Polypharmacology of Approved Anticancer Drugs

Area of Science:

• Oncology
• Pharmacology
• Drug Discovery

Background:

• Current oncology drug discovery focuses on highly selective molecules targeting single or few related drug targets.
• However, data suggests approved anticancer agents interact with numerous proteins, indicating broader mechanisms of action.

Purpose of the Study:

• To review and systematize information on the targets of anticancer drugs.
• To revise the potential mechanisms of action for these agents.
• To explore the role of polypharmacology in cancer treatment.

Main Methods:

• Literature review of existing bioassay data.
• Systematization of information on anticancer drug targets.
• Analysis of drug mechanisms of action.

Main Results:

• Approved anticancer agents exhibit polypharmacology, targeting multiple proteins with diverse functions.
• The efficacy of current antineoplastic agents is linked to the modulation of multiple cellular mechanisms.

Conclusions:

• Anticancer drug efficacy is achieved through the modulation of multiple cellular pathways, not just single targets.
• Understanding polypharmacology is crucial for future oncology drug development.
