Abstract

Abstract Anti-estrogenic cyclopropyl analogs such as 1,1-dichlorocis-2,3-diphenylcyclopropane, when administered to a subject function as anti-tumor agents to prevent the development of estrogen-dependent tumors in the subject and substantially arrest the growth and metastatic involvement of existing estrogen-dependent tumors in the subject. Further, the anti-estrogenic cyclopropyl analogs may be used as anti-estrogenic agents and as fertility agents in the treatment of female infertility. The cyclopropyl analogs useful as anti-tumor, anti-estrogenic and female fertility agents have the general structure <IMAGE> wherein: X is a halogen or hydrogen atom; R1 is a hydrogen atom, an alkyl group containing from 1 to about 3 carbon atoms, a monocyclic group, a hydroxy substituted monocyclic group, an alkoxy substituted monocyclic group in which the alkyl substituent contains from 1 to about 3 carbon atoms or an acetoxy substituted monocyclic group; R2 is a hydrogen atom, an acetate group, a hydroxyl group, an alkoxy group in which the alkyl substituent contains from 1 to about 3 carbon atoms, a beta-dialkylaminoethoxy group wherein the alkyl substituent contains from 1 to about 6 carbon atoms, a beta-monoaminoheterocycloethoxy group, or pharmaceutically acceptable salts thereof; R3 is a hydrogen atom, an acetate group, a hydroxyl group, or an alkoxy group in which the alkyl substituent contains from 1 to about 3 carbon atoms; R4 is a hydrogen atom, or an alkyl group containing from 1 to about 3 carbon atoms; and the wavy lines ( ) in the structure indicate that the anti-tumor agent can be the cis- or trans-isomers.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 68 words
A method for inducing anti-estrogenic activity in a mammal in need of such activity comprising administering to the mammal an anti-estrogenically effective, non-toxic dosage of the compound having the structure ##STR11## wherein: X is chlorine; R 1 is a hydrogen atom; R 2 is a hydrogen atom; R 3 is a hydrogen atom; R 4 is a hydrogen atom; and the compound is characterized by a cis structure.
Claim 2
Independent Claim 68 words
A method for inducing anti-estrogenic activity in a mammal in need of such activity comprising administering to the mammal an anti-estrogenically effective, non-toxic dosage of the compound having the structure ##STR11## wherein: X is chlorine; R 1 is a hydrogen atom; R 2 is a hydrogen atom; R 3 is a hydrogen atom; R 4 is a hydrogen atom; and the compound is characterized by a cis structure.
Claim 3
Independent Claim 94 words
A method for preventing the development of estrogen-dependent tumors in a subject in need of such therapy or to substantially arrest the growth and metastatic involvement of existing estrogen-dependent tumors in a subject in need of such therapy, the method comprising administering to the subject a therapeutically effective, non-toxic dosage of the compound having the structure ##STR12## wherein: X is chlorine; R 1 is a hydrogen atom; R 2 is a hydrogen atom; R 3 is a hydrogen atom; R 4 is a hydrogen atom; and the compound is characterized by a cis structure.
Claim 4
Independent Claim 94 words
A method for preventing the development of estrogen-dependent tumors in a subject in need of such therapy or to substantially arrest the growth and metastatic involvement of existing estrogen-dependent tumors in a subject in need of such therapy, the method comprising administering to the subject a therapeutically effective, non-toxic dosage of the compound having the structure ##STR12## wherein: X is chlorine; R 1 is a hydrogen atom; R 2 is a hydrogen atom; R 3 is a hydrogen atom; R 4 is a hydrogen atom; and the compound is characterized by a cis structure.
