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; R.sub.1 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; R.sub.2 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; R.sub.3 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; R.sub.4 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.
抗雌激素环丙基类似物,如1,1-二氯顺-2,3-二苯基环丙烷,当用于患者时,可作为抗肿瘤剂,预防患者发生雌激素依赖性肿瘤,并且显著抑制患者现有的雌激素依赖性肿瘤的生长和转移。此外,抗雌激素环丙基类似物可用作抗雌激素剂和女性不孕症治疗中的生育剂。作为抗肿瘤、抗雌激素和女性生育剂有用的环丙基类似物具有以下通用结构:##STR1##其中:X是卤素或氢原子;R.sub.1是氢原子、含有1至约3个碳原子的烷基、单环基、羟基取代的单环基、烷氧基取代的单环基,其中烷基取代物含有1至约3个碳原子,或乙酰氧基取代的单环基;R.sub.2是氢原子、乙酸酯基、羟基、烷氧基,其中烷基取代物含有1至约3个碳原子、β-二烷基氨基乙氧基,其中烷基取代物含有1至约6个碳原子、β-单氨基杂环环丙氧基,或其药学上可接受的盐;R.sub.3是氢原子、乙酸酯基、羟基或烷氧基,其中烷基取代物含有1至约3个碳原子;R.sub.4是氢原子或含有1至约3个碳原子的烷基;结构中的波浪线()表示抗肿瘤剂可以是顺式异构体或反式异构体。
