Bifunctional photobinding of psoralen to single stranded nucleic acids.
As psoralen and other furocoumarin derivatives, intercalated between two base pairs of native DNA, under irradiation at 365 nm form inter-strand cross-linkings as a consequence of bifunctional addition, the writers have investigated the ability of psoralen to give such bifunctional photo additions, too, with nucleic acids with disordered or partilly disordered structure (denatured DNA and r-R ...
متن کاملPsoralen photosensitization of L 1210 leukaemia cells: an approach to a new combined therapy.
Psoralen photosensitization of L 1210 cells has a strong effect on DNA and RNA syntheses and this result appears connected with the psoralen photobinding to DNA. Protein synthesis is less sensitive and its inhibition seems due to a different photochemical interaction, very likely to the psoralen photobinding to RNA. A combined therapy using cyclophosphamide and L 1210 cells psoralen-photoinacti...
متن کاملPsoralen Inactivation of Viruses: A Process for the Safe Manipulation of Viral Antigen and Nucleic Acid
High consequence human pathogenic viruses must be handled at biosafety level 2, 3 or 4 and must be rendered non-infectious before they can be utilized for molecular or immunological applications at lower biosafety levels. Here we evaluate psoralen-inactivated Arena-, Bunya-, Corona-, Filo-, Flavi- and Orthomyxoviruses for their suitability as antigen in immunological processes and as template f...
متن کاملDefinitions and nomenclature of nucleic acid structure components.
We report here recommendations for the definitions and nomenclature of nucleic acid structure parameters. These recommendations result from discussions at an EMBO Workshop on DNA Curvature and Bending held at Churchill College, Cambridge, in September 1988.
متن کاملSubtle interactions of cupric ion with nucleic acid and components.
In a study of the mechanism of activation of the copper enzyme, ascorbic acid oxidase, it was observed that most compounds which activate this enzyme have the common property of forming complex compounds with cupric ion (l-3). Among these activating substances were ribonucleic acid,’ deoxyribonucleic acid, and certain of their constituents. These substances showed a surprisingly strong affinity...
