Xanthone Derivatives in the Fight against Glioblastoma and Other Cancers

Xanthone derivatives constitute an interesting and widely studied group of compounds, both in terms of the activity of naturally occurring plant ingredients and as a scaffold with high biological activity potential for medicinal chemists. This group of compounds has already been the subject of reviews. However, our purpose was to prepare a publication for medicinal chemists to have a clear overview of anticancer activity, particularly in central nervous system cancer glioblastoma, and to be able to compare their new achievements to the anticancer activity that has already been found in this group. An integral part of the work is a tabular summary of the literature results of antineoplastic activity (e.g., IC50 values) for xanthone derivatives in various types of in vitro viability assays.
