  Improved Synthesis of 6-epi-Dictyostatin and Antitumor Efficacy in Mice Bearing MDA-MB231 Human Breast Cancer Xenografts

  摘要：

  Structure-activity Studies centered oil the naturally occurring antitumor agent dictyostatin have recently identified several highly active epimers and analogues. From these compounds, 6-epi-dictyostatin was selected for scaleup preparation and evaluation in animals. Here we describe a new total synthesis that produced more than 30 mg of 6-epi-diclyostatin. The compound was found to have potent antitumor activity in SCID mice bearing MDA-MB231 human breast cancer xenografts.
