In this figure cisplatin is bound to a 12 base pair double stranded DNA, creating a 49° bend with an overall helix bend of 78°. This bend in the DNA is crucial to cisplatin’s role as an anticancer drug. | In this figure cisplatin is bound to a 12 base pair double stranded DNA, creating a 49° bend with an overall helix bend of 78°.

Cisplatin, cis-PtCl2(NH3)2, is a chemotherapy drug, administered intravenously, used in the treatment of various types of cancer. This platinum-based drug acts in vivo by binding to two consecutive adjacent guanine bases in DNA. The binding of cisplatin bends the DNA, allowing for HMG-protein to bind. Once the HMG-protein is bound, de-stacking of the nucleotide base pairs occurs, which in turn kinks the DNA. With the HMG-protein bound to the DNA, the cell cannot properly repair the DNA, leading to apoptosis. | <scene name='Sandbox_Reserved_430/Cisplatin_intro/3'>Cisplatin</scene>, cis-PtCl2(NH3)2, is a chemotherapy drug, administered intravenously, used in the treatment of various types of cancer.
