42_48/2003Human DNA topoisomerase II is inhibited in vitro by acutissimin A, a flavano-ellagitannin, with an activity much higher than that of the clinically used antitumor drug etoposide. Acutissimin A is formed by a non-enzymatic, yet diastereoselective, condensation reaction occurring during the aging of red wine in oak barrels. S. Quideau et al. report its high-yielding semi-synthesis in their Communication on page 6012 ff.
