A class of substituted benzylnaphthylene compounds of the structurewhere R1 and R2 are independently hydrogen, alkyl of one to six carbon atoms, acyl of two to six carbon atoms, or phenacyl; X is -(CH2)1-6; Y is absent or is selected from 1,4-piperazinylene; ureido; N-(lower alkyl)ureido; N'-(lower alkyl)ureido; or N, N'-(di-lower alkyl ureido; and Z is 1-, 2- or 3-pyrrolidinyl; 1-, 2-, or 3-[1-(lower alkyl) pyrrolidinyl]; 1- 2-, 3- or 4-piperidinyl; 1-, 2-, 3- or 4-[1-lower alkyl)piperidinyl]; N,N-dialkyl; 1-azepinyl; 1- or 2-naphthylamino, 4-morpholinyl, dimethyl-4-morpholinyl, 3-azaspiro[5.5]undecan-3-yl; pyrrolidinon-1-yl; unsubstituted phenyl; or phenyl substituted with acyl of two to four carbon atoms, alkyl of one to four carbon atoms, halo, or alkoxy of one to four carbon atoms; with the proviso that n is not 2 or 3 when Z is 1-pyrrolidinyl, 1-piperidinyl, 1-azepinyl, 4-morpholinyl, N,N-dimethylamino or N,N-diethylamino; are selective estrogen receptor modulators useful in the prophylaxis or treatment of breast cancer. |
