Non-Steroidal Steroid Receptor Modulators

The last ten years much attention has been focused on the finding of non-steroidal ligands for steroidal nuclear receptors for reasons such as diminishing cross-reactivity to eliminate side effect profiles, changing physicochemical properties which might cause different tissue distribution profiles and altering binding modes which influence the binding of cofactors. Compounds with a selective functionality profile are referred to as selective nuclear receptor modulators (e.g., SARMs or SPRMs). In the following paragraphs nonsteroidal ligands which have full or partial agonistic activity will be described for the following receptors: PR, GR, AR, LXR and FXR.
