PROBLEM TO BE SOLVED: To provide non-steroidal estrogenic compounds with estrogenic and anti-estrogenic compound effects for treatment of estrogen deficiency-related disorders. SOLUTION: The compounds have formula (I) wherein, one of R a or R b is 'R e ; R e and 'R e are each OH, optionally independently etherified or esterified; X is N or -C(R 1 )-, wherein R 1 is H, a halogen, CN, an optionally substituted aryl, a 1-4C alkyl, a 2-4C alkenyl, a 2-4C alkynyl or the like, which alkyl, alkenyl, alkynyl and the like may optionally be substituted with one or a plurality of halogens; and Y is N or -C(R 2 )-, with the proviso that X and Y are not both N. These compounds are useful for estrogen receptor-related treatments in view of a desirable profile of activity for estrogen α and estrogen β receptors. COPYRIGHT: (C)2010,JPO&INPIT
