Abstract
A phenol derivative of the formula EQU NU--A--X--R.sup.1 PA0 wherein NU is a defined bis-phenolic nucleus including a hydroxyphenyl-hydroxynaphthyl; hydroxyphenyl-hydroxyindanyl, hydroxyphenyl-hydroxybenzothienyl or di-hydroxyphenyl-ethylene or vinylene nucleus; PA0 wherein A is alkylene, alkenylene or alkynylene which may be interrupted by phenylene or other linkages, PA0 wherein R.sup.1 is hydrogen, or alkyl, alkenyl, cycloalkyl, halogenoalkyl, aryl or arylalkyl, or R.sup.1 is joined to R.sup.2, and wherein X is --CONR.sup.2 --, --CSNR.sup.2 --, --NR.sup.12 CO--, --NR.sup.12 CS--, --NR.sup.12 CONR.sup.2 --, ##STR1## --SO.sub.2 NR.sup.2 -- or --CO--, or, when R.sup.1 is not hydrogen, is --NR.sup.12 COO--, --S--, --SO-- or --SO.sub.2 --, wherein R.sup.2 is hydrogen or alkyl, or R.sup.1 and R.sup.2 together form alkylene; PA0 wherein R.sup.12 is hydrogen or alkyl, and wherein R.sup.22 is hydrogen, cyano or nitro; or a salt thereof when appropriate. The compounds possess antioestrogenic activity and may be used for the treatment of hormone-dependent breast tumors or of anovulatory infertility.
