A comprehensive review of anticancer heterocyclic natural products has identified several promising drug candidates with significant potential for treating various cancer types. Researchers from India conducted an in-depth analysis of three heterocycle families—furan, quinoline, and indole—examining their anticancer bioactivities and synthetic approaches.
The study, published in Current Pharmaceutical Analysis, highlighted six notable drug candidates with sub-micromolar half-maximal inhibitory concentrations: viridin, muricatetrocin B, jimenezin, pancrastatin, quinocarcin, and aleutiananmine. These compounds demonstrate strong interactions with critical biological targets such as nucleic acids, enzymes, and receptors.
Despite the promising results, researchers identified significant challenges in current synthetic methods. The majority of these natural products require multiple synthesis steps with low yield, making large-scale production and clinical trials challenging. Co-author Tirth Chauhan emphasized that blood concentrations of these potential drugs can reach low micromolar ranges, underscoring the importance of efficient production methods.
The research suggests emerging technologies like artificial intelligence, database-directed reaction planning, continuous-flow chemistry, and electrochemistry could revolutionize drug synthesis. Corresponding author Manan Shah stressed the importance of minimizing heavy metal and noble metal catalysis to promote green chemistry principles.
A key recommendation from the study is exploring modular synthesis techniques to transform natural compounds into nature-like pharmaceutical products. By adjusting absorption, distribution, metabolism, and excretion (ADME) properties, researchers hope to develop more effective anticancer treatments with improved manufacturing processes.
