Title: Synthesis and screening of mono- and di-aryl technetium and rhenium metallocarboranes. A new class of probes for the estrogen receptor.

Authors: Causey PW, Besanger TR, Valliant JF.

Abstract: A series of mono and diaryl rhenium(I)-carborane derivatives were prepared using microwave heating and screened for their affinity for two isoforms of the estrogen receptor (ER). The rhenacarborane derivative [(RR'C 2B9H9)Re(CO)3](-) (R = p-PhOH, R' = H), which was generated by taking advantage of a recently discovered cage isomerization process, and the neutral nitrosated analogue [(RR'C2B9H9)Re(CO)2(NO)] (R = p-PhOH, R' = H) showed the highest affinities of the compounds screened. As a result, the (99m)Tc analogue of one of the leads was produced in high yield (84%) and specific activity in a manner that is suitable for routine production in support of future preclinical and molecular imaging studies.
