T0901317

Biological Activity

Description T0901317 is a potent and selective agonist of LXRα and LXRβ with Kd values of 7 nM and 22 nM, respectively.
Targets LXRα LXRβ        
IC50 7 nM 22 nM        

Protocol

Kinase experiment [1]:

Binding assays

The LXR ligand-binding domain was fused to the C-terminus of glutathione S-transferase (GST) and the resultant GST-LXR protein was expressed in Escherichia coli and purified on glutathione beads. Rhodamine-labeled peptide (10 nM; with amino acid sequence ILRKLLQE) was incubated on a shaker for 1 h with 400 nM GST-LXR and T0901317 in 100 μL of buffer (10 mM Hepes, 150 mM NaCl, 2 mM MgCl2, 5 mM DTT at pH 7.9) in a 96-well plate. Fluorescence polarization (mP) was measured on an LJL analyst (LJL Biosystems).

Cell experiment [1]:

Cell lines

HEK293 cells transfected with an expression plasmid for the human LXRα.

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

20 h.

Applications

T0901317 is a highly potent and selective nonsteroidal LXR ligand. T0901317 induces transcriptional activity of LXRα nearly 8-fold with EC50 value of 20 nM. T0901317 also transactivates chimeric Gal4-LXRα and Gal4-PXR (pregnane X receptor).

Animal experiment [1]:

Animal models

6- to 10-week-old C57BL/6 mice; 12- to 16-week-old Golden Syrian Hamsters.

Dosage form

Mice: 5, 50 mg/kg orally. Hamsters: 3, 10, 30 mg/kg orally.

Application

Oral treatment of C57BL/6 mice with T0901317 significantly increases the level of plasma triglycerides. In hamsters, T0901317 also increases plasma triglycerides. Also, T0901317 increases the expression of fatty acid metabolism-associated genes and hepatic fatty acid biosynthetic genes (ACC (2-fold), FAS (3-fold) and SCD-1 (9-fold)).

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

T0901317 is an agonist for multiple targets, which possesses EC50 values of 20 nM and 5 μM for LXRα and FXR, respectively. Furthermore, it is RORα and RORγ dual inverse agonist with estimated IC50 of 2.0 μM and 1.7 μM, respectively. [1, 2]

LXRs play central roles in cholesterol metabolism, which are nuclear receptors that regulate the metabolism of several important lipids, including cholesterol and bile acids. LXRs were first identified as orphan members of the nuclear receptor superfamily. Like LXRs, FXR was also initially thought as an orphan member of the nuclear receptor superfamily. But FXR was later identified as the physiological receptor for bile acids and shown to regulate a feedback loop for bile acid transport and synthesis as well as modulating additional functions in lipid metabolism. Retinoic acid receptor-related orphan receptors (RORs) are important in a variety of physiological processes including hepatic gluconeogenesis, lipid metabolism, circadian rhythm, and immunological functions. T0901317 inhibited transactivation activity of RORα and RORγ by direct binding with high affinity which led to the regulation of the receptor’s ability to interact with transcriptional cofactor proteins, but did not show inhibitory activity against RORβ. [1, 2]

A short synthetic rhodamine-labeled peptide was used to conduct a fluorescence polarization assay for T0901317 binding to LXRα. In this homogeneous biochemical assay, the greater the extent of rhodamine-peptide binding to LXR, the greater the extent of fluorescence polarization observed. The potency of T0901317 binding to LXRα was determined, which possessed EC50 of 20 nM. Adopting HEK293 cells transfected with Gal4 DBD-FXR ligand-binding-domain chimeric receptor along with Gal4-responsive luciferase reporter, T0901317 activated FXR with an EC50 of ~5 uM, which surpassed the potency of natural FXR ligand. Moreover, using a cell-based GAL4-NR LBD cotransfection assay, it was found that T0901317 at a dose of 2 μM was a potent in repressing both GAL4-RORα and GAL4-RORγ. Furthermore, T0901317 was demonstrated its selectivity that T0901317 inhibited the constitutive transactivation activity of both GAL4-RORα and GAL4-RORγ with little or no activity on GAL4-RORβ T0901317 demonstrated an excellent dose response, with an estimated IC50 values of 2.0 for RORα and 1.7 μM for RORγ, respectively. [1, 2, 3]

The role of T0901317 on ABCA1 expression in vivo was also studied. We treated 11-week-old APP23 mice orally by gastric gavage for 6 days with 50 mg/kg/day T0901317. The treatment of APP23 mice resulted in a substantial increase in the expression of ABCA1, however the expression of APP did not change. [4]
