The first titanocenyl dichloride moiety vectorised by a selective estrogen receptor modulator (SERM).: Synthesis and preliminary biochemical behaviour

The synthesis of 4'. a titanocene derivative of the anticancer drug tamoxifen is presented together with its biochemical properties. Compound 4' is prepared by a McMurry coupling followed by a ligand exchange. Compound 4' reveals an unexpected proliferative effect on the hormone-dependent cell line MCF7. Surprisingly this effect is also observed with Cp2TiCl2 alone. (C) 2002 Elsevier Science B.V. All rights reserved.
