生物活性 | NPS-2143 hydrochloride (SB-262470A hydrochloride), an orally active calcilytic agent, is a selective and potentcalcium ion-sensing receptor (CaSR)antagonist. NPS-2143 hydrochloride (SB-262470A hydrochloride) blocks increases in cytoplasmic Ca2+concentrations (IC50=43 nM) elicited by activating the Ca2+receptor in HEK 293 cells expressing the human Ca2+receptor[1][2]. | ||||||||||||||||
体外研究 (In Vitro) | NPS-2143 hydrochloride (SB-262470A hydrochloride) stimulates parathyroid hormone (PTH) secretion from bovine parathyroid cells with EC50of 41 nM. Moreover, NPS-2143 hydrochloride also blocks the inhibitory effects of calcimimetic NPS R-467 on PTH secretion from bovine parathyroid cells and the inhibitory effects of extracellular Ca2+ on isoproterenol-stimulated increases in cyclic AMP formation[1]. | ||||||||||||||||
体内研究 (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]. | ||||||||||||||||
