How does cisplatin work to stop cell division?

Cisplatin binds to two guanine bases in DNA, allowing a HMG protein to bind and insert a phenyl group into the DNA, which creates a kink in the DNA and causes the cell to die instead of divide.

If you look at the cisplatin there are two Cl- ions on the same side. These Cl- ions fall out and cisplatin binds to the nitrogen in two diferent guanine base pairs. This essentially stops the enzyme from taking apart the DNA, so the cell cannot divide.
