Pathway-selective ligands for the estrogen receptor (ER) inhibit NF-kappaB-mediated inflammatory gene expression causing a reduction of cytokines, chemokines, adhesion molecules, and inflammatory enzymes. SAR development of a series of 4-(indazol-3-yl)phenols has led to the identification of WAY-169916 an orally active nonsteroidal ligand with the potential use in the treatment of rheumatoid arthritis without the classical proliferative effects associated with estrogens.

The diphenylsulfonyl sulfonamide scaffold represented by 1 (WAY-316606) are small molecule inhibitors of the secreted protein sFRP-1, an endogenous antagonist of the secreted glycoprotein Wnt. Modulators of the Wnt pathway have been proposed as anabolic agents for the treatment of osteoporosis or other bone-related disorders. Details of the structure-activity relationships and biological activity from the first structural class of this scaffold will be discussed.
