Abstract

Außerordentlich cytotoxisch sind die aus Meeresschwämmen isolierten Spongipyrane. Sie wirken gegen mehrere menschliche Krebszellinien, wobei das als erste Verbindung dieser Naturstoffklasse isolierte Spongistatin 1 am wirksamsten ist. Die erste Totalsynthese dieses Makrolids wurde nun abgeschlossen. Durch sie wird die von Kitagawa et al. vorgeschlagene relative und absolute Konfiguration bestätigt und nachgewiesen, daß Altohyrtin A und Spongistatin 1 identisch sind.
