Q

they’re cell cycle phase nonspecific compounds that transfer an alkyl group to the 7 nitrogen atom of guanine residues in one or both strands of DNA
they’re main effect is on DNA synthesis (S phase) with most cytotoxicity to rapidly proliferating cells (hair cells, GI tract cells, taste buds, and tumor cells)
all are electrophilic molecules that covalently modify nucleophilic molecules in cells
DNA is most important adduct (N7 and O6 of guanine) residues in one or both strands of DNA

Q

they’re a type of alkylating agent
they form a platinum coordination complex , which forms cross-links with DNA and inhibits DNA synthesis (S phase)
they’re used to treat testicular, bladder, lung, and ovarian carcinoma
adverse effects include nephrotoxicity
members include: cisplatin, carboplatin, and oxaliplatin

A

platinum analogs
