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 be 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(类比物II衍生物)在体外对MCF-7细胞表现出抗增殖活性,通常不会被雌二醇逆转或具有内在的雌激素作用(除羟基苯基衍生物化合物30外)。一般来说,环丙烷化合物的化学式为:##STR1##或其任何药学上可接受的盐。X选择自氢原子和卤素原子组成的一组。R.sub.1基团可以是氢原子,烷基,酰基或芳基烷基。R.sub.2基团可以是氢原子,未取代芳基或取代芳基。R.sub.3基团可以是氢原子,烷基,环烷基,取代芳基或未取代芳基。当R.sub.3是具有第一位置碳和终端位置碳与环丙烷的同一碳键合的环烷基时,R.sub.4缺失。此外,R.sub.2,R.sub.3和R.sub.4中最多有两个基团为芳基。
