DNA damage induced with near-ultraviolet light irradiation in the presence of quinoxaline-1,4-dioxide. 1980

K Negishi, and Y Arao, and N Oka, and H Hayatsu

When Bacillus subtilis transforming DNA was irradiated with near-ultraviolet light in the presence of quinoxaline-1,4-dioxide, the activity of DNA decreased rapidly. This loss of activity was ascribed to damages on DNA that lead to chain cleavages of the molecule. A feature of this phototoxic action of the reagent is that it takes place in nitrogen atmosphere and is inhibited by oxygen.

D014466 Ultraviolet Rays That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
