Antibiotics have been an emerging concern due to the potential adverse threat on environment and human health. Studies presence fate of antibiotics in Chinese aqueous environments increased past few years. Nevertheless, distribution contributing development dissemination antibiotic resistance China nationwide remains unclear. This review summarizes temporal spatial different environmental syste...

The presence of antibiotics in crops is mainly caused by their irrigation with reclaimed wastewater and the use organic amendments animal origin. During this work, fate sulfonamide tomato crop has been assessed two commercial greenhouses located Almería (Spain) irrigated wastewater. Samplings were made annually for years. Sulfonamides several parts plant (roots, leaves fruits) as well wastewate...

New novel derivatives of N-((5-((6-oxido-6-(4 substituted phenoxy)-4,8-dihydro-1H-[1,3,2] dioxaphosphepino [5,6-c]pyrazol-1-yl) methyl)-1,3,4-thiadiazol-2-yl)carbamoyl) substituted benzene sulfo namides (7a-o as depicted in scheme) were Synthesized by condensation reaction of 4substituted Phenyl phosphorodichloridates (6a-c) and N-((5-((4,5-bis(hydroxymethyl)-1H-pyrazol-1-yi)methyl)1,3,4-thiadi...

The photosulfochlorination of n-tetradecane by sulfuryl chloride leads to a reaction mixture containing unreacted n-tetradecane, chloro n-tetradecanes and n-tetradecanesulfonyl chlorides. Direct and simultaneous GC analysis of the mixture of the sulfochlorinated and chlorinated isomers is followed by mass spectrometry identification of all the components either by electron impact (EI-MS) and by...

The selective inhibition of cancer-associated human carbonic anhydrase (CA) enzymes, specifically CA IX and XII, has been validated as a mechanistically novel approach toward personalized cancer management. Herein we report the design and synthesis of a panel of 24 novel glycoconjugate primary sulfonamides that bind to the extracellular catalytic domain of CA IX and XII. These compounds were sy...

Between 1935 and 1937, Leonard Colebrook showed that sulfonamides, a class of antibacterial drugs, worked as an effective treatment for puerperal fever. Puerperal fever is a bacterial infection that can occur in the uterus [2] of women after giving birth. At the time of Colebrook?s study, puerperal fever remained a common disease due to both the lack of hygienic practices in hospitals and a tre...

Metal complexes of heterocyclic sulfonamides possessing carbonic anhydrase (CA) inhibitory properties were recently shown to be useful as intraocular pressure (IOP) lowering agents in experimental animals, and might be developed as a novel class of antiglaucoma drugs. Here we report the synthesis of a heterocyclic sulfonamide CA inhibitor and of the metal complexes containing main group metal i...

Metal complexes of a heterocyclic sulfonamides possessing very strong carbonic anhydrase (CA) inhibitory properties, i.e., 5-(p-fluorobenzenesulfonylamido)-1,3,4-thiadiazole-2-sulfonamide (p-fluorobenzolamide) were prepared. The new complexes contained metal ions such as Zn(II), Cu(II), Co(II), Ni(II), Cd(II) and Mn(II). The new compounds were characterized by standard physico-chemical procedur...

Target-protein degradation is an emerging field in drug discovery and development. In particular, the substrate-receptor proteins of the cullin-ubiquitin ligase system play a key role in selective protein degradation, which is an essential component of the anti-myeloma activity of immunomodulatory drugs (IMiDs), such as lenalidomide. Here, we demonstrate that a series of anticancer sulfonamides...
