Recent developments in tubulin polymerization inhibitors: An overview

Area of Science:

• Biochemistry
• Medicinal Chemistry
• Cell Biology

Background:

• Microtubules, composed of α- and β-tubulins, are crucial for cell division (mitosis).
• Disrupting microtubule dynamics can halt cell cycle progression and lead to abnormal mitotic spindles.
• Microtubules are validated targets for anticancer drug development, with natural products like paclitaxel being prime examples.

Purpose of the Study:

• To review recent advancements in synthetically derived chemical compounds as potent tubulin polymerization inhibitors.
• To provide insights into synthetic methodologies and structure-activity relationship (SAR) studies of these inhibitors.
• To facilitate the design and synthesis of novel anticancer agents targeting tubulin.

Main Methods:

• Literature review of recently reported synthetic tubulin polymerization inhibitors.
• Analysis of synthetic routes for accessing these compounds.
• Summary of SAR studies to understand key structural features for inhibitory activity.
