Sulfonamide-based antibiotics are often detected in surface water and secondary wastewater effluent and pose an eminent threat for the development of antibiotic resistance bacteria and genes in aquatic environment. This paper presents the kinetics and stoichiometry of the oxidation of sulfonamides (sulfaguanidine, sulfisoxazole, sulfamethizole, sulfamethoxazole (SMX), sulfamethazine, and sulfadimethoxine) by ferrate(VI) (FeO42-, Fe(VI)) in the acidic to basic pH range (2.0-9.6); apparent second-order rate constants (kapp, M-1s-1) decreased non-linearly with increase in pH. The specific rate constants for the individual Fe(VI) species (H3FeO4+, H2FeO4, HFeO4-, and FeO4-) were determined using acid-base equilibria of Fe(VI) and sulfonamides. The reactivity order of Fe(VI) species with the neutral sulfonamide was H3FeO4+>H2FeO4>HFeO4-, which generally explained the pH dependence behavior of rate constants. Detailed studies regarding the resultant oxidized products (OPs) using liquid chromatography-mass spectrometry/mass spectrometry were performed for oxidation of SMX at different molar ratios of Fe(VI) to SMX (i.e., 1.0-15) and at different pH’s (i.e., 4.0, 7.0, and 9.0); oxidative degradative products include 3-amino-5-methylisoxazole, and hydroxyl-, hydroxylamine-, nitroso-, and nitro-derivatives of SMX. The possible reaction pathways comprise the SN bond cleavage, ring-opening of isoxazole moiety, oxidation of aromatic amine, and the hydroxylation of the benzene ring; different OPs formed under acidic, neutral, and basic pH conditions are described. The value of kapp, 8.9×102M-1s-1 at pH 7.0 suggests the oxidative transformation of SMX in seconds by 1mgL-1 K2FeO4 and interestingly, the removal of SMX could be achieved at neutral pH by Fe(VI) in the presence of humic acid.

Heterocyclic 5-amino uracil derivatives were prepared by catalytic amination of 1,3-dibenzyl-5-iodouracil using (CuOTf)2·PhH, 1,10-phenanthroline, dibenzylidene acetone, and Cs2CO3 as base in xylenes at 95C. Imidazole and 2-amino thiazoline were problematic using the Cu catalyst, but were effectively coupled using Ni(COD)2, dppf, and NatOBu in toluene at 100C. These are the first examples of catalytic amination with a uracil substrate.

Electrochemical technology has attracted increasing interest in recent years as an environment-friendly solution to many industrial problems and challenges. First, we give an overview on the fundamentals of electrochemical processes for the removal of pharmaceuticals from water, particularly electrochemical oxidation and Fenton-based processes, such as electro-Fenton and ultraviolet (UV) and solar photoelectro-Fenton, that have improved performance. We also mention other less studied methods, although the main focus is on reactivity elucidation by chromatography with UV or conductivity detection, especially by mass spectrometry techniques (e.g. coupled to gas chromatography or liquid chromatography), in order to discuss the degradation pathways of pharmaceuticals on the basis of the reactive species electrogenerated in each technology. In some cases, simultaneous assessment of toxicity adds crucial information for the future integration of these technologies in water-treatment facilities where pharmaceuticals and their byproducts can occur.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1072-67-9 is helpful to your research. Electric Literature of 1072-67-9

The degradation of sulfamethoxazole (SMX) by several advanced oxidation processes (AOPs) is carried out in the presence of different catalysts. The catalysts used consisted of carbon nanotubes (CNT), titanium dioxide (TiO2), a composite of carbon nanotubes and titanium dioxide (TiO2/CNT), and iron supported on carbon nanotubes (Fe/CNT). SMX removal was evaluated by catalytic ozonation, photocatalysis, catalytic oxidation with hydrogen peroxide, and combinations of these processes. The evolution of the SMX concentration during reaction time, the mineralization degree, the toxicity of the treated solution, and the formation of organic intermediates and ions were monitored. Ozonation catalyzed by Fe/CNT and CNT and photocatalytic ozonation in the presence of CNT presented the fastest degradation of SMX, whereas photocatalytic ozonation with CNT showed the best results in terms of organic matter removal (92% of total organic carbon (TOC) depletion). Total mineralization of the solution and almost complete reduction of toxicity was only achieved in the photocatalytic ozonation with H2O2 and Fe/CNT catalysts. The compound 3-amino-5-methylisoxazole was one of the first intermediates formed during SMX degradation. p-Benzoquinone was only formed in photocatalysis. Oxalic and oxamic acids were also detected and in most of the catalytic processes they appeared in small amounts. Ion concentrations increased with the reaction time.

This contribution describes the initial preparation of two potent beta-3 receptor agonists 1 and 2. Subsequent scale up of these two compounds was required for further evaluation and proceeded via a common key amine intermediate 24. Synthesis of this key intermediate by way of a Ritter reaction was a vital step in the sequence. Enantioselective Noyori hydrogenation reactions gave access to the chiral epoxides necessary to make the target compounds. Chemistry was developed for the selective dehalogenation of the 2-chloropyridyl group in the presence of a sensitive isoxazole unit to provide access to 1.

Mechanisms of magnesium homeostasis in Mycobacterium tuberculosis are poorly understood. Here, we describe the characterization of a pyrimidinetrione amide scaffold that disrupts magnesium homeostasis in the pathogen by direct binding to the CorA Mg2+/Co2+ transporter. Mutations in domains of CorA that are predicted to regulate the pore opening in response to Mg2+ ions conferred resistance to this scaffold. The pyrimidinetrione amides were cidal against the pathogen under both actively replicating and nonreplicating conditions in vitro and were efficacious against the organism during macrophage infection. However, the compound lacked efficacy in infected mice, possibly due to limited exposure. Our results indicate that inhibition of Mg2+ homeostasis by CorA is an attractive target for tuberculosis drug discovery and encourage identification of improved CorA inhibitors.
