title: Synthesis of a novel class of cdc25A inhibitors from vitamin D3.
abstract: We have developed a novel class of cdc25A inhibitors by drastic modification of the hydrophobic and hydrophilic substructures of dysidiolide. The unsaturated derivative 3b strongly inhibited cdc25A (IC50 = 7.7 microM) and caused GI arrest of HL60 cells.
