  Cryptocaryols A and B: Total Syntheses, Stereochemical Revision, Structure Elucidation, and Structure–Activity Relationship

  摘要：

  The first total syntheses and structural elucidation of cryptocaryol A and ayptocaryol B were achieved in 23 and 25 linear steps, respectively. The synthesis relied on the use Of a key pseudo-C, symmetric pentaol intermediate, which in a stereochemically divergent manner was converted into either enantiomer as well as diastereomers. This synthetic effort enabled the first structure-activity relationships of this class of PDCD4 stabilizing natural products.

  The synthetic cryptocaryols A and B and a series of their analogues have been evaluated for their cytotoxicity and their ability to stabilize the tumor suppressor PDCD4. Cytotoxicities in the 3 to 30 mu M range were found. Both the cytotoxicity and PDCD4 stabilizing ability were tolerant of large stereochemical changes to the molecule. Co-dosing studies with cryptocaryols A and B and several known cancer drugs showed no measuable enhancement in cancer drug cytotoxicity.
