Tubulin-interactive natural products as anticancer agents

Area of Science:

• Pharmacology
• Natural Products Chemistry
• Oncology

Background:

• Natural products are a rich source of anticancer drugs.
• Tubulin dynamics are crucial for cell division and a validated target for cancer therapy.
• Many clinically used anticancer agents are derived from natural sources and target microtubules.

Purpose of the Study:

• To review the discovery, structures, and biological activities of natural products that modulate tubulin polymerization.
• To focus on compounds currently in clinical use or advanced clinical trials.
• To discuss challenges and future directions in tubulin-interactive natural product drug discovery.

Main Methods:

• Literature review of scientific publications and clinical trial data.
• Analysis of the mechanisms of action of natural products on tubulin.
• Categorization of compounds based on their effect on tubulin polymerization (inhibitors vs. promoters).

Main Results:

• Several classes of tubulin polymerization inhibitors are discussed, including vinca alkaloids, combretastatins, and eribulin.
• Major classes of tubulin polymerization promoters, such as taxanes and epothilones, are presented.
• Recent information on compounds in clinical use or advanced trials is emphasized.

Conclusions:

• Natural products targeting tubulin polymerization remain a vital area of anticancer drug discovery.
• Compounds like taxanes, epothilones, and eribulin demonstrate the clinical success of this strategy.
• Further research into novel tubulin-interactive natural products holds promise for future cancer therapies.
