DNA G-rich sequences are able to form four-stranded structures organized in stacked guanine tetrads. These structures, called G-quadruplexes, were found to have an important role in the regulation of oncogenes expression and became, for such a reason, appealing targets for anticancer drugs. Aiming at finding selective G-quadruplex binders, we have designed, synthesized and characterized a new w...

Experimental and theoretical characterization of a new Schiff-base ligand

Here, new N,N′-dipyridoxyl(4,4''-diaminodiphenylether) Schiff-base ligand has been synthesized and characterized by IR, 1H NMR and mass spectrometry. Also, geometry optimization and theoretical assignment of IR spectrum of the ligand have been computed by employing density functional theory (DFT) method. Two pyridine rings and benzene rings in the bridge region are not in the same plane. The ca...

Pyrrolobenzodiazepines (PBDs) Do Not Bind to DNA G-Quadruplexes

The pyrrolo[2,1-c][1,4] benzodiazepines (PBDs) are a family of sequence-selective, minor-groove binding DNA-interactive agents that covalently attach to guanine residues. A recent publication in this journal (Raju et al, PloS One, 2012, 7, 4, e35920) reported that two PBD molecules were observed to bind with high affinity to the telomeric quadruplex of Tetrahymena glaucoma based on Electrospray...

Synthesis and Characterization of Metal Complexes with New Unsymmetrical Schiff Base Ligand Derived from 2-Aminoethanethiol

A new unsymmetric thioether diamine N - ( 2 - ( 2 - aminophenylthio) ethyl) benzene - 1 , 2 - diamine was prepared through the nucleophilic substitution of cysteaminium chloride with 1 - chloro - 2 - nitrobenzene and then the nitro groups of prepared compuond converted to the amine by zinc powder and ammonium chloride. Then, unsymmetric Schiff bass ligand 2 - ((( 2 - (( 2 - (( 2 - (( 2 - hydrox...

Synthesis and Characterization of Novel Lead (II) Complexes with Schiff Base Iminopyridine Ligand

First, Schiff base iminopyridine ligand has been prepared by the condensation between primary amine, dimethylaniline and active carbonyl group of pyridine carboxaldehyde, then related complexes were synthesized in methanol solution. The ligand and metal complexes have been characterized by elemental analysis, UV, IR, 1 H NMR and 13CNMR spectroscopy. The spectroscopic data of metal complexes ind...
