In many diseases such as cancer, simultaneous use of two or more pharmacologically active agents will be more effective and have fewer side effects. In this study a new palladium(II) complex with formula of [Pd(phen)(py-dtc)]NO3 (where is phen 1,10-phenanthroline and py-dtc is n-propyldithiocarbamate), was synthesized. The cytotoxic activity of this complex was tested against leukemia K562 cell...

DNA is not only an essential research subject for biologists, but also it raises very interesting questions for physicists.The open states in DNA double helix can lead to topological solitons. Since DNA is a very long molecule )of order a meter or so long) and nano-scale width, solitons can propagate along the molecule. In this paper, considering a correction term in the interaction potential b...

FT-SERS (Fourier Transform Surface Enhanced Raman Scattering) of adriamycin and its complex with DNA is reported. It is shown that in agreement with previous Raman studies the interaction of adriamycin  with DNA takes place through an intercalation mechanism. The presence of a new band at 731 cm-1 suggests that ring D of adriamycin is not involved in the intercalation process.

this study aims to design some dual-target anticancer candidates, capable to act as an alkylating agent as well as a thymidylate synthase (ts) inhibitor. the designed scaffold is a combination of nucleobase, amino acid and aziridine structures. the candidates are docked into ts and three dna double strand structures and evaluated based on their binding interaction energies and ligand efficienci...

ft-sers (fourier transform surface enhanced raman scattering) of adriamycin and its complex with dna is reported. it is shown that in agreement with previous raman studies the interaction of adriamycin  with dna takes place through an intercalation mechanism. the presence of a new band at 731 cm-1 suggests that ring d of adriamycin is not involved in the intercalation process.

Maryam Dookheh Nasrin Sohrabi,

In this study at first , an azo dye, 2,7- naphthalenediol, 2-[(4-Bromophenyl)azo (BPAND) as a ligand has been synthesized by addition of p-Bromoaniline to the modified montomorillonite K10 clay. This ligand was characterized using 1H-NMR, UV-Vis and IR spectroscopies. Subsequently, its interaction with calf thymus deoxyribonucleicacid ,ct-DNA was investigated in 5 mM phosphate buffer solution, ...
