  • Patent number: 4732904
    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.

  • Patent number: 4673692
    Abstract: A compound represented by the formula ##STR1## wherein R.sup.1 represents a hydroxyl group, an alkanoyloxy group or a group of the formula ##STR2## in which R.sup.2 represents a hydrogen atom or a lower alkyl group, and R.sup.3 represents a hydrogen atom, a lower alkyl group, an alkanoyl group, a phenyl group, a carbamoyl group or a thiocarbamoyl group, or a salt thereof.The said compound can be prepared by reacting a compound represented by the formula ##STR3## with a compound of the formulaNH.sub.2 --R.sup.1 (III)wherein R.sup.1 is as defined hereinabove, or a salt thereof, and as required, alkanoylating the resulting compound of formula (I) in which R.sup.1 represents a hydroxyl group or an amino group, and as required, converting the resulting compound of formula (I) in which R.sup.1 is the group ##STR4## into its salt, and is useful for the treatment of inflammation, pain or rheumatism.
