Organometallic complexes of estrogens and their application to the determination of hormone receptors

摘要

The present invention relates to an estrogen complex which consists of an estrogen or an estrogen derivative complexed with an organometallic compound containing at least one free carbonyl ligand, the said estrogen complex containing at least one free hydroxyl radical and no free phenolic hydroxyl radical in the -position to the site where the organometallic compound is attached.PPThe complexes according to the invention are useful for the determination of hormone receptors.
