As part of our program to develop new estrogen receptor (ER) probes we have explored approaches that would lead to agents capable of incorporating single photon- or positron-emitting radionuclides. Because these materials impose different experimental constraints compared to conventional functional groups, new synthetic strategies are necessary. While the ultimate products still need to retain high affinity and selectivity for the target protein, overall yields and reaction times are not critical until the steps involving the radionuclide. Our recent work has focused on methods for introducing either the Re/Tc-nuclides for therapy/SPECT imaging or F-18 for PET imaging. In this presentation we will describe the strategy, synthetic methods, and biological studies leading to the preliminary labeling and imaging efforts.
