Cover Picture: Total Synthesis and Configurational Assignment of (−)-Dictyostatin, a Microtubule-Stabilizing Macrolide of Marine Sponge Origin / Total Synthesis of (−)-Dictyostatin: Confirmation of Relative and Absolute Configurations (Angew. Chem. Int. Ed. 35/2004)

43_35/2004Sponging off nature is a reliable way to find promising drug leads: (−)-Dictyostatin, which was isolated from the marine sponge Corallistidae, is a novel microtubule-stabilizing agent that could be useful against multidrug-resistant tumors. In their Communications on pages 4629 ff. and 4634 ff., the groups of I. Paterson and D. P. Curran describe the total synthesis of this challenging target, thus establishing unequivocally the relative and absolute configuration of the macrolactone and opening the way to useful amounts of the drug and designed analogues. The Photo of the sponge was provided by Harbor Branch Oceanographic Institution.
