Structural studies of pterin-based inhibitors of dihydropteroate synthase.

Kirk E Hevener et al.

Journal of medicinal chemistry, 53(1), 166-177 (2009-11-11)

Dihydropteroate synthase (DHPS) is a key enzyme in bacterial folate synthesis and the target of the sulfonamide class of antibacterials. Resistance and toxicities associated with sulfonamides have led to a decrease in their clinical use. Compounds that bind to the

Arylamine N-acetyltransferase activity of the human placenta.

L O Derewlany et al.

The Journal of pharmacology and experimental therapeutics, 269(2), 756-760 (1994-05-01)

The fetus is exposed to almost all of the substances found in the maternal circulation whether nutrients or foreign chemicals ("xenobiotics"). The main route of exposure is the placenta. The placenta is metabolically active toward xenobiotics and the nature of

Linkage and branch analysis of high-mannose oligosaccharides using closed-ring labeling of 8-aminopyrene-1,3,6-trisulfonate and p-aminobenzoic ethyl ester and negative ion trap mass spectrometry.

Shu-Ting Chen et al.

Journal of the American Society for Mass Spectrometry, 23(8), 1408-1418 (2012-06-08)

A strategy based on negative ion electrospray ionization tandem mass spectrometry and closed-ring labeling with both 8-aminopyrene-1,3,6-trisulfonate (APTS) and p-aminobenzoic acid ethyl ester (ABEE) was developed for linkage and branch determination of high-mannose oligosaccharides. X-type cross-ring fragment ions obtained from
