  Synthesis and structure revision of tyroscherin, and bioactivities of its stereoisomers against IGF-1-dependent tumor cells

  摘要：

  Synthesis of the proposed structure of tyroscherin, a growth inhibitor of IGF-1 -dependent cancer cells, was succeeded by one-pot Julia Coupling. However, spectral data of the synthetic compound were not identical with those of natural tyroscherin. The stereochemistry of tyroscherin is revised to be 2S,3R,8R,10R by syntheses of stereoisomers. Synthetic tyroscherin showed more potent activity than its stereoisomers against IGF-1-dependent cancer cells. (C) 2009 Elsevier Ltd. All rights reserved.
