Abstract

A series of arylhydantoin derivatives modeled after the antiandrogen RU 58841 was generated to identify potential candidates for development as androgen receptor (AR) radioligands. Side-chain modified derivatives of RU 58841, suitable for labeling with either carbon-11 or radiohalogens (fluorine-18, iodine-123), were synthesized and tested for their AR binding affinities. The N-(iodopropenyl) derivative 13 (Ki = 13 nM) is a potential candidate for development as a radioiodinated AR ligand.
