摘要
A metallacycle-centered approach to the assembly of partially aromatic synthetic steroids was investigated as a means to prepare a boutique collection of unique steroidal agents. The synthesis and discovery of estra-1,3,5(10),6,8-pentaene-2,16 alpha-diol (VII) is described, along with structure activity relationships related to its cytotoxic properties. Overall, VII was found to have a GI(50) = 0.2 mu g/mL (similar to 800 nM) in MDA-MB-231 human breast cancer cells, be an efficacious estrogen receptor agonist with potency for ER beta > ER alpha (ER beta EC50 = 21 nM), possess selective affinity to the cdc-2-like kinase CLK4 (K-d = 350 nM), and be phenotypically related to paclitaxel by an unbiased panel assessment.
