Dihydropteroate synthase gene mutations in Pneumocystis and sulfa resistance [PDF]

open access: yes, 2004
Pneumocystis pneumonia (PCP) remains a major cause of illness and death in HIV-infected persons. Sulfa drugs, trimethoprim-sulfamethoxazole (TMP-SMX) and dapsone are mainstays of PCP treatment and prophylaxis.

Transfer of Sulfamethazine from Contaminated Beeswax to Honey [PDF]

open access: yes, 2010
A liquid chromatographic tandem mass spectrometric method for the determination of sulfa drugs in beeswax was developed. When performing residue control on beeswax intended for the fabrication of wax foundations, residues of sulfonamides were found.

Síntese de amidas e sulfonamidas de beta-D-galactopiranosilamina e beta-lactosilamina e avaliação de suas interações com lectinas de Erythrina cristagalli e de Ricinus communis Synthesis of amides and sulfonamides of beta-D- galactopyranosylamine and beta-lactosylamine and evaluation of their interactions with the lectins from Erythrina cristagalli and Ricinus communis

open access: yesQuímica Nova, 2007
We report herein the synthesis of some beta-D-galactopyranosylamine and beta-lactosylamine amides and sulfonamides. The interactions of these compounds with lectins from the seeds of Erythrina cristagalli (LEC) and Ricinus communis (RCA120) were ...

Metal‐Free Electrochemical Synthesis of Sulfonamides Directly from (Hetero)arenes, SO2, and Amines

open access: yesAngewandte Chemie, 2020
Sulfonamides are among the most important chemical motifs in pharmaceuticals and agrochemicals. However, there is no methodology to directly introduce the sulfonamide group to a non‐prefunctionalized aromatic compound.

Synthesis of Novel Aryl(heteroaryl)sulfonyl Ureas of Possible Biological Interest

open access: yesMolecules, 2010
The course of reaction of aryl and heteroaryl sulfonamides with diphenylcarbonate (DPC) and 4-dimethylaminopyridine (DMAP) was found to depend on the pKa of the sulfonamide used.

Synthesis of Sulfonyl Fluorides from Sulfonamides

open access: yesAnnalen der Pharmacie, 2020
A simple and practical synthesis of sulfonyl fluorides from sulfonamides is reported. The method capitalizes on the formation of the sulfonyl chloride by virtue of the reaction of Pyry-BF4 and MgCl2, and subsequent in situ conversion to the more robust ...

Gold-catalyzed intermolecular hydroamination of allenes with sulfonamides

open access: yesBeilstein Journal of Organic Chemistry, 2013
A co-catalyst of (PPh3)AuCl/AgOTf for the intermolecular hydroamination of allenes with sulfonamides is shown. The reaction proceeded smoothly under mild conditions for differently substituted allenes giving N-allylic sulfonamides in good yields with ...
