Abstract:
To circumvent antiandrogen resistance in prostate cancer, antiandrogens effective for both the androgen receptor (AR) and AR mutants are required. The AR antagonists in this study originate from previous findings, which showed that subtle differences in substitution pattern lead to a conformational change that alters the ligand activity, rendering an agonist to an antagonist. We have identified small yet potent tropanol-based ligands possessing significant antiandrogenic activity with both wild-type AR and the two most common AR ligand binding domain (LBD) mutants.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
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.
