Synthesis and structure-activity studies of side-chain derivatized arylhydantoins for investigation as androgen
1Department of Radiology, The University of Michigan Medical School, Ann Arhor 48109-0552, USA. mvandort@umich.edu
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.

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
