The human selenoprotein thioredoxin reductase is involved in antioxidant defense and DNA synthesis. As increased thioredoxin reductase levels are associated with drug sensitivity to cisplatin and drug resistance in tumor cells, this enzyme represents a promising target for the development
A series of (1,4)-naphthoquinono [3,2-c]-1H-pyrazoles and their (1,4)-naphthohydroquinone derivatives 2-7 were synthesized and evaluated for antifungal, antibacterial, and anticancer activities. The structure-activity relationship of these compounds was studied and the results show that the compound 2b exhibited in vitro antifungal
The search of new anti-inflammatory drugs has been a current preoccupation, due to the need of effective drugs, with less adverse reactions than those used nowadays. Several naphthoquinones (plumbagin, naphthazarin, juglone, menadione, diosquinone and 1,4-naphthoquinone), plus p-hydroquinone and p-benzoquinone were

Naphthazarin (DHNQ, 5,8-dihydroxy-l,4-naphthoquinone) is a naturally available 1,4-naphthoquinone derivatives. In this study, we focused on elucidating the cytotoxic mechanism of naphthazarin in A549 non-small cell lung carcinoma cells. Naphthazarin reduced the A549 cell viability considerably with an IC(50) of 16.4 ± 1.6 μM.
Schistosomiasis--infection with helminth parasites in the genus Schistosoma, including S. mansoni--is a widespread, devastating tropical disease affecting more than 200 million people. No vaccine is available, and praziquantel, the only drug extensively utilized, is currently administered more than 100 million
