Synthesis, structural characterization and preliminary cancer cell line results for polymers derived from reaction of titanocene dichloride and various poly(ethylene glycols)

We describe the initial synthesis of DMSO and water-soluble titanocene polyethers through reaction of the titanocene dichloride and various poly(ethylene glycols) employing commercially available reactants. Infrared, proton NMR, and MALDI MS results are consistent with the titanocene-containing polyether structure. The materials are polymeric with chain lengths ranging from 1500 to 4. They exhibit good inhibition of a variety of cancer cell...
