                            The invention provides non-steroidal estrogenic compounds with estrogenic and anti-estrogenic compounds effects for treatment of estrogen-deficiency related disorders, which compounds are having formula (I) wherein, one of R?a or Rb is 'Re; Re and 'Re¿ are OH, optionally independently etherified or esterified; X is N or -C(R1)-, wherein R1 is H, halogen, CN, optionally substituted aryl, (1C-4C)alkyl, (2C-4C)alkenyl, (2C-4C)alkynyl or (3C-6C)cycloalkyl, which alkyl, alkenyl, alkynyl and cycloalkyl groups can optionally be substituted with one or more halogens; Y is N or -C(R2)-, with the proviso that X and Y are not both N, wherein R2 has the same meaning as defined for R1; Z is C(R3,'R3)- or -C(R?4,'R4)-C(R5,`R5¿)-, wherein R?3, 'R3, R4, `R4, R5¿, and 'R5, independently are H, (1C-4C)alkyl, (2C-4C)alkenyl or (3C-6C) cycloalkyl, which alkyl, alkenyl and cycloalkyl groups can optionally be substituted with one or more halogens. These compounds are useful for estrogen-receptor related treatments in view of a desirable profile of activity for estrogen α and estrogen β receptors.
