The steroid hormone receptors are a subset of this superfamily whose natural ligands are typically comprised of 10 endogenous steroids such as estradiol, progesterone, and cortisol. Man-made ligands to these receptors play an important role in human health and, of these receptors, the glucocorticoid receptor has an essential role in regulating human physiology and immune response. Steroids that interact with the glucocorticoid receptor have been shown to be potent antfinflammatory agents. The present invention is directed to a 15 novel class of compounds that are selective glucocorticoid receptor modulators that have potent ani-inflammatory and immunosupresive activity and possess advantages over steroidal glucocorticoid ligands with respect to side effects, efficacy, toxicity and/or metabolism. 20 SUMMARY OF THE INVENTION The present invention encompasses compounds of Formula I: R1 6 1 0 (R -2 M Y2 R7 r D 3 I R K XR10 J ' (R1 1)0.3 25 1 or pharmaceutically acceptable salts or hydrates thereof, which are useful as selective glucocorticoid receptor ligands for treating a variety of autoimmune and inflammatory diseases or conditions.
