Radiobrominated triphenylethylenes as estrogen receptor binding radiopharmaceuticals
Abstract
Estrogen receptor binding radiopharmaceuticals have potential for use in the diagnosis and treatment of cancers of the female reproductive system. Tamoxifen is an antiestrogen derived from the triphenylethylene skeleton which is used in the treatment of mammary carcinoma. Hydroxytamoxifen is a metabolite of tamoxifen which binds tightly to the estrogen receptor. Two triphenylethylene derivatives based on the structure of hydroxytamoxifen have been prepared: 1-bromo-1-phenyl-2- (2-dimethylamino)-4-ethoxyphenyl -2-(4-hydroxyphenyl) ethene (1) where the ethyl group of hydroxytamoxifen has been replaced by a bromine, and 1-bromo-1-phenyl-2,2-(4-hydroxyphenyl) ethene (2) with a similar substitution and also lacking the aminoethoxy side chain believed to confer antiestrogenicity. Both 1 and 2 bind strongly to the estrogen receptor. 2 has been labeled with the Auger electron emitting nuclide Br-80m in moderate yields in high specific activity using either N-bromosuccinimide or N-bromophthalimide and shows promise as a potential radiotherapy agent.
