It is generally considered as a cytotoxic drug which kills cancer cells by damaging DNA and inhibiting DNA synthesis. How cells respond to cisplatin-induced DNA damage plays a critical role in deciding cisplatin sensitivity.

2005-01-01 · Cisplatin and oxaliplatin DNA adducts cis -Diamminedichloroplatinum (II) (cisplatin) and cis -diammine-1,1-cyclobutane dicarboxylate (carboplatin) are widely used in chemotherapy, and are particularly effective in the treatment of testicular, ovarian, head, neck and non-small cell lung cancer.

We present here data on DNA-adduct formation by cisplatin, lobaplatin and oxaliplatin in vitro and in A2780 cells. Materials and methods. Chemicals. C/ jplatin was rate of removal oftotal platinum-DNA adducts (22).

In order to determine the nature of the cytotoxic lesion (s) formed by the antitumour drugs cisplatin and carboplatln, a comparative study was made of bifunctional DNA-adduct formation by these drugs. The kinetics of bifunctional cisplatin adduct formation were studied with DNA in vitro and in cultured Chinese hamster ovary (CHO) cells. Platinum-based chemotherapies cause the formation of DNA adducts and have profound effects on DNA. This study measured cis- diamminedichloroplatinum II (cisplatin) DNA adducts by 32 P-radiolabeling DNA, enzymatically digesting radiolabeled DNA, separating the formed adducts on two-dimensional thin-layer chromatography, and quantitating the adducts with autoradiography and densitometry.

It is now accepted that spe-cific recognition of DNA–cisplatin adducts by nuclear proteins, especially from the HMG-domain family, inhibits Cisplatin, a DNA-crosslinking agent, is able to suppress DNA synthesis by conforming DNA adducts in cancer cells. Cisplatin , CAS 15663-27-1 Pack Size At high enzyme concentrations (2.5–25-fold excess over primer-template), pol β did not differentiate between cisplatin and oxaliplatin adducts for any DNA substrate tested (data not shown); therefore data are presented for cisplatin-damaged templates only.

Transplatin, (an isomer of cisplatin that has the chlorine atoms opposite each other, rather than on the same side) also forms adducts with DNA, but mostly mono-adducts. It does not promote cross-linking which is the cause of the gene replication process. The cisplatin molecule binds with a protein on one side and the DNA molecule on the other.

As noted, HNE-adducts are been reported in AD brain (7,8,57).

When a DNA sample was dialysed against 0.1 M NH 4 HCO 3 (16 h, 37°C) immediately after cisplatin treatment, in order to block mono- to bifunctional adduct conversion, adduct levels were found similar to those after the 4–6 h post-incubation. From this it is clear that the high values reported earlier for bifunctional cisplatin adducts in

Radiosensitization of DNA by Cisplatin Adducts Results from an Increase in the Rate Constant for the Reaction with Hydrated Electrons and Formation of PtI. The Journal of Physical Chemistry B 2015 , 119 (30) , 9496-9500. Since Pt-GG does not appear to block DNA replication more than 8-oxo-G in mammalian cells, the cytotoxicity of the drug cisplatin that produces the cisplatin-DNA adduct is likely attributed to other causes, such as inter-strand cisplatin-DNA adducts that are more potent for stalling DNA replication.

Cisplatin is one of the most effective anticancer agents widely used in the treatment of solid tumors. It is generally considered as a cytotoxic drug which kills cancer cells by damaging DNA and inhibiting DNA synthesis.

Carboplatin is a DNA synthesis inhibitor. DNA synthesis is the natural or artificial creation of deoxyribonucleic acid (DNA) molecules. Carboplatin inhibits DNA synthesis by binding to DNA and interfering with repair mechanism.
