Synthesis, in vitro progesterone receptors affinity of gadolinium containing mifepristone conjugates and estimation of binding sites in human breast cancer cells

Bioorg Med Chem. 2010 Mar 1;18(5):1891-8. doi: 10.1016/j.bmc.2010.01.048. Epub 2010 Jan 25.

Abstract

Novel gadolinium-based mifepristone conjugates were synthesised using various synthetic routes. Moderate antiprogestagenic activity of the new conjugates was observed in human breast cancer cells (T47-D cells) using AP (alkaline phosphatase) assay. The amount of incorporated Gd determined by inductively coupled plasma mass spectroscopy (ICPMS) indicates the number of binding sites per cell. These conjugates might be important compounds to develop receptor-targeted MRI contrast agents as well as other anti-breast cancer therapeutics.
