NPS 2143 hydrochloride
Selective Ca2+-sensing receptor antagonist. Blocks increases in cytoplasmic Ca2+ concentrations elicited by human Ca2+ receptors expressed in HEK293 cells (IC50 = 43 nM). Also stimulates parathyroid hormone secretion from bovine parathyroid cells (EC50 = 41 nM). Orally active calcilytic compound.
