An estrogen/antiestrogen-porphyrin conjugate, their composition and methods for their use are claimed. The active compounds of the invention are conjugates consisting of an estrogen or anti estrogen portion, tether or linker portion and a porphyrin portion. The method of invention exploits an active process that involves strong and specific interactions between nuclear receptor and its cognate ligand.

beta-vinyl moiety was established by X-ray crystallography. The final product and several analogues, 11 beta-ethyl-, -vinyl-, and (hydroxyethyl)estradiols (11, 5, and 12), were evaluated for their estrogen receptor binding affinity. The results indicate that the target compound and several 11 beta-substituted analogues possess relative binding affinities greater than of estradiol and its 16 alpha-fluorinated
