A Comprehensive Appraisal of Bisbenzylisoquinoline Alkaloids Isolated From Genus Cyclea for Anticancer Potential.

The pharmaceutical industry and academia are continuously searching for novel and effective anticancer lead compounds to ensure patient safety, provide a cure, and surpass all other obstacles. Given the indeterminate nature of cancer etiology, the importance of drugs capable of targeting multiple pathways cannot be overstated. Among naturally occurring compounds, bisbenzylisoquinoline (BBIQ) alkaloids, such as berberine, tetrandrine, chelidonine, and berbamine, have demonstrated significant anticancer potential by modulating diverse signaling pathways. Several of these compounds are currently in clinical trials, highlighting their relevance in cancer treatment. This review emphasizes the need for further investigation into the anticancer properties of BBIQ alkaloids, particularly those isolated from eight Cyclea species in India. With around 27 BBIQ alkaloids identified, these compounds hold promise, especially in combating multidrug resistance-a critical challenge in cancer therapy. Given the rising cancer incidence, these alkaloids warrant a deeper exploration of their therapeutic potential.
