SR 1078 is a selective agonist of RORα and RORγ that stimulates ROR transcriptional activity in HEK293 cell reporter assays.

sr1078 is an agonist of retinoic acid receptor-related orphan receptor (ror) rorα and rorγ with ic50 values of both 1-3 μm [1].rorα and rorγ are two members of nuclear receptor superfamily, which possesses a highly conserved dna-binding and a ligand-binding domain. these two receptors are considered to play important roles in the regulation of metabolism and the function of immune system [1].sr1078 is a selective rorα and rorγ agonist, which activate rorα and rorγ directed transcription via inducing conformational changes [1].sr1078 selectively targets on rorα and rorγ as an agonist but not on lxr and fxr [1]. it was shown that sr1078 was able to stimulate ror activity and subsequent ror-directed mrna expression. when hepg2 cells were treated with sr1078 for 24h, the ror directed reporter gene fg21 mrna level was increased by 3-fold, while another reporter gene g6pase was increased by 2-fold [1].in mouse model, i.p. injection of 10 mg/kg sr1078 for 1 hr resulted in 3.6 μm plasma concentration., and after 8 hr the concentration still sustained at 800 nm. i.p. injection of 10 mg/kg sr1078 for 2 hr resulted in significantly increased level of mrna of reporter gene g6pase and fg21 [1].
