The present invention relates to novel Chartreusin analogues of formula (I), pharmaceutical compositions comprising the same and to their use for the treatment of cancer and other diseases.
Light on DNAintercalators: Molecular modeling and mutasynthesis were employed to rationally tailor the antitumoral agent chartreusin into a vinyl‐substituted derivative. Exposure with visible light dramatically improved antiproliferative activities owing to covalent binding with DNA and induction of apoptosis. The results hold promise for a more efficient chemotherapy, in particular for selectively

The first total synthesis of derhodinosylurdamycin A, an angucycline antitumor antibiotic, has been described. The synthesis features a Hauser annulation followed by pinacol coupling to construct the tetracyclic angular aglycon, a Stille coupling of glycal stannane and tetracyclic aryliodide followed by stereoselective reduction to afford the 2‐deoxy β‐C‐arylglycoside, and a late‐stage stereoselective
