Sulfonamide antibiotics are a commonly used group of compounds in animal husbandry. They are excreted with manure, which is collected in a storage lagoon in certain types of confined animal feeding operations. Flood irrigation of forage fields with this liquid manure creates the potential risk of groundwater contamination in areas with shallow groundwater levels. We tested the hypothesis that-i...
This paper proposes a method for sensing affinity interactions by triggering disruption of self-assembly of ion channel-forming peptides in planar lipid bilayers. It shows that the binding of a derivative of alamethicin carrying a covalently attached sulfonamide ligand to carbonic anhydrase II (CA II) resulted in the inhibition of ion channel conductance through the bilayer. We propose that the...
Essential oils (EOs), as unique natural products, are promising resources for the discovery of green agrochemicals. The main ingredient geraniol citronella oil was found to exhibit substantial antifungal activities in this study. Therefore, a series novel geranyl aromatic sulfonamide compounds were synthesized and display considerable activities. Two thiofuran-sulfonamide 4c-1 (median effective...
BACKGROUND The red fluorescent dye Sulforhodamine 101 (SR101) has been used in neuroscience research as a useful tool for staining of astrocytes, since it has been reported as a marker of astroglia in the neocortex of rodents in vivo. The aim of this work is to label SR101 with positron emission radionuclides, in order to provide a radiotracer to study its biological behavior. This is the first...
Lack of correlation between quantitative minimal inhibitory concentration (MIC) determinations and disk diffusion susceptibility tests in our laboratory prompted a study to reevaluate the use of the disk diffusion test for sulfonamide susceptibility testing of Neisseria meningitidis. One hundred and sixty-three recent clinical isolates of N. meningitidis were examined for sulfonamide susceptibi...
روشهای نمونهبرداری بدون قطعه نمونه (خطی یا فاصلهای) از شیوههای مهم آماربرداری در جنگلاند. در این تحقیق بهمنظور بررسی کارایی روش نمونهبرداری فاصلهای نزدیکترین همسایۀ پیوسته (C-nn)، محدودهای به مساحت 220 هکتار در بخش چلیر جنگل خیرود نوشهر انتخاب شد. سپس نمونهبرداری به دو روش، یکی با قطعات نمونه دایرهای 10 آری (مرسوم در جنگلهای شمال کشور) و دیگری بهروش فاصلهای C-nn...
Background and purpose: Emerging pollutants such as antibiotics are resistant to biodegradation. The aim of this study was to compare the effect of photocatalytic and Ozonation photolysis on decomposition of Sulfonamide antibiotics (Sulfacetamide, Sulfathiazole, Sulfamethoxazole, and Sulfadiazine) in aquatic environments. Materials and methods: In this study, experiments were conducted discont...
Sulfonamide gehören zu den wichtigsten funktionellen Gruppen in Pharmazeutika und Agrochemikalien. Es gibt jedoch keine Methode, um die Sulfonamidgruppe direkt eine nicht vorfunktionalisierte aromatische Verbindung einzuführen. Wir stellen hier das erste dehydrierende elektrochemische Verfahren zur Synthese von Sulfonamiden vor, indem inhärente Reaktivität (Hetero)arenen einer hochkonvergenten ...
