Summarize the cellular mechanisms of action, structure-activity relationships, and recent synthetic and delivery advances for anthracycline chemotherapy drugs.
Reviewed empirical evidence on DNA topoisomerase II target identification and ternary complex formation mediated by doxorubicin and daunorubicin.
Evaluated functional consequences of specific anthracycline structural modifications, analogue synthesis strategies, and modern drug delivery mechanisms.
Anthracyclines act primarily by targeting DNA topoisomerase II, stabilizing a cleaved intermediate to form an inhibitory DNA-drug-enzyme ternary complex.
Intercalation alone is insufficient for topoisomerase II poisoning; eliminating 4-methoxy and 3'-amino substituents substantially enhances potency, while altering the 3' sugar substituent modulates DNA cleavage sequence specificity.
Structural optimization and improved delivery formulations enhance antitumor efficacy against resistant phenotypes while diminishing adverse off-target toxicities.
