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

Demyelinating diseases: myeloperoxidase as an imaging biomarker and therapeutic target.

Reza Forghani et al.

Radiology, 263(2), 451-460 (2012-03-23)

To evaluate myeloperoxidase (MPO) as a newer therapeutic target and bis-5-hydroxytryptamide-diethylenetriaminepentaacetate-gadolinium (Gd) (MPO-Gd) as an imaging biomarker for demyelinating diseases such as multiple sclerosis (MS) by using experimental autoimmune encephalomyelitis (EAE), a murine model of MS.

Aquatic photodegradation of sunscreen agent p-aminobenzoic acid in the presence of dissolved organic matter.

Lei Zhou et al.

Water research, 47(1), 153-162 (2012-10-23)

Dissolved organic matter (DOM) is an important photosensitizer for the phototransformation of organic contaminants in sunlit natural waters. This article focuses on the photolysis kinetics and mechanism of sunscreen agent p-aminobenzoic acid (PABA) in the presence of four kinds of
