Indole derivatives (2010-2020) as versatile tubulin inhibitors: synthesis and structure-activity relationships

Tubulin inhibitors are conjugates that interfere with the dynamic equilibrium of the polymerization and depolymerization of microtubules. Among all the reported conjugates, indole moiety is one of the most significant classes for the development of new drug candidates for cancer therapy. Due to their presence in a wide range of natural as well as synthetic antitubulin agents, indole has become a versatile scaffold in research, and various synthetic and semisynthetic indole-based antitubulin agents have been identified and reported. The present article focuses on the reported indole-based tubulin inhibitors of synthetic origin from last the decade. Synthesis, structure-activity relationships and biological activities of synthetic indole derivatives along with brief updates on their antitubulin activity are presented.

Automated summary

Indole-based tubulin inhibitors are compounds that disrupt the dynamic equilibrium of microtubule polymerization and depolymerization. Indole moiety is significant for developing new drug candidates for cancer therapy. Synthetic indole derivatives with antitubulin activity have been identified and reported in the past decade, showcasing diverse structure-activity relationships and biological activities.
