Abstract:

The low-temperature fluorescence spectroscopy(LTFS) and fluorescence line-narrowing spectroscopy(FLNS) are useful tool to study the DNA adducts from various PAHs. The results of analysis on DNA adducts of metabolites of carcinogenic agents suggested that the existence of multiple conformations. It is believed that the conformation of DNA adducts is important to its carcinogenesis. So we theoretically computed the wavelength of the DNA adducts and study the conformations of the adducts together with experimental results try to know the relationship of conformations of adducts and its genotoxity.
