Antibiotic and heavy metal commonly coexist in manure. This study investigated the effect of Cu exposure on antibiotic dissipation in swine manure under two typical temperature (mesophilic and thermophilic) conditions in composting, focusing on biodegradation behaviors. The results showed that Cu promoted the dissipation of norfloxacin and sulfamethazine (SMZ) in solid swine manure under mesophilic conditions at initial concentrations ranging from 407.8 to 1353.0 mg·kg-1 but insignificantly influenced or even inhibited their dissipation under thermophilic conditions. A liquid manure suspension culture experiment was designed to elucidate the response of SMZ biodegradation to Cu. In this manure suspension, biodegradation was the major mechanism for SMZ removal, but SMZ biodegradation was decreased from 23.2% to 5.5% when the Cu concentration increased from 0 to 10 mg L^-1. Mesophilic and heat-resistant SMZ-degrading bacterial inoculants were subsequently prepared using 21 SMZ-degrading bacteria that were isolated and identified from manure suspension cultures. Inoculating both mesophilic and heat-resistant SMZ-degrading bacterial inoculants enhanced SMZ degradation in sterilized manure suspensions without Cu addition, however only mesophilic SMZ-degrading inoculum improved SMZ degradation after Cu addition In the presence of Cu, the heat-resistant SMZ-degrading inoculum failed to enhance SMZ removal in manure suspensions. Our findings can help to answer why Cu has varied effects on antibiotic degradation during manure composting. This study involved multiple reactions and reactants, such as 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7Synthetic Route of C16H18FN3O3).

1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7) belongs to piperazine derivatives. Piperazine was first introduced as an anthelmintic in 1953. Piperazine compounds mediate their anthelmintic action by generally paralyzing parasites, allowing the host body to easily remove or expel the invading organism. Outside the body, piperazine has a remarkable power to dissolve uric acid and producing a soluble urate, but in clinical experience it has not proved equally successful.

Surface water environment is an important repository of antibiotics and antibiotic resistance genes (ARGs). It is of great significance to study the occurrence and distribution of antibiotics and ARGs in surface water environment. In this study, the Liaohe River Basin, China was taken as the study area, and the concentrations of antibiotics and ARGs in water were investigated by HPLC-MS/MS and HT-qPCR. The results showed that a total of 53 antibiotics of 6 types were detected in water, and the pollution level was at ND∼331.64 ng/L, where PCG was the highest. Totally 164 ARGs and 10 mobile genetic elements (MGEs) were detected in the water, and the absolute abundances were at 2.18 × 10⁴∼3.95 × 10⁷ copies/L and 1.82 × 10⁵-3.78 × 10⁷ copies/L, resp. The multidrug and aminoglycoside were the dominant ARG types. Amoxicillin, erythromycin, anhydroerythromycin and ofloxacin posed certain ecol. risks for sensitive aquatic organisms. In spatial distribution, the pollution of antibiotics and ARGs in the Daliao River system was higher than that in the Liaohe River system. There was a significant pos. correlation between total concentrations of antibiotics and total relative abundance of ARGs (r = 0.66, p < 0.05). The co-occurrence of multiple antibiotics promoted the pollution and spread of ARGs. In addition, the total relative abundance of MGEs and ARGs showed a significant pos. correlation (r = 0.946, p < 0.01), and MGEs played an important role in the occurrence and evolution of ARGs in water.

Testing the stability of drug resistance on cryopreserved, gene-engineered human induced pluripotent stem cells was written by Khan, Dilaware;Nickel, Ann-Christin;Jeising, Sebastian;Uhlmann, Constanze;Muhammad, Sajjad;Haenggi, Daniel;Fischer, Igor;Kahlert, Ulf Dietrich.

Human induced pluripotent stem cells (hiPSCs) have emerged as a powerful tool for in vitro modeling of diseases with broad application in drug development or toxicol. testing. These assays usually require large quantities of hiPSC, which can entail long-term storage via cryopreservation of the same cell charges. However, it is essential that cryopreservation does not oppose durable changes on the cells. In this project, we characterize one parameter of functionality of one that is well established in the field, in a different research context, an applied hiPSC line (iPS11), namely their resistance to a medium size library of chemo interventions (>160 drugs). We demonstrate that cells, before and after cryopreservation, do not change their relative overall drug response phenotypes, as defined by identification of the top 20 interventions causing dose-dependent reduction of cell growth. Importantly, also frozen cells that are exogenously enforced for stable overexpression of oncogenes myelocytomatosis (cMYC) or tumor protein 53 mutation (TP53R175H), resp., are not changed in their relative top 20 drugs response compared to their non-frozen counterparts. Taken together, our results support iPSCs as a reliable in vitro platform for in vitro pharmacol., further raising hopes that this technol. supports biomarker-associated drug development. Given the general debate on ethical and economic problems associated with the reproducibly crisis in biomedicine, our results may be of interest to a wider audience beyond stem cell research.

And the article was included in European Journal of Pharmaceutical Sciences in 2021.Computed Properties of C33H39N5O7S The following contents are mentioned in the article:

The present research work was aimed to explore the ability of nanostructured lipid carriers (NLCs) to improve oral bioavailability of Nintedanib esylate (NE) via lymphatic uptake. The NE loaded NLCs (NE-NLCs) were fabricated using high speed homogenization followed by probe sonication method and physiochem. characterized. The NE-NLCs had particle size of 125.7 ± 5.5 nm, entrapment efficiency of 88.5 ± 2.5% and zeta potential of -17.3 ± 3.5 mV. DSC and XRD studies indicated that NE was converted to amorphous form. TEM images showed uniformly distributed spherical shaped particles. In vitro release study of NE-NLCs showed drug release of 6.87 ± 2.72% in pH 1.2 and 92.72 ± 3.40% in phosphate buffer pH 6.8 and obeyed higuchi model. Lipolysis study showed higher amount of drug in aqueous layer in NE-NLCs compared to NE-suspension. Tissue distribution study showed deeper penetration of FITC loaded NLCs compared to FITC solution The cellular uptake across Caco-2 cells exhibited more uptake of FITC loaded NLCs. Cytotoxicity study using A549 cell line revealed higher potential of NE-NLCs in inhibiting tumor cell growth in comparison to that of suspension. The oral bioavailability of NE was ameliorated over 26.31 folds after inclusion into NLCs in contrast to NE-suspension. Intestinal lymphatic uptake of NE-NLCs in cycloheximide treated mice was lower as compared to control without cycloheximide treatment. Thus, the developed NE-NLCs can be an encouraging delivery strategy for increasing oral bioavailability of NE via lymphatic uptake.

An efficient molecularly imprinted polymer (MIP) voltammetric sensor was prepared based on polypyrrole (PPy) imprinted film-bearing poly(3,4-ethylenedioxythiophene):polystyrene sulfonate-functionalized black phosphorene (BP-PEDOT:PSS) for the selective recognition and robust determination of norfloxacin. BP-PEDOT:PSS was prepared via a simple ultrasonic-assisted liquid-phase exfoliation as an efficient support for use in MIP electrochem. sensors. The imprinted PPy film was deposited onto the surface of BP-PEDOT:PSS via the potentiodynamic technique in the presence of norfloxacin, with the imprinting factor of 3.86 for norfloxacin. The morphologies and microstructures of the sensing materials were investigated using SEM, energy dispersive X-ray spectroscopy, transmission electron microscopy, and Raman spectroscopy. Addnl., parameters including the BP-PEDOT:PSS loading volume, norfloxacin:pyrrole molar ratio, electropolymerization cycles, template removal, solution pH, and time of electrode exposure to the analyte were optimized. Under optimal conditions, the response peak currents of norfloxacin correlated linearly to norfloxacin concentrations from 0.001 to 10μM, with a limit of detection of 0.25 nM. The prepared imprinted sensor could effectively distinguish norfloxacin from other fluoroquinolone antibiotics with the selectivity coefficients of 5.4-17.3 and maintained stable, robust voltammetric responses for up to two weeks.

A novel S-scheme heterojunction of Cd_0.5Zn_0.5S/BiOCl with oxygen defects for antibiotic norfloxacin photodegradation: Performance, mechanism, and intermediates toxicity evaluation was written by Cai, Mingjie;Liu, Yanping;Dong, Kexin;Wang, Chunchun;Li, Shijie. And the article was included in Journal of Colloid and Interface Science in 2023.Product Details of 70458-96-7 The following contents are mentioned in the article:

S-scheme heterojunction structure can endow the photocatalysts with high-performance photo-degradation of pharmaceuticals and personal care products (PPCPs) since it can remain the photogenerated electrons/holes with stronger redox ability. Herein, an integrative S-scheme heterojunction photocatalyst building from Cd_0.5Zn_0.5S nanoparticles and BiOCl microflowers with oxygen vacancies (OVs) was developed. Moreover, the in-situ grown process ensures the firm contact and intense electron coupling between BiOCl and Cd_0.5Zn_0.5S. As a result, Cd_0.5Zn_0.5S/BiOCl exhibited a significant reinforcement of photo-activity and stability for the abatement of antibiotic norfloxacin, manifesting a 2.8-fold or 9.6-fold enhancement compared to pristine Cd_0.5Zn_0.5S or BiOCl. Cd_0.5Zn_0.5S/BiOCl also shows good resistance to alk., sodium salts and humic acid. The performance of Cd_0.5Zn_0.5S/BiOCl to photocatalytically degrade other PPCPs with different mol. structures was further confirmed. At last, the ability of Cd_0.5Zn_0.5S/BiOCl for PPCPs de-toxicity was verified by evaluating the toxicity of norfloxacin and its degradation intermediate.

Abstract: Nintedanib esylate is a kinase inhibitor designated for the cure of non-small cell lung cancer suffered from first-pass metabolism which resulted in low oral bioavailability (∼ 4.7). The exploration intended to increase the oral bioavailability of drug by means of D-alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS) liposomes. The nintedanib esylate-loaded TPGS liposomes were prepared by thin-film hydration method by optimizing process parameters like phospholipids:cholesterol ratio, drug loading and sonication time through the design of experiments The drug′s behavior was studied using a variety of techniques, including physicochem. characterization and in vitro and in vivo studies. TPGS liposomes had a particle size of 125 ± 6.7 nm, entrapment efficiency of 88.6 ± 4.1and zeta potential of + 46 ± 2.8 mV. X-ray diffraction anal. revealed the drug was converted to partially amorphous state, while transmission electron microscope images showed the spherical shape with TPGS on the surface of liposomes. The formulation showed Higuchi kinetics with sustained drug release of 92in 36 h. Cellular uptake of C-6-labeled liposomes was observed in A-549 cells and cytotoxicity testing revealed that liposomes were more effective than marketed formulation. The preparation was found stable in stability chamber and simulated fluids. Liposomal oral bioavailability was ∼ 6.23 times greater in Sprague-Dawley male rats compared to marketed formulation, according to in vivo pharmacokinetic data. Liposomes performed better than marketed capsules upon oral administration because of the prolonged drug release and increased oral bioavailability; as a result, the developed formulation can become a successful strategy in cancer chemotherapy.

A high-precision prediction for spatiotemporal distribution and risk assessment of antibiotics in an urban watershed using a hydrodynamic model was written by Ding, Yan;Liu, Xiaowei;Qin, Xiaodong;Chen, Yihan;Cui, Kangping. And the article was included in Chemosphere in 2022.Reference of 70458-96-7 The following contents are mentioned in the article:

A methodol. for the high-precision prediction and risk assessment of antibiotics at the watershed scale was established. Antibiotic emission inventory and attenuation processes were integrated into the MIKE 11 model to predict the spatiotemporal distribution of norfloxacin, ofloxacin, enrofloxacin, erythromycin, roxithromycin, and sulfamethoxazole in the Nanfei River watershed, China. Considering the variations in antibiotic removal in sewage treatment plants, manure composting, and lagoon systems, the high, medium, and low removal efficiencies of selected antibiotics across China were obtained and used as the best, expected, and worst scenarios, resp., to evaluate the uncertainty of antibiotic emissions. The predicted concentrations were comparable to antibiotic measurements after flow calibration. The prediction results showed that the highest concentration exposures were mainly concentrated in urban areas with a dense population. Flow variations controlled the temporal distribution characteristics of antibiotics via the dilution effect, and the concentrations of antibiotics in the dry season were 3.1 times higher than those in the wet season. The median concentrations of norfloxacin and erythromycin ranged from 111.36 ng/L to 592.33 ng/L and 106.63 ng/L to 563.01 ng/L, resp., which both posed a high risk to cyanobacteria and a medium risk to spreading antibiotic resistance. Scenario anal. further demonstrated that high removal efficiencies of these antibiotics can considerably reduce the potential ecotoxicity risks and bacterial resistance selection. The developed methodol. for predicting the distribution and risk of antibiotics was suitable for the risk assessment and control strategy of human- and livestock-sourced pollutants.

Efficient degradation of norfloxacin by carbonized polydopamine-decorated g-C₃N₄ activated peroxymonosulfate: Performance and mechanism was written by Deng, Yuqi;Liu, Shaobo;Liu, Yunguo;Tang, Yetao;Dai, Mingyang;Chen, Qiang;Wang, Huan. And the article was included in Chemosphere in 2022.Application In Synthesis of 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid The following contents are mentioned in the article:

The use of metal-free graphite carbon nitride (CN) to activate peroxymonosulfate (PMS) has attracted extensive attention for organic pollutants degradation In this work, we prepared carbonized polydopamine-decorated g-C₃N₄ (CP-700) for activation of PMS to degrade norfloxacin (NOR). The CP-700 composite was obtained by using CN as a base material on which dopamine underwent an autopolymn. reaction to form a CN-PDA complex, followed by pyrolysis. The apparent porous structure and graphitization provided a large number of active sites for catalytic degradation, enabling CP-700 to exhibit excellent catalytic performance during PMS activation. The degradation of NOR was not hindered by sulfate radical (SO·-4) and hydroxyl radical (·OH). Singlet oxygen (¹O₂) and mediated electron transfer were ultimately identified as the primary mechanisms. According to the linear pos. correlation (R2 = 0.9922) between the semi-quant. carbonyl group (C=O) and the reaction rate constant, it was determined that the carbonyl group served as the important active site. The excellent electron transfer ability of CP-700 was evidenced by electrochem. techniques and the electron transfer pathway in the system was that PMS was adsorbed on the CP-700 surface to form metastable complex, and then the electron transfer between NOR and metastable complex was achieved. Based on the non-radical pathway, CP-700/PMS system showed a high tolerance to solution pH (3.0-11.0) and inorganic anions. The cyclic degradation experiments indicated that the system maintained a high degradation capability without the addition of addnl. CP-700, elucidating its potential application in the degradation of organic pollutants in the water.
