Synthesis and biological evaluation of a spongistatin AB-spiroketal analogue.
The synthesis of a simplified analogue of the potent, cytotoxic tubulin-depolymerizing agent spongistatin 1, based on the AB spiroketal framework, is presented. The new structural analogue is an extension of a recently described spongistatin congener reported to disrupt microtubules in breast cancer cells in vitro and to alter the microtubule assembly reaction. Cytotoxicity data on the new structural analogue, as well as the parent congener, are reported. We found no significant cytotoxic or antitubulin activity with either compound.
