Removal of sulfamethoxazole and sulfapyridine by carbon nanotubes in fixed-bed columns [PDF]

open access: yes, 2013
Sulfamethoxazole (SMX) and sulfapyridine (SPY), two representative sulfonamide antibiotics, have gained increasing attention because of the ecological risks these substances pose to plants, animals, and humans.

Preassembly‐Controlled Radical Recombination at Bismuth: Decarboxylative C─N Coupling with Sulfonamides

open access: yesChemistry – A European Journal, EarlyView.
Radical processes involving bismuth hold great potential, but innovative strategies are required to control the reactivity of bismuth intermediates. Herein, we report a direct photochemical decarboxylation with molecular bismuth for C─N coupling of benzylic carboxylic acids and sulfonamides.

The effects of endocrine‐disrupting chemicals on ovarian‐ and ovulation‐related fertility outcomes

open access: yesMolecular Reproduction and Development, Volume 89, Issue 12, Page 608-631, December 2022., 2022
Abstract Exposure to endocrine‐disrupting chemicals (EDCs) is unavoidable, which represents a public health concern given the ability of EDCs to target the ovary. However, there is a large gap in the knowledge about the impact of EDCs on ovarian function, including the process of ovulation.

A Scaffold‐Diversity Synthesis of Biologically Intriguing Cyclic Sulfonamides

open access: yesChemistry, 2019
A “branching–folding” synthetic strategy that affords a range of diverse cyclic benzo‐sulfonamide scaffolds is presented. Whereas different annulation reactions on common ketimine substrates build the branching phase of the scaffold synthesis, a common ...

Synthesis of 2‐(Trifluoromethyl)Azetidines by Strain‐Release Reactions of 2‐(Trifluoromethyl)‐1‐Azabicyclo[1.1.0]Butanes

open access: yesChemistry – A European Journal, EarlyView.
2‐(Trifluoromethyl)‐1‐azabicyclo[1.1.0]butanes, available by diastereoselective cyclopropanation of 2‐(trifluoromethyl)‐2H‐azirines, can be successfully involved in strain‐release ring‐opening processes, as illustrated by their reaction with benzyl chloroformate, trifluoroacetic anhydride or palladium‐catalyzed hydrogenolysis.

A randomized, pilot trial comparing full versus escalating dose regimens for the desensitization of AIDS patients allergic to sulfonamides

open access: yesBrazilian Journal of Infectious Diseases
Sulfonamides are drugs extensively used in the management of AIDS patients. However, the use of sulfonamides is often associated with the development of allergic reactions, provoking the substitution of the drug (by another that may be less effective ...
