cisplatin reaction with dna

In genetics crosslinking of dna occurs when various exogenous or endogenous agents react with two nucleotides of dna forming a covalent linkage between them this crosslink can occur within the same strand intrastrand or between opposite strands of double stranded dna interstrand.

Cisplatin reaction with dna. Cisplatin is similar to the bifunctional alkylating agents. Hypersensitivity to cisplatin or to any of the excipients listed in section 6 1. The aquation of carboplatin which is thought to produce the active species occurs at a slower rate than in the case of cisplatin. This effect is apparently cell cycle nonspecific.

In the present study 3d printed porous ti 6 al 4 v implants were fabricated and loaded with cisplatin using a plga peg plga hydrogel as the vehicle. The table lists initial rate data for four experiments in which the reaction was run at ph 7 0 and 25 c but with different initial concentrations of cisplatin. Cisplatin may be inadvisable if you have a history of severe allergic reaction to cisplatin carboplatin other platinum containing formulations or mannitol. Cisplatin may give allergic reactions in some patients.

The rate law and reaction order of the hydrolysis of cisplatin are determined from experimental data such as those displayed in ta ble pageindex 1. It covalently binds to dna and disrupts dna function. Cisplatin treatment has been associated with several toxic side effects including nephrotoxicity de jongh van veen et al 2003. This reaction results in the formation of positively charged platinum complexes that react with the nucleophilic sites on dna.

The anti tumour effect and biosafety of the cisplatin hydrogel loaded implants were evaluated in the context of osteosarcoma in vitro and in vivo because of the potential cytotoxicity of chemotherapeutic agents on osteoblasts the adverse effects. Use is contraindicated in those patients with a history of allergic reaction to cisplatin or other platinum containing compounds or any component of the formulation. As a 501 c 6 organization the sgo contributes to the advancement of women s cancer care by encouraging research providing education raising standards of practice advocating for patients and members and. The society of gynecologic oncology sgo is the premier medical specialty society for health care professionals trained in the comprehensive management of gynecologic cancers.

Cisplatin may give allergic reactions in some patients. Do not receive any kind of immunization or vaccination without your doctor s approval while taking cisplatin.
