Covalent Binding of Elliptinium Acetate (NSC 264137) to Nucleic Acids of L1210 Cells in Culture1
I Ilipiiiiiiiin acétate(9-OH-NME; Celiptium) is an antineoplastic agent currently used in the treatment of metastatic breast cancer and is known to intercalate into DNA. Previous studies have demonstrated that this molecule can be oxidized, yielding a reactive electrophilic form, which is able to bind covalently to a nucleophilic biological molecule. In this work, we evidenced a covalent bindi...

متن کاملAnion binding to nucleic acids.
Nucleic acids are generally considered as efficient cation binders. Therefore, the likelihood that negatively charged ions might intrude their first hydration shell is rarely considered. Here, we show on the basis of (i) a survey of the Nucleic Acid Database, (ii) several structures extracted from the Cambridge Structural Database, and (iii) molecular dynamics simulations, that the nucleotide e...
متن کاملBinding of Hoechst with nucleic acids using fluorescence spectroscopy
It has been shown that polarity of environment around Hoechst 33342 is almost unchanged while sorption of this fluorescent dye on a surface of the hairpin oligonucleotide HP1, t-RNA and DNA. At small concentrations, this dye, adsorbed on the surface of DNA, RNA or HP1, does not show any specificity to certain nucleotides. In the case of unwound sites of DNA or HP1, it can bind inside, but witho...
متن کاملLeukocyte protease binding to nucleic acids promotes nuclear localization and cleavage of nucleic acid binding proteins.
Killer lymphocyte granzyme (Gzm) serine proteases induce apoptosis of pathogen-infected cells and tumor cells. Many known Gzm substrates are nucleic acid binding proteins, and the Gzms accumulate in the target cell nucleus by an unknown mechanism. In this study, we show that human Gzms bind to DNA and RNA with nanomolar affinity. Gzms cleave their substrates most efficiently when both are bound...
