatograms of chamomile extracts analyzed using acetonitrile gradients, and a set of 145 known compounds in a wide range of structures and functionalities, eluted isocratically with acetonitrile/water mobile phases.

Determination and occurrence of sulfonamide transformation products in surface waters was written by Cui, Hongyang;Chang, Hong;Zheng, Hongjin;Wan, Yi. And the article was included in Science of the Total Environment in 2021.Reference of 1220-83-3 This article mentions the following:

The transformation products of sulfonamides (SAs) have raised increasing environmental and health concerns in recent years, but information on their anal. and environmental fates remains limited. In this study, an anal. method using liquid chromatog. with tandem mass spectrometry (LC-MSMS) was optimized to simultaneously analyze 9 SA transformation products and 14 SAs in water samples. This method was applied to investigate the occurrence of antibiotics in three urban rivers in Beijing, and all of the target compounds were detected. N-acetylsulfamethoxazole, N-acetylsulfapyridine, and N-acetylsulfamethazine were found to be the predominant acetyl SAs in the aquatic environment, and high frequencies of hydroxylated SA (5-hydroxysulfapyridine) and glucuronide-conjugated SA (sulfamethoxazole 灏?D-glucuronide) were also detected. The SA transformation products accounted for 22-32% of the total concentrations of SAs and their transformation products in the water samples. The pollution levels of the compounds exerted only minor effects on the proportions of the SA transformation products. The compound-specific transformation of sulfamethoxazole, sulfapyridine, and sulfadiazine in the water samples was consistent with their acetylation efficiencies in metabolic processes in organisms, which suggests that the SA-acetylated products were derived mainly from biol. metabolism in humans or animals. This finding was supported by the fact that environmental degradation exerts a weak effect on SA profiles in the water samples. In the experiment, the researchers used many compounds, for example, 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3Reference of 1220-83-3).
