SR3335 (also known as ML-176) is a novel and selective RORα inverse agonist with a Ki of 220 nM. SR3335 directly binds to RORα, but not other RORs, and functions as a selective partial inverse agonist of RORα in cell-based assays. Furthermore, SR3335 suppresses the expression of endogenous RORα target genes in HepG2 involved in hepatic gluconeogenesis including glucose-6-phosphatase and phosphoenolpyruvate carboxykinase. Pharmacokinetic studies indicate that SR3335 displays reasonable exposure following an ip injection into mice. We assess the ability of SR3335 to suppress gluconeogenesis in vivo using a diet-induced obesity (DIO) mouse model where the mice where treated with 15 mg/kg b.i.d., ip for 6 days followed by a pyruvate tolerance test. SR3335-treated mice displayed lower plasma glucose levels following the pyruvate challenge consistent with suppression of gluconeogenesis. Thus, SR3335 was identified as the first selective synthetic RORα inverse agonist, and this compound can be utilized as a chemical tool to probe the function of this receptor both in vitro and in vivo. Additionally, the data suggests that RORα inverse agonists may hold utility for suppression of elevated hepatic glucose production in type 2 diabetics.

SR3335 is a partial inverse agonist of RORα that is selective. It was clear that unlabeled SR3335 competed with RORα LBD in a dose-dependent manner in a biochemical factor ligand binding test with [3H]25-pillow as the binding label, with a Ki computed using the Cheng-Prusoff equation of 220 nM. While SR3335 had no influence on the activities of LXRα and RORγ, it considerably decreased the constitutive transactivation activity of RORα (IC50= 480 nM) (partial inverse agonist activity) in the cell co-transfection experiment of the chimeric receptor Gal4 DNA binding domain-NR ligand binding domain [1]. In HepG2 cells, endogenous RORα target genes involved in hepatic gluconeogenesis, such as phosphoenolpyruvyl acetonitrile (PEPCK) and potential-6-phosphatase (G6Pase), are inhibited by SR3335 [2]. Moreover, IL-25 and IL-33-induced ILC2 proliferation and IL-13 production can be externally burst by SR3335 [3].

After intraperitoneal injection, SR3335 exhibited a reasonable level of exposure in mice. Using the diet-induced exercise (DIO) animal paradigm, which involves treating mice with 15 mg/kg bid, ip for 6 days before testing them for pyruvate tolerance, the efficacy of SR3335 to suppress gluconeogenesis was assessed. Following pyruvate challenge, animals treated with SR3335 exhibited reduced transcript levels, which is consistent with transcriptional gluconeogenesis. Significantly, SR3335 (15 mg/kg/day; intraperitoneally for 7 days) therapy decreased rhinovirus (RV) infection in immature mice (6-day-old BALB/c mice) with lung ILC2s caused by RV[3].

For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.
