Biological evaluation of 2,3-dichloro-5,8-dimethoxy-1,4-naphthoquinone as an anti-breast cancer agent.
BACKGROUND Breast cancer is the most frequent cancer and the second leading cause of cancer deaths in women today. A number of 1,4-naphthoquinone derivatives have been found to possess significant pharmacological effects associated with marked antimicrobial and antitumor activities. In the present study, the in vitro effect of 2,3-dichloro-5,8-dimethoxy-1,4-naphthoquinone (DCDMNQ) was evaluated...
متن کاملProbing the adsorption and orientation of 2,3-dichloro-5,8-dimethoxy-1,4-naphthoquinone on gold nano-rods: A SERS and XPS study
2, 3-Dichloro-5,8-dimethoxy-1,4-naphthoquinone (DDNQ) is a synthetic naphthaquinone which has shown reduced chemotoxicity and enhanced chemotherapeutic activity in in vitro studies. The ability of DDNQ to serve as a chemical dopant of graphene resulting improved performance of graphene by tuning its band gap is also being explored. In this report surface enhanced Raman scattering (SERS) spectro...

About 20 years have elapsed since those studies were done. During this period, many changes that might influence teenage reproductive behavior and how it is viewed have taken place within the industrialized world. The proportion of births to unmarried women has risen,2 and nonmarital childbearing is more acceptable, both among adolescents and among women older than 20. Access to contraception a...
متن کاملSite of Action of 2,5-Dimethoxy-3,6-Dichloro-/?-Benzoquinone in the Photosynthetic Electron Transport Chain
Dichlorodimethoxy-/?-benzoquinone (DCDMQ) was tested for its site of action in the photo synthetic electron transport chain. Hill reaction mediated by DCDMQ was insensitive to DBMIB (1 nm) but sensitive to DCMU, suggesting its site of action before plastoquinone but after Q the primary electron acceptor of photosystem II. Extraction of freeze-dried chloroplasts with heptane and analyzing their...
متن کاملC 1 NQR , Crystal Structure , and Pyroelectricity of 2 , 3 - Dichloro - l , 4 - naphthoquinone *
The C1 NQR spectra of the two phases (phases I and II) of 2,3-dichloro-l,4-naphthoquinone were studied from 77 to 394 K. The crystal structure determination of the triclinic phase (phase I) was refined by single crystal X-ray diffraction. Phase I crystallizes in the space group C/-P1. The unit cell (Z = 4) has the dimensions a = 1614.3(4) pm, 6 = 828.1 (3) pm, c = 733.2(3) pm, a = 67.02(l)°, /?...
