In the present application, oxygen-containing substituents, for example alkoxy, alkenyloxy, alkynyloxy, carbonyl, etc., include their homologues containing sulfur, for example thioalkyl, alkylthioalkyl, thioalkenyl, alkenyl-thioalkyl, thioalkynyl, thiocarbonyl, sulfone, sulfoxide, etc. Halo or halogen represents chlorine, fluorine, bromine, or iodine. Aryl represents carbocyclic aryl, heterocyclic aryl, or biaryl. Carbocyclic aryl is an aromatic cyclic hydrocarbon containing from 6 to 18 ring atoms. It can be monocyclic, bicyclic, or tricyclic, for example naphthyl, phenyl, or phenyl mono-, di-, or tri-substituted by one, two, or three substituents. Heterocyclic aryl is a monocyclic or bicyclic aromatic hydrocarbon containing from 5 to 18 ring atoms, one or more of which are heteroatoms selected from O, N, or S. Preferably there are one or two heteroatoms. Heterocyclic aryl represents, for example: pyridyl, indolyl, quinoxalinyl, quinolinyl, isoquinolinyl, benzothienyl, benzofuranyl, benzopyranyl, benzothiopyranyl, furanyl, pyrrolyl, thiazolyl, oxazolyl, isoxazolyl, triazolyl, tetrazolyl, pyrazolyl, imidazolyl, thienyl, oxadiazolyl, benzimidazolyl.

Inositol Phosphate Formation Assay: In order to determine the antagonist activity in the human parathyroid calcium (PcaR) detection receptor, the compounds are tested in functional assays that measure the inhibition of calcium-induced inositol phosphate formation in CCL39 fibroblasts stably transfected with human PcaR. Cells are seeded in 24-well plates, and grown to confluence. The cultures are then labeled with [3 H] inositol (74 Mbq / milliliter) in a serum-free medium for 24 hours. After labeling, the cells are washed once with a modified Hepes regulated salt solution (mHBS: 130 mM NaCl, 5.4 mM KCl, 0.5 mM CaCl2, 0.9 mM MgSO4, 10 mM glucose, 20 mM HEPES, pH 7.4) , and incubated with mHBS at 37 ° C in the presence of LiCl, to block the activity of inositol monophosphatase. The test compounds are added 3 minutes before stimulating the PcaR with 5.5 mM calcium, and the incubations are continued for an additional 20 minutes. Subsequently, the cells are extracted with ice-cold 10 mM formic acid, and the inositol phosphates formed are determined using anion exchange chromatography and counting with liquid scintillation.
Assay for free intracellular calcium: An alternative method to determine antagonism in PcaR is to measure the inhibition of intracellular calcium transients stimulated by extracellular calcium.
CCL39 fibroblasts stably transfected with human PcaR are seeded at 40,000 cells / well in 96-well Viewplate plates and incubated for 24 hours. The medium is then removed and replaced with fresh medium containing Fluo-3 AM 2μM (Molecular Probes, Leiden, The Netherlands). In routine experiments, cells are incubated at 37 ° C with 5 percent C02 for 1 hour. Then, the plates are washed twice with mHBS, and the wells are refilled with 100 microliters of mHBS containing the test compounds. The incubation is continued at room temperature for 15 minutes. To record the changes of free intracellular calcium, the plates are transferred to a fluorescence imaging plate reader (Molecular Devices, Sunnyvale, CA, E.U.A.). A baseline is recorded consisting of 5 measurements of 0.4 seconds each (laser excitation at 488 nanometers). Then the cells are stimulated with calcium (2.5 mM final), and the fluorescence changes are recorded over a period of 3 minutes. When measured in the above assays, the Agents of the Invention typically have IC50s in the range of about 1,000 nM down to about 10 nM or less. It is now well established that the controlled treatment of patients with parathyroid hormone (PTH) and its analogues and fragments can have a pronounced anabolic effect on bone formation. Therefore, it can use compounds that promote the release of parathyroid hormone, such as the Agents of the Invention, to prevent or treat bone conditions that are associated with increased calcium depletion or excretion, or where stimulation of bone formation is desirable and the fixation of calcium in the bone.
