Phenanthrene Alkaloids From Guatteria Olivacea as Topoisomerase II Inhibitors: Theoretical Insights and Cytotoxic Evaluation

open access: yesChemistrySelect, Volume 11, Issue 2, 15 January 2026.
Three phenanthrene alkaloids from Guatteria olivacea were studied by DFT, docking, MD, and cytotoxicity assays. All compounds showed stable binding to DNA–topoisomerase II and human serum albumin. Atherosperminine exhibited cytotoxic activity against four cancer cell lines, supporting its potential as a topoisomerase II inhibitor and anticancer ...
