Abstract: Azido-, 4-nitro and 2,4-dinitrophenylhydrazones as well as 4,4'-dihydroxybenzophenone-hydrazone and other hydrazones are disclosed which have antiestrogenic activity useful in treating estrogen-requiring tumor cells. The described hydrazones bind to estrogen receptors in the cytoplasm of tumor cells. The azido-, 4-nitro- and 2,4-dinitro-phenyl branches of the molecules appear to bind to the receptors and prevent translocation of estrogenic information into the nucleus, thereby blocking the synthesis of necessary macromolecules such as proteins. Absence of geometric isomerization from antiestrogenic to estrogenic forms of the drug minimizes estrogenic side-effects.
