Topic overview

Start with the big picture

The lesson organizes these agents by mechanism and connects each class to characteristic cell-cycle effects, clinical uses, and adverse effects. Vinca alkaloids inhibit microtubule polymerization, while taxanes stabilize microtubules; both lead to mitotic arrest but have differing toxicity patterns. Topoisomerase inhibitors include epipodophyllotoxins and camptothecins, with DNA damage and cell-cycle effects that differ by target. Other groups include anthracyclines, bleomycin, dactinomycin, and mitomycin C, which act through DNA intercalation, free radicals, or related mechanisms. L-asparaginase and pegaspargase deplete asparagine and have a key role in ALL. Recognizing hallmark toxicities—such as neuropathy, myelosuppression, pulmonary toxicity, and cardiomyopathy—supports safer comparison of these drug families.
