摘要

A phenol derivative of the formula NU-A-X-R1 wherein NU is a defined phenolic nucleus including a phenyl-hydroxynaphthyl; hydroxyphenyl-naphthyl; phenyl-hydroxyindanyl, phenyl-hydroxybenzothienyl or mono-hydroxyphenyl-ethylene or vinylene nucleus; wherein A is alkylene, alkenylene or alkynylene which may be interrupted by phenylene or other linkages, wherein R1 is hydrogen, or alkyl, alkenyl, alkynyl, cycloalkyl, halogenoalkyl, alkoxyalkyl, halogenoalkoxyalkyl, aryl or arylalkyl, or R1 is joined to R2, and wherein X is -CONR2+13, -CSNR2-, -NR12CO-, -NR12CS-, -NR12CONR2-, -SO2NR2-or -CO-, or, when R1 is not hydrogen, is -NR12COO-, -(PO)R213 , -S-, -SO-or -SO2-, wherein R2 is hydrogen or alkyl, or R1 and R2 together form alkylene; wherein R12 is hydrogen or alkyl, and wherein R22 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.
