Design, synthesis and evaluation of novel polypharmacological antichlamydial agents

Abstract Discovery of new polypharmacological antibacterial agents with multiple modes of actions can be an alternative to combination therapy and also a possibility to slow development of antibiotic resistance. In support to this hypothesis, we synthesized 16 compounds by combining the pharmacophores of Chlamydia trachomatis inhibitors and inhibitors of type III secretion (T3S) in gram-negative bacteria. In this study we have developed salicylidene acylhydrazide sulfonamides (11c & 11d) as new antichlamydial agents that also inhibit T3S in Yersinia pseudotuberculosis.

Pharmaceuticals of emerging concern in aquatic systems: Chemistry, occurrence, effects, and removal methods

In the last few decades, pharmaceuticals, credited with saving millions of lives, have emerged as a new class of environmental contaminant. These compounds can have both chronic and acute harmful effects on natural flora and fauna. The presence of pharmaceutical contaminants in ground waters, surface waters (lakes, rivers, and streams), sea water, wastewater treatment plants (influents and effluents), soils, and sludges has been well doccumented. A range of methods including oxidation, photolysis, UV-degradation, nanofiltration, reverse osmosis, and adsorption has been used for their remediation from aqueous systems. Many methods have been commercially limited by toxic sludge generation, incomplete removal, high capital and operating costs, and the need for skilled operating and maintenance personnel. Adsorption technologies are a low-cost alternative, easily used in developing countries where there is a dearth of advanced technologies, skilled personnel, and available capital, and adsorption appears to be the most broadly feasible pharmaceutical removal method. Adsorption remediation methods are easily integrated with wastewater treatment plants (WWTPs). Herein, we have reviewed the literature (1990-2018) illustrating the rising environmental pharmaceutical contamination concerns as well as remediation efforts emphasizing adsorption.

Oxidation of sulfamethoxazole by UVA radiation and modified Fenton reagent: Toxicity and biodegradability of by-products

Improvement of sulfamethoxazole (4-amino-N-(5-methylisoxazol-3-yl)- benzenesulfonamide – SMX) biodegradability using a modified Fenton’s reaction has been studied. The modification consists of replacing hydrogen peroxide with atmospheric air and adding copper sulphate as a reaction promoter. Two series of experiments were carried out. The first (Series 1) was conducted using only the catalysts with aeration. In the second series (Series 2), cycles of UVA radiation and aeration were used. During UVA radiation, the removal of sulfamethoxazole proceeds less rapidly than in only aerated solution. After 1.5 h of these two processes, the SMX degradation was 23% in Series 2 and 59% in Series 1. The opposite trend was observed for mineralization and the removal of DOC was about 5% higher in Series 2 than in Series 1. The FTIR spectra of the extracts of reaction products yielded by four organic solvents of varying polarity revealed a wide diversity of functional groups in the post-reaction mixture in comparison to the extracts from sulfamethoxazole solution. Based on FTIR analysis, several oxidation products of sulfamethoxazole are proposed. Apparently, hydroxyl radicals initially attack sulphonamide bonds, resulting in the formation of sulfanilic acid and 3-amino-5-methylisoxazole. Irrespective of the reference organism used in toxicity tests, the post-reaction mixture in the Series 2 was more toxic than the post-reaction mixture in Series 1. In contrast, the biodegradability calculated as BOD5/DOC ratio, was higher for post-reaction mixture 2 and amounted to 0.43. IWA Publishing 2009.

A novel strategy of successive non-radical and radical process for enhancing the utilization efficiency of persulfate

During the process of persulfate oxidation, side reactions such as the recombination of radicals can usually result in the low utilization efficiency of persulfate, which decreases the mineralization of target pollutants. In this study, the successive oxidation strategy was proposed based on successive non-radical and radical process (SNRP), to enhance the utilization efficiency of peroxymonosulfate (PMS), and further enhance the mineralization of sulfonamides. The results indicated that 0.04 mM of sulfonamide could be completely removed within 240 min at 1.2 mM PMS and initial pH 6.8 in the non-radical process, but the mineralization was very low (<2%). Moreover, the decomposition efficiency of PMS was less than 10% within 480 min. Fe(II) was added into the solution in which non-radicals process was performed, to initiate radical process by activating residual PMS. Compared to Fe(II)/PMS process, the SNRP process significantly increased the mineralization of sulfonamides, reaching 27.0%, 19.0%, 16.7% and 17.2%, respectively for sulfamethoxazole, sulfanilamide, sulfadiazine and sulfamerazine. The increased mineralization was due to the enhanced PMS utilization. Seven degradation products were identified in the SNRP process. Among them, hydrolyzed 3-amino-5-methyl isoxazole, (3-amino-5-methylisoxazole) sulfonic acid and 4-aminobenzenesulfinic acid produced in the non-radical oxidation process showed resistance to the subsequent radical oxidation. This study can provide a possible way to enhance the utilization efficiency of PMS as well as the mineralization of organic pollutants. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1072-67-9, help many people in the next few years.Safety of 5-Methylisoxazol-3-amine

Assessing the potential of pharmaceuticals and their transformation products to cause mutagenic effects: Implications for gene expression profiling

The selection and prioritization of pharmaceuticals and their transformation products for evaluating effects on the environment and human health is a challenging task. One common approach is based on compounds (e.g., mixture composition, concentrations), and another on biology (e.g., relevant endpoint, biological organizational level). Both of these approaches often resemble a Lernaean Hydra?they can create more questions than answers. The present study embraces this complexity, providing an integrated approach toward assessing the potential effects of transformation products of pharmaceuticals by means of mutagenicity, estrogenicity, and differences in the gene expression profiles. Mutagenicity using the tk kinase assay was applied to assess a list of 11 priority pharmaceuticals, namely, atenolol, azithromycin, carbamazepine, diclofenac, ibuprofen, erythromycin, metoprolol, ofloxacin, propranolol, sulfamethoxazole, and trimethoprim. The most mutagenic compounds were found to be beta-blockers. In parallel, the photolabile pharmaceuticals were assessed for their mixture effects on mutagenicity (tk assay), estrogenicity (T47D- KBluc assay), and gene expression (microarrays). Interestingly, the mixtures were mutagenic at the mug/L level, indicating a synergistic effect. None of the photolysed mixtures were statistically significantly estrogenic. Gene expression profiling revealed effects related mainly to certain pathways, those of the p53 gene, mitogen-activated protein kinase, alanine, aspartate, and glutamate metabolism, and translation-related (spliceosome). Fourteen phototransformation products are proposed based on the m/z values found through ultra-performance liquid chromatography?tandem mass spectrometry analysis. The transformation routes of the photolysed mixtures indicate a strong similarity with those obtained for each pharmaceutical separately. This finding reinforces the view that transformation products are to be expected in naturally occurring mixtures. Environ Toxicol Chem 2016;35:2753?2764.

Synthesis and characterization of Cu(I) and Zn(II) complexes with new sulfur-bearing isoxazole- or pyrazole-based ligands

The synthesis of the new ligands 6-(5-methyl-1,2-oxazol-3-yl)-2,3-dihydro-5H-[1,4] dithiino[2,3-c]pyrrole-5,7(6H)-dione (isox?) and 6-(3-methyl-1H-pyrazol-5-yl)-2,3-dihydro-5H-[1,4]dithiino[2,3-c]pyrrole-5,7(6H)-dione (pyraz?) and their coordination chemistry toward Cu(I) and Zn(II), was studied. The ligands and their complexes were characterized using a combination of either multinuclear NMR (1H and 13C{1H}), HRMS, FTIR or Uv-Vis spectroscopy. The solid state structures of ligand isox? and complexes [Cu(pyraz?)2]OTf and [Zn(OOCCF3)2(pyraz?)2] were determined. Interestingly, isox? presents a yellow luminescence in its free form. Additionally, the ability of isox? to coordinate as an N-O bidentate ligand or as an N-S bridge between two copper centers, forming a coordination polymer, is studied. The solid state structure of this Cu(I)-isox? 1D coordination polymer is also reported.

Sulfonamide Synthesis through Electrochemical Oxidative Coupling of Amines and Thiols

Sulfonamides are key motifs in pharmaceuticals and agrochemicals, spurring the continuous development of novel and efficient synthetic methods to access these functional groups. Herein, we report an environmentally benign electrochemical method which enables the oxidative coupling between thiols and amines, two readily available and inexpensive commodity chemicals. The transformation is completely driven by electricity, does not require any sacrificial reagent or additional catalysts and can be carried out in only 5 min. Hydrogen is formed as a benign byproduct at the counter electrode. Owing to the mild reaction conditions, the reaction displays a broad substrate scope and functional group compatibility.

Biodegradation of sulfamethoxazole and other sulfonamides by Achromobacter denitrificans PR1

This study aimed to isolate and characterize a microbial culture able to degrade sulfonamides. Sulfamethoxazole (SMX)-degrading microorganisms were enriched from activated sludge and wastewater. The resultant mixed culture was composed of four bacterial strains, out of which only Achromobacter denitrificans PR1 could degrade SMX. This sulfonamide was used as sole source of carbon, nitrogen and energy with stoichiometric accumulation of 3-amino-5-methylisoxazole. Strain PR1 was able to remove SMX at a rate of 73.6¡À9.6mumolSMX/gcell dry weighth. This rate more than doubled when a supplement of amino acids or the other members of the mixed culture were added. Besides SMX, strain PR1 was able to degrade other sulfonamides with anti-microbial activity. Other environmental Achromobacter spp. could not degrade SMX, suggesting that this property is not broadly distributed in members of this genus. Further studies are needed to shed additional light on the genetics and enzymology of this process.
