Abstract

ERB-041 (2-(3-Fluoro-4-hydroxyphenyl)-7-vinyl-1,3 benzoxazol-5-ol) is a selective estrogen receptor-beta agonist with activity in rodent models of rheumatoid arthritis and endometriosis. Clinical trials for these diseases are underway: however, the role of estrogen receptor-beta in modulating pain associated with inflammation remains unknown. These studies demonstrate that acutely administered ERB-041 is anti-hyperalgesic in preclinical models of chemical-induced and acute inflammatory pain, thus suggesting that ERB-041 may be useful for modulating pain associated with some types of inflammation.
