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