BioAssay: AID 2455

Vitamin D Receptor Selectivity Assay for Inhibitors of the Interaction of Thyroid Hormone Receptor and Steroid Receptor Coregulator 2

Thyroid receptor (TR) regulates many homeostatic processes including basal metabolism, cardiovascular function, body weight, and lipid trafficking. TR modulators are potential therapeutics for obesity and hyperlipidemias but current thyroid analogs have undesirable side effects, particularly cardiac stimulation. This secondary assay characterized compounds identified in the qHTS for Inhibitors of more ..

NCGC Assay Overview:

Thyroid receptor (TR) regulates many homeostatic processes including basal metabolism, cardiovascular function, body weight, and lipid trafficking. TR modulators are potential therapeutics for obesity and hyperlipidemias but current thyroid analogs have undesirable side effects, particularly cardiac stimulation. This secondary assay characterized compounds identified in the qHTS for Inhibitors of the Interaction of Thyroid Hormone Receptor and Steroid Receptor Coregulator 2 (PubChem AID 1485) for selectivity against the vitamin D receptor (VDR). This assay detects interaction of the ligand-binding domain of human VDR with an Alexa Fluor 647 labeled SRC2-3 peptide, corresponding to a 20 amino acid region of the nuclear receptor interaction domain (Teichert et al., 2009). Small molecule inhibitors that block the interaction of VDR and SRC2-3 are detected by a decrease in fluorescence polarization.

Protocol
NCGC Assay Protocol Summary:

Twenty uL/well 1 uM VDR and 5 nM Alexa Fluor 647 SRC2-3 peptide in buffer (25 mM PIPES, pH 6.75, 50 mM NaCl, 0.01% NP-40, 6 uM LG190178, and 4% DMSO) was dispensed into black solid 384-well plates (Costar 3710) using a Biomek FX (Beckman Coulter) liquid handling system. Following transfer of 260 nL compound (ranging from 7 nM to 130 uM), the plates were incubated 3 hr at ambient temperature. The plates were read by an Envision (Perkin Elmer) to detect fluorescence polarization of Alexa Fluor 647 (620 nm excitation and 688 nm emission).
