We report the identification of substituted cis-bicyclo[3.3.0]oct-2-enes as small molecule agonists of subfamily V orphan nuclearreceptors (NR5A), liver receptor homolog-1 (LRH-1) and steroidogenicfactor-1 (SF-1). Using fluorescence resonance energy transfer (FRET)-based biochemical assays, compound 5a (GSK8470) was identified asa high-affinity ligand for LRH-1 and SF-1. In liver cells, 5a increasedthe expression of the LRH-1 target gene small heterodimer partner(SHP). Synthesis of analogues modified at three positions led to thedevelopment of compounds with functional selectivity between LRH-1and SF-1.
