Name: Summary of probe development efforts to identify novel modulators of the Retinoic acid receptor-related Orphan Receptors (ROR).

Description:

Nuclear receptors are a family of small molecule and hormone-regulated transcription factors that share conserved DNA-binding and ligand-binding domains. Small pharmacological compounds able to bind to the cleft of the ligand-binding domain could alter its conformation and subsequently modify transcription of target genes. Such ligand agonists and/or antagonists have already been successfully designed for 23 nuclear receptors among the 48 previously identified in the human genome (1-3). RORalpha (RORalpha; RORA; NR1F1) is one of three related orphan nuclear receptors, including RORbeta (RORbeta]; RORB; NR1F2) and RORgamma (RORgamma; RORC; NR1F3), known as "Retinoic Acid Receptor-related orphan receptors" (4).

RORA has unusual potential as a therapeutic target for the "metabolic syndrome" which results in pathologies such as insulin resistance, dyslipidemia, hypertension, and a pro-inflammatory state, that greatly elevates the risk of diabetes and atherosclerosis (5).The related RORC demonstrates significant expression in metabolic tissues such as liver, adipose, and skeletal muscle (6). These two receptors are implicated in several key aspects of this metabolic pathogenesis. For instance, the staggerer mouse, which carries a homozygous germline inactivation of RORA, shows low body weight, high food consumption (7-9), elevated angiogenesis in response to ischemia (10), susceptibility to atherosclerosis (9), and an abnormal serum lipid profile (11). RORG null mice exhibit normal plasma cholesterol levels, but when bred with the RORA staggerer mice, the resulting RORalpha/gamma knockout exhibits hypoglycemia not found in the single mutant animals. These studies reveal the functional redundancy of RORa and RORg in regulating blood glucose levels and highlight the need for RORalpha/gamma ligands that can bind to these receptors and modulate their transcriptional activity.

Summary of Probe Development Effort:

Following primary compound profiling of a cell-based GAL4-human nuclear receptor profiling assay, certain compounds were identified as possible candidates for probe development. Compounds derived from these initial candidates were purchased as powders or synthesized at the SRIMSC and were tested for their ability to inhibit RORa and RORg in luciferase-based reporter assays performed at a single concentration of 10 micromolar or in dose response assays starting at a nominal concentration of 20 micromolar. Compounds were subsequently counterscreened against the liver X receptor (LXR) and the farnesoid X receptor (FXR) to determine selectivity in singlicate and in dose response assays. Finally, compounds of interest were tested at a single concentration of 10 micromolar against VP16 to determine whether they were non-selective or cytotoxic. These late stage efforts have been described in AID 2117.

The above probe development efforts resulted in the identification of two probes. The benzenesulfonamide compound SID 85257301 previously identified as a selective agonist of LXR (12) was identified here as a novel RORa/g inverse agonist probe that decreases the transcriptional activity of both ROR receptors (IC50 values = 2.0 and 1.73 micromolar, respectively). The second probe, SID 85257298 synthesized at the SRIMSC, was found to decrease RORa transcriptional activity (IC50 value = 2.47 micromolar). SID 85257298 represents an improvement over the prior art due to its lack of activity for LXR. Probe compound SID 85257298 does not have activity against RORg (IC50 > 20 micromolar). These two probes are useful tools for examining ROR biology.

The results of our probe development efforts can be found at http://mlpcn.florida.scripps.edu/index.php/probes/probe-reports.html. A probe report for SIDs 85257301 and 85257298 can be found in the Molecular Libraries Bookshelf (PubMed Books) (http://www.ncbi.nlm.nih.gov/books) under ML125 and ML124, respectively. A paper has been published (13).
