Answer

Antineoplastics, Platinum Analog

Platinum compounds inhibit cell growth and proliferation.

Carboplatin

Analog of cisplatin. This is a heavy metal coordination complex that exerts its cytotoxic effect by platination of DNA, a mechanism analogous to alkylation, leading to interstrand and intrastrand DNA crosslinks and inhibition of DNA replication. Binds to protein and other compounds containing SH group. Cytotoxicity can occur at any stage of the cell cycle, but cell is most vulnerable to action of these drugs in G1 and S phase.

Cisplatin

Cisplatin is a platinum-containing compound that exerts an antineoplastic effect by covalently binding to DNA, with preferential binding to N-7 position of guanine and adenosine. It can react with 2 different sites on DNA to produce cross-links. The platinum complex also can bind to nucleus and cytoplasmic protein.

Oxaliplatin (Eloxatin)

Cisplatin is a platinum-containing compound that exerts an antineoplastic effect by covalently binding to DNA, with preferential binding to N-7 position of guanine and adenosine. It can react with 2 different sites on DNA to produce cross-links. The platinum complex also can bind to nucleus and cytoplasmic protein.
