Calcium-Sensing Receptor

AMG-073 HCl (Cinacalcet HCl) represents a new class of compounds for the treatment of hyperparathyroidism known as calcimimetics, which reduce parathyroid hormone (PTH) synthesis and secretion by increasing the sensitivity of the parathyroid calcium-sensing receptor (CaR) to extracellular calcium.

NPS-2143 is a selective Ca2+-sensing receptor antagonist, shown to block increases in cytoplasmic Ca2+ concentrations elicited by human Ca2+ receptors expressed in HEK293 cells with an IC50 of 43 nM.

AMG-073 (Cinacalcet) represents a new class of compounds for the treatment of hyperparathyroidism.

NPS-2143 hydrochloride (SB-262470A hydrochloride), an orally active calcilytic agent, is a selective and potent calcium ion-sensing receptor (CaSR) antagonist.

Strontium ranelate is an antiosteoporotic agent which both increases bone formation and reduces bone resorption, resulting in a rebalance of bone turnover in favor of bone formation. This is similar to the effects of choline stabilized orthosilicic acid.

Evocalcet is a calcium-sensing receptor agonist. The calcium-sensing receptor (CaSR) is a Class C G-protein coupled receptor which senses extracellular levels of calcium ion.
