Description
Calcium-sensing receptor (CaSR) is a G protein-coupled receptor that is involved in calcium homeostasis. Activation of CaSR on parathyroid cells decreases the secretion of parathyroid hormone (PTH), which in turn reduces blood calcium concentration. NPS 2143 is a potent and selective antagonist of CaSR (IC50 = 43 nM) that stimulates PTH secretion from parathyroid cells in vitro (EC50 = 39 nM). It is effective in vivo, causing a sustained increase in plasma PTH in rats when given intravenously. Daily oral administration of NPS 2143 to osteopenic ovariectomized rats results in a dramatic increase in bone turnover, as well as increased circulating PTH levels.
Uses
NPS 2143 acts as a potent and selective antagonist for CaSR (Calcium-sensing receptor) which is involved in calcium blood concentration homeostasis.
Biochem/physiol Actions
NPS2143 is a phenylalkylamine calcilytic compound, and might be useful in treating autosomal dominant hypocalcemia. It serves as a blocking agent for hERG (human ether-a-go-go-related gene ) channel, CYP2D6 (cytochrome P450 2D6 ) and monoamine transporters.
in vivo
When infused intravenously in normal rats, NPS-2143 hydrochloride (SB-262470A hydrochloride) causes a rapid and large increase in plasma levels of PTH. Ca2+ receptor antagonists are termed calcilytics and NPS-2143 is the first substance (either atomic or molecular) shown to possess such activity[1].
When administered together with an antiresorptive agent (estradiol), NPS 2143 causes an increase in trabecular bone volume and bone mineral density in osteopenic rats[2].
