Open Access Abstract Rheumatoid arthritis RA is a chronic inflammatory disease that produces synovial proliferation and joint erosions. The pathologic lesions of RA are driven through the production of inflammatory mediators in the synovium mediated in part by the transcription factor NF-kB. We have identified a non-steroidal estrogen receptor ligand WAY-169916 that selectively inhibits NF-kB transcriptional activity but is devoid of conventional estrogenic activity. The activity of WAY-169916 was monitored in two models of arthritis the HLA-B27 transgenic rat and the Lewis rat adjuvant-induced model after daily oral administration. In both models a near complete reversal in hindpaw scores was observed as well as marked improvements
