Interaction of DNA minor groove binder Hoechst 33258 with bovine serum albumin.
Hoechst 33258 belongs to bisbenzimidazole class of molecules having anticancer properties for their ability to inhibit topoisomerase and many other cellular processes. The aim of the present study is to understand the nature of Hoechst 33258-bovine serum albumin (BSA) binding interactions by using absorption, fluorescence and circular dichrorism (CD) measurements under simulative physiological ...
متن کاملBuoyant density of DNA-Hoechst 33258 (bisbenzimide) complexes in CsCl gradients: Hoechst 33258 binds to single AT base pairs.
Buoyant density of DNA in CsCl gradients with Hoechst 33258 (bisbenzimide) was investigated as a function of guanine plus cytosine content of the DNA (%GC; in mole percent). A formula for calculating %GC from the refractive index (nD) of the isopycnic CsCl/Hoechst 33258 solution over the range of 0-75 %GC was established: %GC = 351762.28 X nD - 123778.66 X nD2 - 249789.47 (the coefficients must...
متن کاملDifferent Modes of Binding of Hoechst 33258 with Dna
Spectrophotometric study of Hoechst 33258 binding to DNA has been investigated. It was shown that this ligand forms at least two types of complexes at 0.002 M and 0.02M ionic strengths of solution. One of them is strong, the other is weak. It was revealed that at 0.02M ionic strength of solution, the binding constant value by strong mode is one order higher than at 0.002M. It was obtained that ...
متن کاملBinding Mechanisms of Methylene Blue and Hoechst 33258 with Dna
In this work the data of methylene blue (MB) and Hoechst 33258 interaction with DNA are presented. It has been shown that at 0.002 M ionic strength of solution MB is bound to double-stranded DNA by three modes: intercalation, semi-intercalation and electrostatic. It was revealed that at higher ionic strengths of solution complete intercalation of MB becomes thermodynamically unacceptable. It wa...
متن کاملHoechst 33258, distamycin, and netropsin are among a number of compounds that bind in the minor groove of DNA
number of compounds that bind in the minor groove of DNA and exhibit various degree of antitumour activity. Several high resolution crystal and NMR structures have been determined for these ligands bound to short oligonucleotides and provide valuable insights into the details of their interaction. The Hoechst 33258 is bound in the minor groove, with the planar benzimidazole groups oriented para...
