Abstract
Nitrogen-containing heterocycles play a central role in medicinal chemistry, particularly in the development of anticancer therapeutics. Among these, the indole nucleus has attracted sustained interest owing to its structural versatility, favorable physicochemical properties, and ability to interact with diverse biological targets. A wide range of indole-based compounds, including natural products, semi-synthetic analogues, and fully synthetic derivatives, have demonstrated significant antiproliferative activity across multiple cancer models. The anticancer effects of indole derivatives arise from their capacity to modulate key molecular pathways involved in tumor growth and survival, such as kinase-mediated signaling, epigenetic regulation, DNA-processing enzymes, and microtubule dynamics. Clinically approved drugs such as vincristine and vinblastine exemplify the therapeutic relevance of this scaffold and continue to inspire the design of next-generation indole analogues with improved selectivity and pharmacokinetic performance. This review highlights recent advances in indole-based anticancer agents, emphasizing their mechanisms of action, structural diversity, and future potential in oncology drug discovery.
