Decomposition of sulfamethoxazole and trimethoprim by continuous UVA/LED/TiO2 photocatalysis: Decomposition pathways, residual antibacterial activity and toxicity

In this study, continuous LED/UVA/TiO2 photocatalytic decomposition of sulfamethoxazole (SMX) and trimethoprim (TMP) was investigated. More than 90% of SMX and TMP were removed within 20 min by the continuous photoreactor (with the initial concentration of 400 ppb for each). The removal rates of SMX and TMP decreased with higher initial antibiotics loadings. SMX was much easier decomposed in acidic condition, while pH affected little on TMP’s decomposition. 0.003% was found to be the optimum H2O2 dosage to enhance SMX photocatalytic decomposition. Decomposition pathways of SMX and TMP were proposed based on the intermediates identified by using LC?MS?MS and GC?MS. Aniline was identified as a new intermediate generated during SMX photocatalytic decomposition. Antibacterial activity study with a reference Escherichia coli strain was also conducted during the photocatalytic process. Results indicated that with every portion of TMP removed, the residual antibacterial activity decreased by one portion. However, the synergistic effect between SMX and TMP tended to slow down the antibacterial activity removal of SMX and TMP mixture. Chronic toxicity studies conducted with Vibrio fischeri exhibited 13?20% bioluminescence inhibition during the decomposition of 1 ppm SMX and 1 ppm TMP, no acute toxicity to V. fischeri was observed during the photocatalytic process.

Proposal for crystallization of 3-amino-4-halo-5-methylisoxazoles: An energetic and topological approach

The supramolecular structure of 3-amino-4-halo-5-methylisoxazoles (halo = Cl, Br, and I) was investigated in order to suggest a route for crystallization of small molecules. The hierarchy of intermolecular interactions during the growth of the crystal was established by X-ray diffraction, 1H NMR titration, QTAIM analysis and quantum mechanical calculations. The relationship between QTAIM and energetic data was the fundamental innovation in this work. It allowed partitioning of the dimer interaction energy between interacting atoms. The partitioning shows the cooperation of the intermolecular interactions in the stabilization of the dimers and led to observation of the energetic consequences that small changes in the molecular structure of each compound may have on the crystal packing. The proposed route for the crystallization of the supramolecular cluster was based on the energetic hierarchy, in which the hydrogen bond is the strongest interaction and the first to form, and the pi-interactions are weaker than the hydrogen bond and cannot compete with it. However, the pi-interactions are responsible for the growth of the crystal, connecting the rising layers of the hydrogen bond dimers. The other interaction formed, the halogen bond, is too weak to compete with the other two interactions, but it is fundamental for linking the layer that leads to the final three-dimensional arrangement. Finally, a new way of understanding the crystallization process and the design of new materials is presented.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 1072-67-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1072-67-9, in my other articles.

Insights on sulfamethoxazole bio-transformation by environmental Proteobacteria isolates

Although sulfonamide residues are frequently reported as freshwaters contaminants, information on the ability of native bacteria to modify these synthetic antibiotics is scarce. Our purpose was to investigate the potential of bacteria from different aquatic environments to cleave or transform sulfamethoxazole (SMX) and infer on their ability to reduce the toxicity of this antibiotic. From a collection of about 100 Proteobacteria, 47 strains previously isolated from drinking water, surface water, and wastewater grew in the presence of 200 muMSMX, and were further studied. Out of these, 14 strains, mostly from mineral drinking water, transformed SMX into equimolar amounts of the lesser toxic derivative N4-acetyl-sulfamethoxazole. The highest percentage of SMX transformation was recorded for two strains affiliated to Pseudomonas mandelii. For P. mandelii McBPA4 higher SMX transformation rate and extent were observed in fed-batch (?8 muMSMX/h, 81%) than in batch conditions (?5 muMSMX/h, 25%), but similar specific transformation rates were found in both cultivation modes (?20 mumolSMX/gcell dry weight/h), indicating the dependence of the process on the microbial load. These results evidence that the capacity to transform synthetic antibiotics may be common among bacteria and highlight the potential of environmental bacteria in attenuating the potential adverse effects of pollution with sulfonamides.

Identification and determination of metabolites and degradation products of sulfonamide antibiotics

Sulfonamide residues have been detected in all kinds of environmental water matrix. However, little attention has been so far paid to their metabolites and degradation products, and very few articles have included them in their analytical scope. The main goal of this article is to review those research studies in which both parent drugs and their respective metabolites have been considered together. We review the analytical methodologies used and assess biotic and abiotic degradation mechanisms of these antibiotics, and briefly evaluate their potential toxicity in the environment.

4-Chlorocolchicine derivatives bearing a thiourea side chain at the C-7 position as potent anticancer agents

A series of 4-substituted colchicine derivatives were synthesized and evaluated with an eye toward developing new anticancer agents. As a result, 4-chlorocolchicine derivatives bearing a thioureide side chain at the C-7 position were found to exhibit significant cytotoxicities to three human cancer cell lines (A549, HT-29, and HCT116). In particular, compound 26 having an ethylthioureide group at the C-7 had high antitumor activity in vivo and a broad effective dosage range. Furthermore, compound 58, which has a (5-methylpyrazol-3-yl)thioureide group at the C-7 side chain, exhibited strong cytotoxicity and desirable metabolic stability in vitro.
