Table 1. Main mechanism of action for eight chemotherapeutic drugs.

Drug Drug class Mechanism of action
Amsacrine Topoisomerase inhibitors DNA intercalation and inhibition of topoisomerase II, causing DNA double-strand breaks, cell cycle arrest, and cell death
Bleomycin Antitumor antibiotic Forms complexes with iron that reduce molecular oxygen to form free radicals which in turn cause DNA single- and double-strand breaks
Bortezomib Proteosome inhibitors Reversibly inhibits the 26S proteosome and inhibits nuclear factor (NF)-kappaB causing disruption of various cell signaling pathways, cell cycle arrest, and cell death.
Carmustine Alkylating agents Alkylates and cross-links DNA causing cell cycle arrest and cell death
Cisplatin Alkylating agents Alkylates and cross-links DNA causing cell cycle arrest and cell death
Etoposide Topoisomerase inhibitors Binds to and inhibits topoisomerase II causing an increase of DNA single- and double-strand breaks, cell cycle arrest, and cell death
Puromycin Aminonucleoside antibiotic Acts as analog of 3′ terminal end of aminoacyl-tRNA and incorporates itself into growing polypeptide chain causing premature termination and inhibition of protein synthesis
Silver NA Multi-faceted induction of apoptosis
