Synthesis ofN-(9H-Xanthen-9-yl)aminoalkanamide andN-(9H-Thioxanthen-9-yl)aminoalkanamide Derivatives and theirin vitro Evaluation as Potential Intercalators and Antitumor Drugs
A series of new N‐(9H‐xanthen‐9‐yl)aminoalkanamide and N‐(9H‐thio‐xanthen‐9‐yl)aminoalkanamidederivatives was synthesized and evaluated as potentialintercalators by measuring their DNA binding affinity. They were also tested for cytotoxic activity against L1210. The results suggest that the cytotoxicity of these molecules was not due to an intercalating mechanism.

In further pursuing our search for potent and selective aromataseinhibitors, a new series of molecules was designed and synthesized, exploring possible structural modifications of a previously identified xanthone scaffold. Among them, highly potent compounds, with inhibitory activity in the low nanomolar range, were found. In particular, substitution of the heterocyclic oxygen atom in the xanthone
