SR1001 has been used as retinoic-acid receptor (RAR)-related orphan nuclear receptor gamma (RORγt) inhibitor to study its effects on interleukin 17 (IL-17) expression in itch cells , as a RAR-related orphan receptor alpha (RORα)- inhibitor to study its effects on RORα-dependent transcription of glucose-6-phosphatase (G6Pase) .
SR1001 has been used for inhibiting retinoid-related orphan receptor-γ t (RORγT) activation in Itch−/− mice.
Biochem/physiol Actions
SR1001 is a RORα/RORγt antagonist with no activity at LXR or RORβ; suppressor of TH17 cell differentiation and autoimmunity.
SR1001 is an antagonist of the nuclear retinoic acid receptor-related orphan receptors RORα and RORγt with no activity at LXR or RORβ. RORα and RORγt are essential for the development of TH17 cells, T-helper cells that produce interleukin-17 and have recently been shown to have pathological roles in various autoimmune diseases. SR1001 binds to the ligand-binding domain of RORα and RORγt to decrease affinity of the receptor for coactivators and increse affinity for co-repressors. It inhibited the differentiation and function of TH17 cells and suppressed the clinical severity of a mouse model of multiple sclerosis.

Dysregulated expression of interleukin 17 (IL-17) in the colonic mucosa is associated with colonic inflammation and cancer. However, the cell-intrinsic molecular mechanisms by which IL-17 expression is regulated remain unclear. We found that deficiency in the ubiquitin ligase Itch led

Fasting hormones activate the cAMP/PKA signaling pathway and stimulate expression of hepatic gluconeogenic enzymes including glucose-6-phosphatase (G6Pase). Previously it was shown that steroid receptor coactivator 2 (SRC-2) knock-out mice exhibit fasting hypoglycemia and that SRC-2 coactivates RAR-related orphan receptor alpha
