Henderson, J. Frank published the artcileInhibition of purine metabolism in Ehrlich ascites carcinoma cells by phenanthridinium compounds related to ethidium bromide, Name: Dimidium bromide, the publication is Cancer Research (1963), 491-5, database is CAplus and MEDLINE.
The effect of 10 phenanthridinium derivatives on the incorporation of adenine and glycine into the nucleic acids and proteins of Ehrlich ascites carcinoma cells in vitro, has been studied. Only 1 compound markedly inhibited incorporation of glycine into nucleic acids and proteins, whereas all the drugs inhibited incorporation of adenine into nucleic acids.
Cancer Research published new progress about 518-67-2. 518-67-2 belongs to bromides-buliding-blocks, auxiliary class Other Aromatic Heterocyclic,Salt,Amine,Benzene, name is Dimidium bromide, and the molecular formula is C20H18BrN3, Name: Dimidium bromide.
