Gem-Dichlorocyclopropanes (Analog II derivatives) which demonstrate antiproliferative activity toward MCF-7 cells, in vitro and are generally not reversed by estradiol or having intrinsic estrogenicity (except the hydroxyphenyl derivative Compound 30). In general the cyclopropane compounds have the formula: ##STR1## or any pharmaceutically acceptable salt thereof. X is selected from a group consisting of hydrogen and halogen atoms. The group R.sub.1 may he a hydrogen atom, an alkyl group, an acyl group, or an arylalkyl group. The group R.sub.2 may be a hydrogen atom, an unsubstituted aryl group or a substituted aryl group. The group R.sub.3 may be a hydrogen atom, an alkyl group, a cycloalkyl group, a substituted aryl group or an unsubstituted aryl group. The group R.sub.4 may be a hydrogen atom, an unsubstituted aryl group or a substituted aryl group. The R.sub.4 is absent when R.sub.3 is a cycloalkyl group having a first position carbon and a terminal position carbon bonded to the same carbon of the cyclopropane. Further, no more than any two of R.sub.2, R.sub.3 and R.sub.4 has an aryl group.

Gem-dichlorocyclopropanes as antitumor agents

Diphenylcyclopropyl analogs in which one or more of the phenyl rings includes alkoxy substituents including a dialkylaminoalkoxy group, an unsubstituted piperazine alkoxy group, a substituted piperazine alkoxy group, an unsubstituted piperidine alkoxy group, and a substituted piperidine alkoxy group, and which may have one or two alkyl groups bonded to the cyclopropane. The compounds are useful as antiestrogens and anti-tumor agents.

Diphenylcyclopropyl analogs

Diphenylcyclopropyl analogs in which one or more of the phenyl rings includes substituents comprising a hydroxy group, a hydrogen atom, an acetate group or a substituted or unsubstituted alkoxy group. The compounds are useful as antiestrogens and anti-tumor agents.

Diphenylcyclopropyl analogs in which one or more of the phenyl rings includes substituents comprising a hydroxy group, a hydrogen atom, an acetate group or a substituted or unsubstituted alkoxy group. The compounds are useful as antiestrogens and antitumor agents.

Triarylcyclopropane derivatives in which one or more of the aryl groups includes a hydroxy as a substituted or unsubstituted or alkoxy or side chain substituent. The compounds are useful as antiestrogens and anti-tumor agents.

Triarylcyclopropanes as antiestrogens and antitumor agents

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 ##STR1## wherein: X is a halogen or hydrogen atom;

Cyclopropyl analogs as anti-estrogenic, anti-tumor and female fertility

Estrogenic cyclopropyl analogs, when administered to a female subject, function as anti-fertility agents to prevent pregnancy in the subject. Further, the estrogenic cyclopropyl analogs may be used as estrogenic agents to produce an estrogenic response in a female subject. The estrogenic cyclopropyl analogs useful as estrogenic agents have the general structure: ##STR1## wherein: X is a halogen or hydrogen atom:
